SUMMARY This summary highlights information contained elsewhere or incorporated by reference in this prospectus. Accordingly, it does not contain all of the information that may be important to you. You should read this entire prospectus carefully, including the information under "Risk Factors" and the consolidated financial statements and the notes thereto included elsewhere in this prospectus before making an investment decision. Unless the context otherwise requires, references to "we," "us" or "our" refer collectively to Gibraltar Steel Corporation and its subsidiaries. Unless otherwise stated, all information contained in this prospectus assumes no exercise of the over-allotment option granted to the underwriters. The Company We are a leading processor, manufacturer and provider of high value-added, high margin steel products and services. Since our initial public offering in 1993, we have continued to build upon our core competencies of processing and manufacturing by expanding into the metal processing, building and construction products and commercial heat-treating markets through strategic acquisitions and internal growth. We are now the second largest domestic commercial heat-treater and have become a major supplier of metal building and construction products. We have broadened our product lines and services, entered new geographic and end-user markets and expanded our customer base through the acquisition of 15 businesses for approximately $296 million and the investment of approximately $140 million in capital expenditures. As a result of this growth, we now have 54 facilities in 20 states and Mexico serving more than 10,000 customers in a variety of industries. Since our initial public offering, our operating approach and the successful execution of our growth strategy have enabled us to outperform most of our publicly traded competitors in the processor and service center industry with respect to net sales, EBITDA and net income growth. From 1993 through 2000, we achieved eight consecutive fiscal years of record net sales and EBITDA, and our net sales, EBITDA and net income increased at compound annual growth rates of 22.1%, 25.7% and 18.7%, respectively. In addition, our EBITDA margin expanded from 9.7% in 1993 to 12.0% in 2000. As a result of the general economic slowdown, net sales, EBITDA and net income for the first nine months of 2001 decreased by 9.8%, 24.1% and 47.9%, respectively, as compared to the results generated in the first nine months of 2000. We classify our operations into three segments--Processed Steel Products, Building Products and Heat Treating. Our operations utilize any one or a combination of more than 25 different processes to manufacture and deliver a variety of high-quality steel products and services. Our Processed Steel Products segment produces cold-rolled strip steel that is used in applications which demand more precise widths, improved surface conditions and tighter gauge tolerances than are supplied by primary producers of flat-rolled steel products, as well as heavy duty steel strapping that is used to close and reinforce packages such as cartons and crates. Our Building Products operations manufacture and distribute more than 5,000 building and construction products including steel lumber connectors, metal roofing and accessories, ventilation products and mailboxes. Our Heat Treating segment provides specialized heat-treating services which refine the metallurgical properties of customer-owned metal products for a variety of industries that require critical performance characteristics. We sell our products both domestically and internationally to manufacturers and distributors and, to a lesser extent, directly to end-users for a wide range of applications. Additionally, we sell our products to consumers through hardware and building products distributors and mass merchandisers. Our major commercial markets include the automotive, automotive supply, building and construction, steel, machinery and general manufacturing industries. 1

Our Opportunity The steel industry is comprised of primary steel producers, service centers, processors and end product manufacturers. Primary steel producers typically focus on the production and sale of standard size and tolerance steel to large volume purchasers, including steel processors. Service centers typically provide services such as storage and shipping, slitting and cutting to length. Steel processors, through the application of various higher value-added processes such as cold-rolling and specialized heat-treating methods, process steel of a precise grade, temper, tolerance and finish. End product manufacturers incorporate the processed steel into finished goods. We have developed a set of steel and metal processing core competencies as a processor operating between primary steel producers and end product manufacturers. Industry statistics indicate that although the number of service centers and processors has decreased from approximately 7,000 in 1980 to approximately 3,400 in 2000, annual sales by service centers and processors have increased from $30 billion in 1996 to $75 billion in 2000. Our industry has been impacted recently as manufacturers have increasingly outsourced non-core business functions and consolidated their suppliers to improve productivity and cost efficiency. We believe that manufacturer outsourcing and the consolidation of suppliers will continue to become more prevalent, resulting in increased demand for our products and services in the future. Our Competitive Strengths We have established a reputation as an industry leader in quality, service and innovation and have achieved a strong competitive position in our markets. We attribute this primarily to the following competitive strengths: . our ability to provide high value-added products and services; . our ability to identify and integrate acquisitions; . the diversification of our customers, products and services; . our commitment to quality; . the efficiency of our inventory purchasing and management; and . our experienced management team. Our Strategy Our strategic objective is to further enhance our position as a leading processor, manufacturer and provider of high value-added, high margin steel products and services. We plan to achieve this objective through the aggressive pursuit of our business strategy, which includes: . a focus on high value-added, high margin steel products and services; . a commitment to internal growth and continuous cost reduction; . a commitment to external growth through the acquisition of businesses which are immediately accretive to our earnings per share, have long-term growth potential and also complement, expand and enhance our products and services and broaden our markets and customer base; and . a dedication to quality, service and customer satisfaction. 2

Recent Developments On January 24, 2002, we issued a press release reporting our sales and earnings for the quarter and year ended December 31, 2001. We announced that sales in 2001 were $616 million, a decrease of 9.1% from sales of $678 million in 2000. In the fourth quarter of 2001, sales were $140 million, down 6.4% from $150 million in the fourth quarter of 2000. Net income in 2001 was $12.5 million, or $0.98 per diluted share, compared to $24.4 million, or $1.92 per diluted share, in 2000. Net income in the fourth quarter of 2001 was $1.5 million, or $0.12 per diluted share, compared to $3.2 million, or $0.26 per diluted share, in the fourth quarter of 2000.

RISK FACTORS You should carefully consider the following risks and uncertainties and all other information contained in this prospectus, or incorporated herein by reference, before you decide whether to purchase our common stock. Any of the following risks, should they materialize, could adversely affect our business, financial condition or operating results. As a result, the trading price of our common stock could decline and you could lose all or part of your investment. Our future operating results may be affected by fluctuations in steel prices. We may not be able to pass on increases in raw material costs to our customers. Our principal raw material is flat-rolled steel, which we purchase from multiple primary steel producers. The steel industry as a whole is very cyclical, and at times pricing can be volatile due to a number of factors beyond our control, including general economic conditions, labor costs, competition, import duties, tariffs and currency exchange rates. This volatility can significantly affect our raw material costs. We are required to maintain substantial inventories of steel to accommodate the short lead times and just-in-time delivery requirements of our customers. Accordingly, we purchase steel on a regular basis in an effort to maintain our inventory at levels that we believe are sufficient to satisfy the anticipated needs of our customers based upon historic buying practices and market conditions. In an environment of increasing raw material prices, competitive conditions will impact how much of the steel price increases we can pass on to our customers. To the extent we are unable to pass on future price increases in our raw materials to our customers, the profitability of our business could be adversely affected. The building and construction industry and the automotive industry account for a significant portion of our sales and reduced demand from these industries is likely to adversely affect our profitability. Sales of our products for use in the building and construction industry accounted for approximately 49%, 50%, 51% and 56% of our net sales in 1998, 1999, 2000 and for the first nine months of 2001, respectively. These sales were made primarily to retail home center chains and wholesale distributors. The building and construction industry is cyclical, with product demand based on numerous factors such as interest rates, general economic conditions, consumer confidence and other factors beyond our control. Sales of our products for use in the automotive industry accounted for approximately 30%, 32%, 30% and 26% of our net sales in 1998, 1999, 2000 and for the first nine months of 2001, respectively. Such sales include sales directly to auto manufacturers and to manufacturers of automotive components and parts. The automotive industry experiences significant fluctuations in demand based on numerous factors such as general economic conditions, consumer confidence and other factors beyond our control. We also sell our products to customers in other industries that experience cyclicality in demand for products, such as the steel and machinery and equipment industries. None of these industries individually represented more than 10% of our annual net sales in 2000. Downturns in demand from the building and construction industry, the automotive industry or any of the other industries we serve, or a decrease in the prices that we can realize from sales of our products to customers in any of these industries, could adversely affect our profitability. The success of our business is affected by general economic conditions and our business could be adversely impacted by an economic slowdown or recession. Periods of economic slowdown or recession in the United States or other countries, or the public perception that one may occur, could decrease the demand for our products, affect the availability and price of our products and adversely impact our business. In 2000, for example, we were somewhat impacted by the general slowing in the economy. That impact has continued, and in the first three quarters of 2001 we did not maintain the same 6

level of sales or profitability as in the first three quarters of 2000. Excluding the impact of any additional acquisitions that we may make during 2001, it may be difficult to achieve the same level of sales volume and net income in 2001 as we achieved last year. We may not be able to successfully identify, manage and integrate future acquisitions, and if we are unable to do so, we are unlikely to sustain our historical growth rates and our stock price may decline. Historically, we have grown through a combination of internal growth and external expansion through acquisitions and a joint venture. Although we intend to actively pursue our growth strategy in the future, we cannot provide any assurance that we will be able to identify appropriate acquisition candidates or, if we do, that we will be able to successfully negotiate the terms of an acquisition, finance the acquisition or integrate the acquired business effectively and profitably into our existing operations. Integration of an acquired business could disrupt our business by diverting management away from day-to-day operations. Further, failure to successfully integrate any acquisition may cause significant operating inefficiencies and could adversely affect our profitability and the price of our stock. Consummating an acquisition could require us to raise additional funds through additional equity or debt financing. Additional equity financing could depress the market price of our common stock. Additional debt financing could require us to accept covenants that limit our ability to pay dividends. Our business is highly competitive and increased competition could reduce our gross profit and net income. The principal markets that we serve are highly competitive. Competition is based primarily on the precision and range of achievable tolerances, quality, price, raw materials and inventory availability and the ability to meet delivery schedules dictated by customers. Our competition in the markets in which we participate comes from companies of various sizes, some of which have greater financial and other resources than we do and some of which have more established brand names in the markets we serve. Increased competition could force us to lower our prices or to offer additional services at a higher cost to us, which could reduce our gross profit and net income. Principal stockholders have the ability to exert significant control in matters requiring stockholder vote and could delay, deter or prevent a change in control of our company. Upon the consummation of this offering, approximately 38% (or approximately 37% if the underwriters' over-allotment option is exercised in full) of our outstanding common stock, including shares of common stock issuable under options granted which are exercisable within 60 days will be owned by Brian J. Lipke, Neil E. Lipke and Eric R. Lipke, each of whom is an executive officer of our company, Meredith A. Lipke, an employee of our company and Curtis W. Lipke, all of whom are siblings, Patricia K. Lipke, mother of the Lipke siblings, and certain trusts for the benefit of each of them. As a result, the Lipke family will continue to have significant influence over all actions requiring stockholder approval, including the election of our board of directors. Through their concentration of voting power, the Lipke family could delay, deter or prevent a change in control of our company or other business combinations that might otherwise be beneficial to our other stockholders. In deciding how to vote on such matters, the Lipke family may be influenced by interests that conflict with yours. Certain provisions of our charter documents and Delaware law could discourage potential acquisition proposals and could deter, delay or prevent a change in control of our company that our stockholders consider favorable and could depress the market value of our common stock. Certain provisions of our certificate of incorporation and by-laws, as well as provisions of the Delaware General Corporation Law, could have the effect of deterring takeovers or delaying or preventing changes in control or management of our company that our stockholders consider favorable and could depress the market value of our common stock. 7

Our certificate of incorporation provides that certain mergers, sales of assets, issuances of securities, liquidations or dissolutions, reclassifications or recapitalizations involving interested stockholders must be approved by holders of at least 80% of the outstanding voting stock, unless such transactions are approved by a majority of the disinterested directors or certain minimum price, form of consideration and procedural requirements are satisfied. An interested stockholder is defined as a holder of stock representing 20% or more of the shares of voting stock then outstanding. Our certificate of incorporation further provides that the affirmative vote of the holders of 80% of the total votes eligible to be cast in the election of directors is required to amend, alter, change or repeal such provisions. The requirement of such a super-majority vote could enable a minority of our stockholders to exercise veto powers over such amendments, alterations, changes or repeals. We are a Delaware corporation subject to the provisions of Section 203 of the Delaware General Corporation Law, an anti-takeover law. Generally, this statute prohibits a publicly-held Delaware corporation from engaging in a business combination with an interested stockholder for a period of three years after the date of the transaction in which such person became an interested stockholder, unless the business combination is approved in a prescribed manner. A business combination includes a merger, asset sale or other transaction resulting in a financial benefit to the stockholder. We anticipate that the provisions of Section 203 may encourage parties interested in acquiring us to negotiate in advance with our board of directors because the stockholder approval requirement would be avoided if a majority of the directors then in office approve either the business combination or the transaction that results in the stockholder becoming an interested stockholder. We depend on our senior management team and the loss of any member could adversely affect our operations. Our success is dependent on the management and leadership skills of our senior management team. The loss of any of these individuals or an inability to attract, retain and maintain additional personnel could prevent us from implementing our business strategy. We cannot assure you that we will be able to retain our existing senior management personnel or to attract additional qualified personnel when needed. We have not entered into employment agreements with any of our senior management personnel other than Brian J. Lipke, our Chairman of the Board and Chief Executive Officer. We are a holding company and rely on distributions from our subsidiaries to meet our financial obligations. We have no direct business operations other than our ownership of the capital stock of our subsidiaries. As a holding company, we are dependent on dividends or other intercompany transfers of funds from our subsidiaries to enable us to pay dividends and to meet our direct obligations. Future sales of our common stock could depress our market price and diminish the value of your investment. Future sales of shares of our common stock could adversely affect the prevailing market price of our common stock. If our existing stockholders sell a large number of shares, or if we issue a large number of shares, the market price of our common stock could significantly decline. Moreover, the perception in the public market that these stockholders might sell shares of common stock could depress the market for our common stock. Although, we, our directors, our executive officers and the selling stockholders have entered into lock-up agreements with Salomon Smith Barney, as representative of the underwriters, whereby we and they will not offer, sell, contract to sell, pledge, grant or otherwise dispose of, directly or indirectly, any shares of our common stock or securities convertible into or exchangeable or exercisable for shares of our common stock, except for the shares of common stock to be sold in this offering and certain other exceptions, for a period of 90 days from the date of this prospectus, without the prior written consent of Salomon Smith Barney, we and/or any of these persons may be released from this obligation, in whole or in part, by Salomon Smith Barney in its sole discretion at any time with or without notice. 8

We are subject to various environmental laws which may require us to incur substantial costs thereby reducing our profits. Our facilities are subject to many federal, state, local and foreign laws and regulations relating to the protection of the environment. Failure to comply with environmental laws, regulations and permits, or changes in such laws, including the imposition of more stringent standards for discharges into the environment, could result in substantial operating costs and capital expenditures in order to maintain compliance and could also include fines and civil or criminal sanctions, third party claims for property damage or personal injury, cleanup costs or temporary or permanent discontinuance of operations. Certain of our facilities have been in operation for many years and, over time, we and other predecessor operators of these facilities have generated, used, handled and disposed of hazardous and other regulated wastes. Environmental liabilities could exist, including cleanup obligations at these or at other locations where materials from our operations were disposed of, which could result in future expenditures that cannot be currently quantified and which could reduce our profits. A write-down of our goodwill may be required by recent accounting pronouncements which could materially impair our net worth. In July 2001, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 141 Business Combinations and Statement of Financial Accounting Standards No. 142 Goodwill and Other Intangible Assets. FAS 141 requires that all business combinations be accounted for under the purchase method only and that certain acquired intangible assets in a business combination be recognized as assets apart from goodwill. FAS 142 requires that ratable amortization of goodwill be replaced with periodic tests of the goodwill's impairment and that intangible assets other than goodwill should be amortized over their useful lives. As a result of our acquisition strategy, we have a material amount of goodwill recorded on our financial statements. If, as a result of the implementation of FAS 141 and/or FAS 142, we are required to write-down any of our goodwill, our net worth will be reduced. Since our credit agreement contains a covenant requiring us to maintain a minimum net worth, this reduction in net worth, if substantial, may result in an event of default under the credit agreement which would prevent us from borrowing additional funds and limit our ability to pay dividends. Our operations are subject to seasonal fluctuations which may impact our cash flow. Our revenues are generally lower in the first and fourth quarters primarily due to customer plant shutdowns in the automotive industry due to holidays and model changeovers, as well as reduced activity in the building and construction industry due to weather. In addition, quarterly results may be affected by the timing of large customer orders, by periods of high vacation concentration and by the timing and magnitude of acquisition costs. Therefore, our cash flow from operations may vary from quarter to quarter. If, as a result of any such fluctuation, our quarterly cash flow was significantly reduced, we may not be able to service the indebtedness under our credit agreement. A default in our credit agreement would prevent us from borrowing additional funds and limit our ability to pay dividends, and allow our lenders to enforce their liens against our personal property. FORWARD LOOKING STATEMENTS This prospectus and the documents incorporated by reference contain forward looking statements, including, without limitation, statements concerning conditions in the markets we serve and our business, financial condition and operating results and including, in particular, statements relating to our growth strategies. We use words like "believe," "expect," "anticipate," "intend," "future" and other similar expressions to identify forward looking statements. Purchasers of our common stock should not place undue reliance on these forward looking statements, which speak only as of their respective dates. These forward looking statements are based on our current expectations and are subject to a number of risks and uncertainties, including, without limitation, those identified under "Risk Factors" and elsewhere in this prospectus. Our actual operating results could differ materially from those predicted in these forward looking statements and any other events anticipated in the forward looking statements may not actually occur. 9

USE OF PROCEEDS We expect to receive net proceeds of approximately $36.5 million from this offering ($43.1 million if the underwriters exercise their over-allotment in full), after deducting underwriting discounts, commissions and our estimated offering expenses, based on an assumed offering price to the public of $15.60 per share (the last reported sale price on February 20, 2002). We will not receive any proceeds from the sale of the shares of common stock being sold by the selling stockholders. We intend to use the net proceeds from this offering to repay a portion of the borrowings outstanding under our existing credit facility, which expires in April 2003. In 2001, borrowings under our credit facility were used primarily to fund the acquisition of Pennsylvania Industrial Heat Treaters and capital expenditures. Our credit facility provides for a revolving credit line of up to $310 million. The amounts outstanding under our credit facility bear interest at various rates above the London InterBank Offered Rate (LIBOR) or at the agent bank's prime rate, as selected by us. We have entered into interest rate swap agreements which convert certain of our borrowings under the credit facility from variable interest indebtedness to fixed interest indebtedness. At September 30, 2001, amounts outstanding under our credit facility were approximately $221.7 million, bearing interest at a weighted average interest rate of 5.66%. See "Management's Discussion and Analysis of Financial Condition and Results of Operations--Liquidity and Capital Resources." Our credit facility is secured by substantially all of our accounts receivable, inventory, equipment and fixtures and other personal property, now owned or hereafter acquired. Our credit facility contains covenants restricting our ability to make capital expenditures, incur additional indebtedness, sell a substantial portion of our assets, merge or make acquisitions or investments in an amount in excess of $20 million, and obligates us to meet certain financial requirements. In addition, our credit facility contains certain restrictions on our ability to pay dividends. 10

DIVIDEND POLICY Since March 1999, we have declared quarterly cash dividends on our common stock as set forth in the table below. We may reconsider or revise this policy from time to time based upon conditions then existing, including, without limitation, our earnings, financial condition, capital requirements or other conditions our board of directors may deem relevant. In addition, our credit facility contains covenants that may restrict our ability to pay dividends. Such covenants include, among others, a requirement that we maintain a minimum net worth equal to $120 million plus 50% of our cumulative net income from June 30, 1997 ($163.7 million as of September 30, 2001) and comply with other financial ratios relating to our ability to pay our current obligations. Although we expect to continue to declare and pay cash dividends on our common stock in the future if earnings are available, we cannot assure you that either cash or stock dividends will be paid in the future on our common stock or that, if paid, the dividends will be in the same amount or at the same frequency as paid in the past.

EBITDA is commonly used as an analytical indicator and also serves as a measure of leverage capacity and debt servicing ability. EBITDA should not be considered as a measure of financial performance under accounting principles generally accepted in the United States. The items excluded from EBITDA are significant components in understanding and assessing financial performance. EBITDA should not be considered in isolation or as an alternative to net income, cash flows generated by operating, investing or financing activities or other financial statement data presented in our consolidated financial statements as an indicator of financial performance or liquidity. EBITDA as measured in this prospectus is not necessarily comparable with similarly titled measures for other companies. /(3)/See "Capitalization" for the unaudited pro forma balance sheet data assuming that consummation of this offering and application of the estimated proceeds therefrom to reduce indebtedness had occurred on September 30, 2001. 14

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Introduction Since our initial public offering in 1993, our operations have been characterized by the four key elements of our business strategy: a focus on high value-added, high margin steel products and services; a commitment to internal growth and continuous cost reduction; a commitment to external expansion through the acquisition of related businesses with long-term growth potential; and a dedication to quality, service and customer satisfaction. Because of changes in our activities from year to year, the results of operations for prior periods may not necessarily be comparable to, or indicative of, results of operations for current or future periods. Implementation of our business strategy has resulted in a compound annual growth rate for net sales of approximately 22.1% for the years 1993 through 2000, and a compound annual growth rate for income from operations of approximately 24.5% during the same period. Segments We are organized into three reportable segments on the basis of the production process, and products and services provided by each segment, identified as follows: (i) Processed Steel Products, which primarily includes the intermediate processing of wide, open tolerance flat-rolled sheet steel through the application of up to 12 different processes to produce high-quality, value-added coiled steel products to be further processed by customers. (ii) Building Products, which primarily includes the processing of sheet steel to produce a wide variety of building and construction products. (iii) Heat Treating, which includes a wide range of metallurgical heat treating processes in which customer-owned metal parts are exposed to precise temperatures, atmospheres and quenchants to improve their mechanical properties, durability and wear resistance. Results of Operations The following tables set forth for each of the periods presented certain income statement data in dollars and as a percentage of net sales. With respect to the interim periods presented, see the discussion of "Seasonality" below.

Net sales of $475.6 million for the nine months ended September 30, 2001, which included net sales of Milcor (acquired July 17, 2000) and Pennsylvania Industrial Heat Treaters (acquired February 13, 2001), decreased 9.8% from sales of $527.5 million for the nine months ended September 30, 2000. These decreases resulted primarily from changes in the general economy, particularly reduced production levels in the automotive industry. 16

Gross profit decreased to 18.8% of net sales for the third quarter ended September 30, 2001 from 20.1% for the prior year's third quarter. Gross profit decreased to 19.1% of net sales for the first nine months of 2001 from 20.3% for the nine months ended September 30, 2000. These decreases were due primarily to higher transportation, health insurance, utility, labor costs and fixed costs as a percentage of net sales due to lower sales volume in 2001 compared to the same periods for 2000, partially offset by lower raw material costs in 2001. Selling, general and administrative expenses increased to 12.7% and 12.5% of net sales for the third quarter and nine months ended September 30, 2001, in comparison to 10.4% and 11.0% of net sales for the same periods of 2000. These increases were primarily due to the non-cash charge of $1.0 million relating to the Company's E-Commerce investment and costs from the acquisitions of Milcor and Pennsylvania Industrial Heat Treaters, which have higher selling, general and administrative costs as a percentage of net sales than our existing operations, partially offset by decreases in incentive based compensation. As a result of the above, income from operations as a percentage of net sales for the third quarter ended September 30, 2001 decreased to 6.1% from 9.7% for the prior year's third quarter and to 6.7% for the nine months ended September 30, 2001 from 9.3% for the same period in the prior year. Interest expense decreased by approximately $1.3 million and $0.3 million for the third quarter and nine months ended September 30, 2001 over the prior year's comparable periods, primarily due to decreases in interest rates offset by interest costs related to higher average borrowings during 2001 to finance acquisitions and capital expenditures. As a result of the above, income before taxes decreased by $6.1 million and $17.0 million for the third quarter and nine months ended September 30, 2001 from the same periods in 2000. Income taxes for the third quarter and nine months ended September 30, 2001 approximated $2.4 million and $7.5 million and were based on a 40.5% effective tax rate in both periods. Segment Information Processed Steel Products. Net sales of $66.3 million for the third quarter ended September 30, 2001 decreased 16.9% from net sales of $79.8 million for the prior year's third quarter. Net sales of $192.7 million for the nine months ended September 30, 2001 decreased 23.9% from sales of $253.2 for the nine months ended September 30, 2000. These decreases were primarily due to changes in the general economy, particularly reduced production levels in the automotive industry. Income from operations decreased to 11.1% of net sales for the third quarter ended September 30, 2001 from 12.5% for the prior year's third quarter. Income from operations decreased to 11.5% of net sales for the nine months ended September 30, 2001 from 12.4% for the same period in 2000. These decreases were primarily due to higher health insurance and utility costs as a percentage of net sales, partially offset by lower raw material costs. Building Products. Net sales of $78.3 million for the third quarter ended September 30, 2001 decreased 2.0% from net sales of $79.8 million for the prior year's third quarter. Net sales of $228.3 million for the nine months ended September 30, 2001 increased 6.6% from sales of $214.2 million for the nine months ended September 30, 2000. The sales decrease in the third quarter of 2001 was primarily due to changes in the general economy. The sales increase for the nine months ended September 30, 2001 was primarily due to including the sales of Milcor (acquired July 17, 2000) partially offset by sales decreases at existing operations due to changes in the general economy. Income from operations decreased to 6.7% of net sales for the third quarter ended September 30, 2001 from 9.3% for the prior year's third quarter. Income from operations for the nine months ended September 30, 2001 decreased to 7.1% of net sales from 8.8% for the same period in 2000. These decreases were primarily due to 17

higher costs as a percentage of net sales from the Milcor acquisition, higher freight, transportation and utility costs at existing operations, and during the third quarter higher material costs. These cost increases were partially offset by decreases as a percentage of net sales in incentive based compensation and other employee costs at existing operations. Heat Treating. Net sales of $16.9 million for the third quarter ended September 30, 2001 decreased 9.8% from net sales of $18.7 million for the prior year's third quarter. Net sales of $54.6 million for the nine months ended September 30, 2001 decreased 9.1% from sales of $60.1 for the nine months ended September 30, 2000. These decreases were primarily due to changes in the general economy, particularly reduced production levels in the automotive industry, partially offset by including the net sales of Pennsylvania Industrial Heat Treaters (acquired February 13, 2001). Income from operations decreased to 9.7% of net sales for the third quarter ended September 30, 2001 from 13.0% for the prior year's third quarter. Income from operations decreased to 12.8% of net sales for the nine months ended September 30, 2001 from 17.2% for the same period in 2000. These decreases were primarily due to higher health insurance and utility costs as a percentage of net sales at existing operations, partially offset by decreases in incentive based compensation and by lower costs as a percentage of net sales resulting from the acquisition of Pennsylvania Industrial Heat Treaters. Year Ended December 31, 2000 Compared to Year Ended December 31, 1999 Consolidated Net sales increased $55.6 million, or 8.9%, to $677.5 million in 2000 from $621.9 million in 1999, despite the elimination of $19.4 million in sales from disposed of operations that were included in 1999 sales and a slowdown in the automotive and building and construction products markets in the fourth quarter of 2000. This increase primarily resulted from including the net sales of Milcor (acquired July 17, 2000) from its acquisition date, and a full year of net sales of Southeastern Heat Treating (acquired April 1, 1999), Weather Guard (acquired July 1, 1999), Hi-Temp (acquired August 1, 1999), Brazing Concepts (acquired November 1, 1999) and Hughes (acquired December 1, 1999), together with sales growth at existing operations. Cost of sales increased $47.8 million, or 9.7%, to $541.7 million in 2000 from $493.9 million in 1999. Cost of sales as a percentage of net sales increased to 80.0% in 2000 from 79.4% in 1999 primarily due to the impact of the slowdown in the automotive and construction products markets in the fourth quarter of 2000. Selling, general and administrative expenses increased $3.4 million, or 4.7%, to $75.9 million in 2000 from $72.5 million in 1999. Selling, general and administrative expenses as a percentage of net sales decreased to 11.2% in 2000 from 11.7% in 1999 primarily due to the elimination of expenses from disposed of operations and decreases in performance based compensation, partially offset by higher costs attributable to the 1999 and 2000 acquisitions. Interest expense increased $5.5 million from 1999 to 2000 due to higher borrowings as a result of the acquisitions and current year capital expenditures and due to a higher effective interest rate in 2000 than in 1999. As a result of the above, income before taxes decreased $1.1 million, or 2.6%, to $40.9 million in 2000 from $42.0 million in 1999. Income taxes approximated $16.6 million in 2000, resulting in a 40.5% effective tax rate. Segment Information Processed Steel Products. Net sales for 2000 remained at approximately the same level as the prior year at $321.3 million compared to $322.2 million in 1999. Sales growth from continuing operations offset approximately $19.4 million in sales from disposed of operations in 1999. Income from operations decreased 0.3% to $39.1 million in 2000 from $39.2 million in 1999. Operating margin for 2000 remained consistent with the prior year at 12.2%, primarily as a result of the favorable effect of the elimination of higher costs related to the disposed of operations offset by reduced higher margin sales due to 18

the slowdown in the automotive industry in the fourth quarter of 2000, higher raw material costs related to the automotive industry and an increase in performance-based compensation. Building Products. Sales increased $28.4 million, or 11.4%, to $277.7 million in 2000 from $249.3 million in 1999. This increase was primarily due to including the net sales of Milcor (acquired July 17, 2000), Weather Guard (acquired July 1, 1999) and Hughes (acquired December 1, 1999), partially offset by a decrease in net sales of existing operations due to changes in the general economy. Income from operations decreased by 11.8% to $22.5 million in 2000 from $25.5 million in 1999. Operating margin decreased to 8.1% in 2000 from 10.2% in 1999. This decrease was due to reduced sales volume from existing operations, increased transportation costs, fixed employee costs and higher direct labor costs related to the acquisition of Milcor, partially offset by a decrease in performance-based compensation. Heat Treating. Net sales increased $28.1 million, or 55.8%, to $78.5 million in 2000 from $50.4 million in 1999. This increase was primarily due to including the net sales of Southeastern Heat Treating (acquired April 1, 1999), Hi-Temp (acquired August 1, 1999) and Brazing Concepts (acquired November 1, 1999). Income from operations increased 55.3% to $13.1 million in 2000 from $8.4 million in 1999 primarily due to higher sales volumes from the acquisitions of Southeastern Heat Treating, Hi-Temp and Brazing Concepts. Operating margin for 2000 decreased slightly to 16.6% from 16.7% in 1999 due to increases in utility and direct labor costs offset by decreased costs related to performance-based compensation and higher margins resulting from the acquisitions of Southeastern Heat Treating, Hi-Temp and Brazing Concepts. Year Ended December 31, 1999 Compared to Year Ended December 31, 1998 Consolidated Net sales increased $64.0 million, or 11.5%, to $621.9 million in 1999 from $557.9 million in 1998. This increase primarily resulted from including the net sales of Southeastern Heat Treating (acquired April 1, 1999), Weather Guard (acquired July 1, 1999), Hi-Temp (acquired August 1, 1999), Brazing Concepts (acquired November 1, 1999) and Hughes (acquired December 1, 1999) from their respective acquisition dates, and a full year of net sales of Solar (acquired March 1, 1998), Appleton (acquired April 1, 1998), USP (acquired June 1, 1998) and Harbor (acquired October 1, 1998), together with sales growth at existing operations. Cost of sales increased $37.5 million, or 8.2%, to $493.9 million in 1999 from $456.4 million in 1998. Cost of sales as a percentage of net sales decreased to 79.4% in 1999 from 81.8% in 1998. This improvement was due to the 1999 and 1998 acquisitions, which have historically generated higher margins than our existing operations, and lower raw material costs at existing operations. Selling, general and administrative expenses increased $15.5 million, or 27.1%, to $72.5 million in 1999 from $57.0 million in 1998. Selling, general and administrative expenses as a percentage of net sales increased to 11.7% in 1999 from 10.2% in 1998. This increase was due to higher costs as a percentage of net sales attributable to the 1999 and 1998 acquisitions, and performance-based compensation linked to our sales and profitability. Interest expense increased by $2.0 million from 1998 to 1999 primarily due to higher borrowings in 1999 as a result of our current year acquisitions and capital expenditures and due to a higher effective interest rate in 1999 than in 1998. As a result of the above, income before taxes increased $9.0 million, or 27.1%, to $42.0 million in 1999 from $33.1 million in 1998. Income taxes approximated $17.0 million in 1999, resulting in a 40.5% effective tax rate compared with a 40.0% effective tax rate in 1998. 19

Segment Information Processed Steel Products. Net sales decreased $5.8 million, or 1.8%, to $322.2 million in 1999 from $328.0 million in 1998. This decrease primarily resulted from a $3.9 million reduction in sales from a division that was sold in 1999 and from a concentration of efforts to eliminate lower margin sales. Income from operations increased 9.9% to $39.2 million in 1999 from $35.7 million in 1998. Operating margin for 1999 increased to 12.2% from 10.9% in 1998. These improvements were primarily due to lower raw material costs partially offset by higher employee costs. Building Products. Net sales increased $47.5 million, or 23.5%, to $249.3 million in 1999 from $201.8 million in 1998. This increase primarily resulted from including the net sales of Weather Guard (acquired July 1, 1999) and Hughes (acquired December 1, 1999) and the net sales of Solar (acquired March 1, 1998), Appleton (acquired April 1, 1998) and USP (acquired October 1, 1998), together with sales growth at existing operations. Income from operations increased 37.2% to $25.5 million in 1999 from $18.6 million in 1998, primarily due to higher sales volumes from the acquisitions of Weather Guard, Hughes, Solar, Appleton and USP. Operating margin for 1999 increased to 10.2% from 9.2% in 1998, primarily due to the 1999 and 1998 acquisitions and lower raw material costs at existing operations. Heat Treating. Net sales increased $22.3 million, or 79.3%, to $50.4 million in 1999 from $28.1 million in 1998. This increase primarily resulted from including the net sales of Hi-Temp (acquired August 1, 1999) and Brazing Concepts (acquired November 1, 1999) and the net sales of Harbor (acquired October 1, 1998), together with sales growth at existing operations. Income from operations increased 75.6% to $8.4 million in 1999 from $4.8 million in 1998 primarily due to higher sales volumes from the acquisitions of Hi-Temp, Brazing Concepts and Harbor. The operating margin of 16.7% in 1999 decreased only slightly from 17.0% in 1998 since the Brazing Concepts and Harbor acquisitions generated margins similar to those of existing operations. Liquidity and Capital Resources Our principal capital requirements are to fund our operations, including working capital requirements, the purchase and funding of improvements to our property and equipment and to fund acquisitions. Our working capital increased approximately 17.3% to $132.4 million at December 31, 2000 from $112.9 million at December 31, 1999. This increase resulted primarily from the inclusion of inventories from the Milcor acquisition in July 2000 and a decrease in accounts payable and accrued expenses resulting from decreased purchases during the fourth quarter of 2000 in response to the slowdown in the automotive and construction products markets. Working capital decreased $18.8 million to $113.6 million at September 30, 2001 from December 31, 2000, primarily due to the use of working capital to pay down long-term debt related to our revolving credit facility. Long-term debt decreased to 55.1% of total capitalization at December 31, 2000, despite increasing by $20.2 million to $255.5 million. Long-term debt decreased $29.0 million to $226.5 million, or 51.1% of total capitalization, at September 30, 2001. Additionally, shareholders' equity increased 12.3% to $208.3 million at December 31, 2000 and increased 4.0% to $216.7 million at September 30, 2001. Our primary sources of liquidity are cash provided by operating activities and our revolving credit facility. Net cash provided by operating activities primarily represents net income plus non-cash charges for depreciation and amortization and changes in working capital positions. Net cash provided by operating activities for 1998, 1999, 2000 and the nine months ended September 30, 2001 was $13.3 million, $60.7 million, $34.1 million and $55.7 million, respectively. 20

Net cash used for investing activities for 1998, 1999, 2000 and the nine months ended September 30, 2001 was $121.3 million, $84.5 million, $54.7 million and $22.3 million, respectively. A significant portion of the net cash used for investment activities represents capital expenditures and our acquisitions of Solar, USP, Appleton and Harbor Metal in 1998; Southeastern Heat Treating, Weather Guard, Hi-Temp, Brazing Concepts and Hughes in 1999; Milcor in 2000 and Pennsylvania Industrial Heat Treaters in February 2001. Our credit facility, which expires in April 2003, was amended in 2000 to increase the capacity of our revolving credit line to $310 million. Borrowings thereunder are secured with our accounts receivable, inventories and personal property and equipment. At September 30, 2001, $221.7 million was outstanding under our credit facility. At September 30, 2001, we had interest rate swap agreements outstanding which effectively converted $50 million of borrowings under our revolving credit agreement to fixed rates ranging from 7.47% to 8.18%. We account for interest rate swap agreements on an accrual basis. Additional borrowings under the revolving credit facility carry interest at LIBOR plus a fixed rate. The weighted average interest rate of these borrowings was 5.66% at September 30, 2001. We intend to use the net proceeds of this offering to repay a portion of outstanding borrowings under our credit facility. See "Use of Proceeds." Upon consummation of this offering and application of the net proceeds therefrom, aggregate borrowings outstanding under the credit facility will be approximately $177.7 million. We anticipate that we will be able to satisfy such obligations out of funds generated from operations. The availability under our credit facility after application of the net proceeds of this offering will be approximately $132.3 million. We believe that this availability, together with funds generated from operations, will be sufficient to provide us with the liquidity and capital resources necessary to fund our anticipated working capital requirements for at least the next twelve months. In addition, we believe that we will have the financial capability to incur additional long-term indebtedness if that becomes appropriate in connection with our internal and external expansion strategies. Effects of Inflation We do not believe that inflation has had a material effect on our results of operations over the periods presented. Seasonality Our revenues are generally lower in the first and fourth quarters primarily due to customer plant shutdowns in the automotive industry due to holidays, as well as model changeovers and reduced activity in the building and construction industry due to weather. In addition, quarterly results may be affected by the timing of large customer orders, by periods of high vacation concentration and by the timing and magnitude of acquisition costs. Therefore, our operating results for any particular quarter are not necessarily indicative of results for any subsequent quarter or for the full year. Quantitative and Qualitative Disclosures about Market Risk In the ordinary course of business, we are exposed to various market risk factors, including changes in general economic conditions, competition and raw materials pricing and availability. In addition, we are exposed to market risk, primarily related to our long-term debt. To manage interest rate risk, we use fixed and variable rate debt. We also enter into interest rate swap agreements that convert our variable rate debt to fixed rate debt. At September 30, 2001, we had $50 million of revolving credit borrowings that was fixed rate debt pursuant to these agreements. The following table summarizes the principal cash flows and related interest rates of our long-term debt at December 31, 2000 by expected maturity dates. The weighted average interest rates are based on the actual rates 21

that existed at December 31, 2000. The variable rate debt consists primarily of the credit facility, of which $250,251,000 is outstanding at December 31, 2000. The credit facility matures during 2003 and we anticipate extending this facility. A 1% increase or decrease in interest rates would change the 2001 interest expense by approximately $2.0 million. 2006 and 2001 2002 2003 2004 2005 After Total ------- ------- -------- ------- ------- -------- -------- (dollar amounts in thousands) Long-term debt (fixed) $ 127 $ 413 $ 124 $ 129 $ 80 $1,229 $ 2,102 Weighted average interest rate 6.95% 6.99% 6.86% 6.93% 7.00% 7.00% Long-term debt (variable) $ 200 $ 400 $250,751 $ 500 $ 400 $1,500 $253,751 Weighted average interest rate 8.66% 8.66% 8.66% 5.58% 5.58% 5.58% Interest rate swaps (notional amount) $50,000 $50,000 $ 50,000 $50,000 $10,000 -- Interest pay rate 7.99% 7.99% 7.99% 7.99% 7.47% -- Interest receive rate 8.70% 8.70% 8.70% 8.70% 8.70% -- The fair value of the long-term debt is $253,751,000 at December 31, 2000. Recent Accounting Pronouncements In June 1998, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 133 Accounting for Derivative Instruments and Hedging Activities. FAS No. 133 requires recognition of the fair value of derivatives in the statement of financial position, with changes in the fair value recognized either in earnings or as a component of other comprehensive income dependent upon the hedging nature of the derivative. This Statement was implemented in 2001 and did not have a material impact on our earnings. In July 2001, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 141 Business Combinations and Statement of Financial Accounting Standards No. 142 Goodwill and Other Intangible Assets. FAS No. 141 requires that all business combinations be accounted for under the purchase method only and that certain acquired intangible assets in a business combination be recognized as assets apart from goodwill. FAS No. 142 requires that ratable amortization of goodwill be replaced with periodic tests of the goodwill's impairment and that intangible assets other than goodwill should be amortized over their useful lives. Implementation of FAS No. 141 and FAS No. 142 is required for fiscal 2002. The Financial Accounting Standards Board published FAS No. 141 and FAS No. 142 in late July 2001. Management is currently assessing the impact FAS No. 141 and FAS No. 142 will have on our results of operations. 22

BUSINESS General We are a leading processor, manufacturer and provider of high value-added, high margin steel products and services. We utilize any one or a combination of several different processes at each of our operating facilities to add substantial value to raw materials acquired from primary steel and other metal producers. Underlying each of these processes and services is a common set of core competencies in steel and metal processing. These core competencies are the foundation upon which all of our operations and products and services are based. We classify our operations into three segments--Processed Steel Products, Building Products and Heat Treating. Our Processed Steel Products segment produces a wide variety of cold-rolled strip steel products, coated sheet steel products and strapping products in 15 facilities in 6 states and Mexico. Our processed cold-rolled strip steel products comprise a part of the cold-rolled sheet steel market that is defined by more precise widths, improved surface conditions, more diverse chemistry and tighter gauge tolerances than are supplied by primary manufacturers of flat-rolled steel products. Our cold-rolled strip steel products are sold to manufacturers in the automotive, automotive supply, power and hand tool and hardware industries, as well as to other customers who demand critical specifications in their raw material needs. Our coated sheet steel products, which include galvanized, galvalume and pre-painted sheet products, are sold primarily to the commercial and residential metal building industry for roofing and siding applications. Our heavy duty steel strapping products are used to close and reinforce packages such as cartons and crates for shipping. Our Building Products segment primarily includes the processing of sheet steel to produce a wide variety of building and construction products. Many of our building and construction products meet and exceed increasingly stringent building codes and insurance company requirements governing both residential and commercial construction. This segment's products are sold to major home center stores, lumber and building material wholesalers, buying groups, discount stores, distributors and general contractors engaged in residential, industrial and commercial construction. Our Heat Treating segment operates 14 facilities in nine states. They provide a wide array of processes which refine the metallurgical properties of customer-owned metal products for a variety of consumer and industrial applications where critical performance characteristics are required. Note 16 to our consolidated financial statements included elsewhere in this prospectus provides information related to our business segments in accordance with generally accepted accounting principles. Summary information concerning our business segments for 1998, 1999 and 2000 is set forth below. 1998 1999 2000 -------- -------- -------- (in thousands) NET SALES Processed Steel Products. $328,022 $322,216 $321,361 Building Products........ 201,821 249,320 277,706 Heat Treating............ 28,101 50,382 78,473 -------- -------- -------- Total............... $557,944 $621,918 $677,540 ======== ======== ======== OPERATING INCOME Processed Steel Products. $ 35,673 $ 39,216 $ 39,111 Building Products........ 18,587 25,507 22,491 Heat Treating............ 4,787 8,408 13,059 Corporate................

Our Position in the Industry The steel industry consists of primary steel producers, service centers, processors and end product manufacturers. Primary steel producers typically focus on the production and sale of standard size and tolerance steel to large volume purchasers, including steel processors. Service centers typically provide services such as storage and shipping, slitting and cutting to length. Steel processors, through the application of various higher value-added processes such as cold-rolling and specialized heat-treating methods, process steel of a precise grade, temper, tolerance and finish. End product manufacturers incorporate the processed steel into finished goods. 24

We have developed a set of steel and metal processing core competencies operating as a processor between primary steel producers and end product manufacturers. Industry statistics indicate that although the number of service centers and processors has decreased from approximately 7,000 in 1980 to approximately 3,400 in 2000, annual sales by service centers and processors have increased from $30 billion in 1996 to $75 billion in 2000. Over the past five years, we have built upon our core competencies to increase our production of end products and have become the second largest domestic commercial heat-treater and a major supplier of metal building and construction products. Our successful expansion into end product manufacturing has given us access to new, attractive markets, including the home improvement industry with its $200 billion in annual sales, the metal roofing market with its $500 million in annual sales and the commercial heat-treating market with its $2 billion in annual sales. We are also the largest domestic manufacturer of mailboxes and the second largest domestic manufacturer of steel lumber connectors. Our industry has been impacted recently as manufacturers have increasingly outsourced non-core business functions and consolidated their suppliers to improve productivity and cost efficiency. These trends have created opportunities for our company to provide additional products and services to new customers and markets. We have been able to capitalize on these trends because of: . the breadth of our products and services; . our reputation for quality and customer service; and . our ability to meet our customers' requirements for critical specifications and demanding tolerances. As a result, the demand for our products and services has grown in recent years. We believe that manufacturer outsourcing and the consolidation of suppliers will continue to become more prevalent, resulting in increased demand for our products and services in the future. Our Competitive Strengths We have established a reputation as an industry leader in quality, service and innovation and have achieved a strong competitive position in our markets. We attribute this primarily to the following competitive strengths: Ability to Provide High Value-Added Products and Services. Our sophisticated technology, state-of-the-art equipment and exacting quality control measures have allowed us to provide high value-added products and services utilizing the most complex and demanding processes in our industry. These capabilities have enabled us to focus on the manufacture of end products and to realize higher margins than many of our competitors who provide less complex processes and services. Identification and Integration of Accretive Acquisitions. Our growth has been driven largely by our ability to identify and integrate strategic acquisitions that are immediately accretive to our earnings per share, expand our customer base, provide access to new markets, product lines and services and promote long-term growth. As an active acquiror, we are continually presented with acquisition opportunities and are frequently considered the acquiror of choice. Our experience has enabled us to identify those acquisitions that provide us with the greatest likelihood of immediate profitability and growth potential. Generally, we retain the existing management and corporate identity of our acquired companies and preserve their customer and supplier relationships, facilitating a seamless transition. We provide our acquired businesses with access to our management, operating expertise, capital, infrastructure and other resources. Diversified Customers, Products and Services. As a result of our growth, we have diversified our customers, products and services. Currently we have more than 10,000 active customers across all 50 states, Canada and Mexico. No single customer accounted for more than 7% of our net sales in 2000. We offer a wide variety of processing, including heat-treating, to customers in the automotive, steel, machinery, power and hand tool, furniture and general manufacturing industries. We derive a greater percentage of our sales from high 25

margin, end-user products than many publicly traded steel processors. In fiscal 2000, approximately one-half of our revenue came from the sale of our more than 5,000 manufactured end products to home centers, building material wholesalers, buying groups, discount stores, HVAC distributors and residential, industrial and commercial contractors. Our diversification reduces our dependence on any particular customer, product or service. Commitment to Quality. We place great importance on providing our customers with high-quality products for critical use applications. By carefully selecting our raw material vendors, primarily flat-rolled steel producers, and using computerized inspection and analysis, we ensure that the steel entering our production processes will meet the most critical specifications of our customers. To ensure that such specifications are met, we follow carefully documented procedures utilizing statistical process control systems linked directly to processing equipment in order to monitor all stages of production. Physical, chemical and metallurgical analyses are performed throughout the production process to verify that mechanical and dimensional properties, cleanliness, surface characteristics and chemical content are within specification. In addition, all of our facilities that provide services or products to the automotive industry, including 13 of our heat-treating facilities, are QS 9000 certified. QS 9000 is the quality designation that the automotive industry requires of its suppliers. Efficient Inventory Purchasing and Management. Our inventory consists primarily of flat-rolled steel. We purchase our inventory from numerous suppliers under short-term contracts of one year or less and, to a lesser extent, on the spot market on an as-needed basis. In 2000, we purchased $1 million or more of steel and other metals from 39 different suppliers. Through careful purchasing and close monitoring, our inventory turned an average of 5.3 times per year over our last five fiscal years, compared to an industry average for steel processors and service centers of approximately 4.5 times per year over the same period. Our inventory purchasing and management strategy allows us to react quickly to pricing and demand fluctuations in the metals markets, enabling us to manage our working capital more efficiently. Experienced Management Team. We have established and continue to maintain a strong management team. The seven most senior members of our management team have more than 200 years of combined service with our company. The management team has successfully guided us through various economic cycles and business environments and continues to provide us with a depth and continuity of experience. Under their leadership, we have been profitable every year since 1976. Business Strategy Our strategic objective is to further enhance our position as a leading processor, manufacturer and provider of high value-added, high margin steel products and services. We plan to achieve this objective through the aggressive pursuit of our business strategy, which includes: Focus on High Value-Added, High Margin Products and Services. We concentrate on processing, manufacturing and providing high value-added steel products and services that typically generate high margins. This focus, together with our ability to deliver consistently reliable products and services, has significantly contributed to profitability. Unlike many of our competitors, approximately half of our revenue is derived from manufactured end products. Since our initial public offering, we have entered the high margin building and construction products and commercial heat-treating markets. Commitment to Internal Growth and Continuous Cost Reduction. We have an ongoing commitment to grow and improve the profitability of our existing operations. To achieve this goal, we seek to expand our existing product lines into new markets and related products and focus on rigorous cost containment. We have made ongoing investments in new and existing production equipment to improve yield, lower overall manufacturing costs and expand capacity. Since 1993, we have invested approximately $140 million in capital expenditures to improve our existing businesses. Additionally, we seek to reduce costs in the area of inventory management by using a proprietary inventory control system to purchase, monitor and allocate inventory throughout the entire production process. 26

Commitment to External Expansion. We remain committed to expansion through the acquisition of businesses immediately accretive to our earnings per share with long-term growth potential that also complement our existing businesses, expand and enhance our products and services, broaden our markets and increase our customer base. Implementing our strategy of acquiring companies to increase our business, customer and geographic diversification, since our initial public offering we have made the following 15 acquisitions for an aggregate cash purchase price of approximately $296 million: Date Acquired Company Business Description - ------------- ------- -------------------- February 2001 Pennsylvania Industrial Provider of heat-treating to parts that have been Heat Treaters manufactured using powdered metallurgy July 2000 Milcor Manufacturer of metal building products, including registers, vents, bath cabinets, access doors, roof hatches and telescoping doors December 1999 Hughes Manufacturing Provider of steel lumber connectors and other building products November 1999 Brazing Concepts Provider of heat-treating processes August 1999 Hi-Temp Provider of heat-treating processes July 1999 Weather Guard Manufacturer and distributor of metal building products, including rain-carrying systems (gutters and gutter accessories), metal roofing and roofing accessories and assorted other products such as soffit and fascia April 1999 Southeastern Heat Treating Provider of heat-treating processes October 1998 Harbor Metal Treating Provider of heat-treating processes June 1998 United Steel Products Manufacturer of steel lumber connectors and other building products April 1998 Appleton Supply Manufacturer of metal building products, including roof edging and flashing March 1998 The Solar Group Manufacturer of metal building products, including ventilation products and accessories and a complete line of mailboxes May 1997 Specialty Heat Treating Provider of heat-treating processes January 1997 Southeastern Metals Manufacturer of galvanized steel, aluminum and Manufacturing copper products, including metal roofing and storm panel systems February 1996 Carolina Commercial Provider of heat-treating processes Heat Treating April 1995 Hubbell Steel Processor and supplier of galvanized, galvalume and pre-painted steel products 27

Dedication to Quality, Service and Customer Satisfaction. We are dedicated to providing our customers with high-quality products for just-in-time delivery, enabling us to establish strong relationships with existing customers as well as attract new customers. Accordingly, we have made significant investments in state-of-the-art equipment, technology and facilities. In addition, our experienced team of skilled computer technicians and managers provide solutions to our customers' inventory control problems. We have an inventory control system that allows customers to directly enter orders, monitor work in progress and receive invoices electronically. All of our facilities that provide services or products to the automotive industry, including 13 of our heat-treating facilities, are QS 9000 certified. As a result of our dedication to quality, service and customer satisfaction, we have received preferred supplier awards from many of our customers, including each of the major domestic automobile manufacturers. Products and Services Processed Steel Products Segment Cold-rolled Strip Steel. Our cold-rolled strip steel is used in applications which demand more precise widths, improved surface conditions and tighter gauge tolerances than are supplied by primary producers of flat-rolled steel products. Consistent with our strategy of focusing on high value-added products and services, we produce a broad range of fully processed cold-rolled strip steel products. We buy wide, open tolerance sheet steel in coils from primary steel producers and process it to specific customer orders by performing such computer-aided processes as cold reduction, annealing, edge rolling, slitting and cutting to length. Cold reduction is the rolling of steel to a specified thickness, temper and finish. Annealing is a thermal process which changes hardness and certain metallurgical characteristics of steel. Edge rolling involves conditioning edges of processed steel into square, full round or partially round shapes. Slitting is the cutting of steel to specified widths. Depending on customer specifications, one or more of these processes are utilized to produce strip steel of a precise grade, temper, tolerance and finish. Customers for our strip steel products include manufacturers in the automotive, automotive supply, power and hand tool, hardware and other industries. We operate nine rolling mills at our facilities in Cleveland, Ohio and Buffalo, New York, all of which are QS 9000 certified. Equipment at these facilities includes a computerized, three-stand, four-high tandem mill and eight single-stand, two- and four-high mills. We have the capability to process coils up to a maximum of 72 inch outside diameter and roll widths of up to 50 inches. Our rolling mills include automatic gauge control systems with hydraulic screwdowns allowing for microsecond adjustments during processing. Our computerized mills enable us to satisfy industry demand for a wide range of steel from heavier gauge and special alloy steels to low carbon and light gauge steels, in each case having a high-quality finish and precision gauge tolerance. This equipment can process flat-rolled steel to specific customer requirements for thickness tolerances as close as .00025 inches. We also operate a 56-inch reversing mill which we believe is one of the widest of its type in the specialty strip steel industry. Our rolling facilities are further complemented by 15 high convection annealing furnaces, which allow for shorter annealing times than conventional annealers. Three of our furnaces and bases employ state-of-the-art technology, incorporating the use of a hydrogen atmosphere for the production of cleaner and more uniform steel. As a result of our annealing capabilities, we are able to produce cold-rolled strip with improved consistency in terms of thickness, hardness, molecular grain structure and surface. We can produce certain strip steel products on oscillated coils, which wind strip steel similar to the way fishing line is wound on a reel. Oscillating the steel strips enables us to put at least six times greater volume of finished product on a coil than standard ribbon winding, allowing customers to achieve longer production runs by reducing the number of equipment shut-downs to change coils. Customers are thus able to increase productivity, reduce downtime, improve yield and lengthen die life. These benefits to customers allow us to achieve higher margins on oscillated products. To our knowledge, only a few other steel processors are able to produce oscillated coils, and we are not aware of any competitor that can produce 12,000 pound oscillated coils, the maximum size we produce. 28

Steel Strapping Products. Steel strapping is a banding and packaging material used to close and reinforce shipping units such as bales, boxes, cartons, coils, crates and skids. We are one of only four domestic manufacturers of high-tensile steel strapping, which is subject to strength requirements imposed by the American Society for Testing and Materials for packaging of different products for common carrier transport. This high tensile steel strapping is essential to producers of large, heavy products such as steel, paper and lumber where reliability of the packaging material is critical to the safe transport of the product. Our steel strapping facility is located in Buffalo, New York. Our QS 9000 certified strapping facility manufactures high tensile steel strapping by slitting, oscillating, heat-treating, painting and packaging cold-rolled coils. Steel strapping is cold-rolled to precise gauge on one of our rolling mills, which incorporates hydraulic screwdowns and automatic gauge controls with statistical charting. This process ensures strapping product of the most uniform gauge available and produces the maximum amount of strapping per pound of steel. All products are tested by on-site laboratory personnel for width, thickness and other physical and metallurgical properties. To meet the differing needs of our customers, we offer our strapping products in various thicknesses, widths and coil sizes. We also manufacture custom color and printed strapping. In addition, we offer related strapping products, such as seals and tools, and are able to manufacture tensional strapping for lighter duty applications. Coated Steel Products. Our coated steel products include pre-painted single bill packages, PVC spiral pre-painted product, purlin stock and liner panel stock, and galvanized, galvalume and pre-painted sheet product. We are capable of providing steel in more than 500 colors and in a variety of coatings, including galvanized and galvalume. Materials Management. We operate two state-of-the-art materials management facilities in New York and Michigan that link primary steel producers and end-user manufacturers by integrating the inventory purchasing, receiving, inspection, billing, storage and shipping functions and producing true just-in-time delivery of materials. Our facilities receive shipments of steel by rail and truck from primary steel producers, which retain ownership of the steel until it is delivered to the end-user manufacturer. We inspect the steel and store it in a climate-controlled environment on a specialized stacker crane and rack system. When an order is placed, we can deliver the steel to the end-user manufacturer within one hour using trucks that have been custom designed for facilitating the loading and unloading process. These facilities have proprietary and commercially available data processing systems that link the primary steel producer with the end-user manufacturer and also link both parties to the facilities. This gives them direct computer access to inventory on hand, in transit and on order, and enables such manufacturers to transmit their required release schedule through the computer. The shipping personnel are then notified via computer of customer orders that have been released and materials are promptly retrieved and shipped. We believe our materials management facilities provide benefits to primary steel producers and end-user manufacturers. The primary steel producers can ship materials to the facilities by rail rather than by truck, thereby enabling them to ship products more efficiently. In addition, utilizing the specialized facilities allows primary steel producers to deliver shipments just-in-time and with minimal transportation damage. The end-user manufacturers are able to utilize space previously used for raw material storage to more productive uses. The end-user manufacturers also reduce their inventory carrying costs since possession of inventory is not taken until it is shipped from the facilities. This enables end-user manufacturers to reduce their raw material inventory from several days or weeks to hours. Steel Pickling Joint Venture. We have a 31% interest in a joint venture that has two steel pickling operations in Ohio. After the hot-rolling process, the surface of sheet steel is left with a residue known as scale, which must be removed prior to further processing by a cleaning process known as pickling. This joint venture pickles steel on a toll basis, receiving fees for pickling services without acquiring ownership of the steel. 29

Building Products Segment We manufacture over 5,000 building and construction products for sale throughout the United States to home centers, building material wholesalers, buying groups, discount stores, HVAC distributors and residential, industrial and commercial contractors. Our building and construction products are manufactured primarily from galvanized and painted steel, as well as from aluminum and copper. Many of our wide array of building and construction products are designed to meet and exceed increasingly stringent building codes and insurance company requirements governing both residential and commercial construction. One such product is steel lumber connectors, of which we are the second largest manufacturer in the United States. Our other products include ventilation products and accessories; mailboxes; roof edging and flashing; aluminum soffit; drywall corner bead, wind brace and starter strip; painted coil stock; metal roofing and accessories; steel framing; rain-carrying systems, including gutters and accessories; bath cabinets; access doors; roof hatches and smoke vents; builders' hardware, such as door knockers, door stops, shelving and closet rods; and grilles, registers and defusers. Our 24 building and construction product facilities are located in Ohio, Michigan, Florida, Tennessee, Texas, Mississippi, Wisconsin, Missouri, Minnesota, California, North Carolina, New Jersey, Colorado and Georgia Heat Treating Segment As the second largest commercial heat treater in the United States, we provide a wide range of metallurgical heat-treating processes in which customer-owned metal parts are exposed to precise temperatures, atmospheres and quenchants and other conditions to improve their mechanical properties, durability and wear resistance. These processes include case-hardening, neutral-hardening and through-hardening, annealing, normalizing, vacuum hardening, carburizing, nitriding and brazing, as well as a host of other processes. These heat-treating processes can harden, soften or otherwise impart desired properties to parts made of steel, aluminum, copper, powdered metals and various alloys and other metals. We operate 14 heat-treating facilities in Pennsylvania, North Carolina, South Carolina, Tennessee, Georgia, Alabama, Michigan, Indiana and Illinois. We maintain a metallurgical laboratory at each facility with trained metallurgists providing a range of testing capabilities to add value to treated parts and enhance quality control. Consistent quality control is maintained by application of a statistical process control system and QS 9000 registration. Additionally, we maintain a fleet of trucks and trailers to provide rapid turnaround time for our customers. Due to time and costs associated with transporting materials and customers' need for just-in-time delivery of heat-treated products, the commercial heat-treating industry has developed as a regional industry concentrated in major industrial areas of the country. In addition, the commercial heat-treating industry has realized significant growth in recent years as many companies involved in the manufacture of metal components outsource their heat-treating requirements. We believe that our heat-treating facilities are strategically located to meet the needs of customers from a geographically diverse base of operations and to capitalize on the growing trend in outsourcing of heat-treating operations. Quality Control We place great importance on providing our customers with high-quality products for critical use applications. By carefully selecting our raw material vendors, primarily flat-rolled steel producers, and using computerized inspection and analysis, we ensure that the steel entering our production processes will meet the most critical specifications of our customers. To ensure that such specifications are met, we follow carefully documented procedures utilizing statistical process control systems linked directly to processing equipment in order to monitor all stages of production. Physical, chemical and metallurgical analyses are performed throughout the production process to verify that mechanical and dimensional properties, cleanliness, surface characteristics and chemical content are within specification. In addition, all of our facilities that provide services or products to the automotive industry, including 13 of our heat-treating facilities, are QS 9000 certified. 30

Management Information Systems and Inventory Management We operate various data processing systems to purchase, monitor and allocate inventory throughout our production facilities, enabling us to effectively manage inventory costs and consistently achieve a high annual inventory turnover rate. For the year ended December 31, 2000, our inventory turned more than five times. We use a computerized order entry system that enables customers to link their computer system to ours for direct electronic communication with respect to order entry, inventory status, work-in-process status, billing and payment. This service is designed to improve productivity for both customers and us. A number of key customers have taken advantage of this service, and we believe the availability of this service is becoming an important consideration in customers' purchasing decisions. In addition, we have linked our production equipment to our computer system to allow for the gathering of production data as each order is being processed. This information is stored in a database to be used as a basis for preparing cost estimates for future orders. This system enhances our ability to analyze costs on an ongoing basis and allows for expeditious response time on quotation requests. We continue to update and upgrade our proprietary and commercially available systems and computer hardware in order to maximize our efficiency and effectiveness. Suppliers and Raw Materials Steel and metal processing companies are required to maintain substantial inventories of raw materials in order to accommodate the short lead times and just-in-time delivery requirements of their customers. Accordingly, we generally maintain our inventory of raw materials at levels that we believe are sufficient to satisfy the anticipated needs of our customers based upon historic buying practices and market conditions. The primary raw material we process is flat-rolled steel purchased at regular intervals on an as-needed basis from numerous suppliers located primarily in North America. In 2000, we purchased $1 million or more of metals from 39 suppliers, of which only eight were located in non-NAFTA countries. We do not have long-term commitments with any of our suppliers. Technical Services We employ a staff of engineers and other technical personnel and maintain fully equipped, modern laboratories to support our operations. These facilities enable us to verify, analyze and document the physical, chemical, metallurgical and mechanical properties of our raw materials, finished products and services. Technical service personnel also work in connection with our sales force to determine the types of flat-rolled steel required for the needs of our customers. Our technical services personnel provide a wide range of support services in connection with the manufacture of our building and construction products. Our engineering staff employs a range of CAD/CAM programs to design highly specialized and technically precise products, including truss hangers, hurricane enclosures and custom designed building products. All of our heat-treating facilities employ full-time metallurgists and process engineers. We also maintain laboratories equipped with advanced instrumentation at each of our heat-treating facilities. Sales and Marketing We have a multifaceted sales and marketing program for our products and services. Our outside sales personnel travel throughout a geographic region to maintain and expand relationships with current customers and cultivate new accounts. We also have inside sales personnel, who remain at our facilities to service and support existing and prospective customers. All of our sales people receive incentive compensation based on profitability and performance. 31

We support our sales and marketing activities through participation in leading trade shows, such as the National Hardware Show. We also advertise our products in a number of trade publications and through co-op programs with our customers. We also use the Internet to support and enhance our sales and marketing activities. We operate web sites that provide information on products and services, pricing and other essential pieces of information. We are continually evaluating new technologies in an effort to improve service, lower costs and increase sales. Customers and Distribution We have approximately 10,000 customers located throughout the United States, Canada and Mexico, principally in the automotive, automotive supply, building and construction, steel, machinery and fastener industries. Major customers include automobile manufacturers and suppliers, building and construction product distributors and commercial and residential contractors. No single customer accounted for 10% or more of our consolidated net sales for 1998, 1999 or 2000. During 1998, 1999 and 2000, one customer of our Processed Steel Products segment accounted for 10.1%, 12.5% and 10.5%, respectively, of this segment's net sales. During 1998, 1999 and 2000, one customer of our Building Products segment accounted for 15.3%, 16.8% and 16.3% respectively, of this segment's net sales. With respect to our Heat Treating segment, one customer accounted for 12.0% of this segment's net sales in 1998 and another customer accounted for 11.6% in 2000. No other single customer accounted for more than 10% of any segment's net sales during this three year period. We manufacture products exclusively to customer order rather than for inventory, except for building and construction products. Although we negotiate annual sales orders with a majority of our customers, these orders are subject to customer confirmation as to product amounts and delivery dates. Competition The steel processing market is highly competitive. We compete with a small number of other steel processors, some of which also focus on fully processed, high value-added steel products, on the basis of the precision and range of achievable tolerances, quality, price, inventory availability and the ability to meet delivery schedules dictated by customers. We also compete with numerous suppliers of building and construction products, as well as service centers, a small number of regional commercial heat-treaters and steel strapping manufacturers, on the basis of quality, price, products, range of sizes offered and the ability to meet delivery schedules dictated by customers. Employees At September 30, 2001, we employed approximately 3,500 people, of whom approximately 500 were represented under five separate collective bargaining agreements which terminate at various times between July 1, 2002 and July 27, 2005. We have never experienced a work stoppage at our existing facilities. We believe that our relationship with our employees is good. Over 80% of our employees participate in performance-based incentive compensation programs. We are committed to such programs because we believe they motivate employees to enhance our profitability. Backlog Because of the nature of our products and the short lead time order cycle, we do not believe that backlog is a significant factor in our business. 32

Properties We maintain our corporate headquarters in Buffalo, New York and conduct our processing, manufacturing and distribution operations at 54 facilities located in 20 states and Mexico. We believe that our properties have been adequately maintained, are in generally good condition and are suitable for our business as presently conducted. We believe our existing facilities provide sufficient production capacity for our present needs and for our anticipated needs in the foreseeable future. We also believe that upon the expiration of our current leases, we either will be able to secure renewal terms or enter into leases for alternative locations at market terms. Governmental Regulation Our processing centers and manufacturing facilities are subject to many federal, state, local and foreign laws and regulations relating to the protection of the environment. Some of our operations require environmental permits and controls to prevent and reduce air and water pollution which are subject to modification, renewal and revocation by government authorities. We believe that we are in material compliance with all environmental laws, regulations and permits, and we do not anticipate any material expenditures to meet current or pending environmental requirements. However, we could incur operating costs or capital expenditures in complying with future or more stringent environmental requirements or with current requirements if they are applied to our facilities in a way we do not anticipate. Since 1993, we have acquired 15 new businesses with a broad variety of product lines and services. As a result of this expansion and our use of a greater variety of raw materials, chemicals and equipment, we have become subject to a wider set of environmental laws and regulations. In 1995, we retained an environmental consulting firm to assist us in evaluating the regulatory compliance and permit status of each business and in developing a comprehensive environmental management and audit program at the corporate level. We are continuing to develop and implement environmental compliance and management systems. Our operations are also governed by many other laws and regulations, including those relating to workplace safety and worker health, principally the Occupational Safety and Health Act and regulations thereunder which, among other requirements, establish noise and dust standards. We believe that we are in material compliance with these laws and regulations and do not believe that future compliance with such laws and regulations will have a material adverse effect on our results of operations or financial condition. Legal Proceedings From time to time, we are named a defendant in legal actions arising out of the normal course of business. We are not a party to any pending legal proceeding the resolution of which we believe will have a material adverse effect on our results of operations or financial condition or to any other pending legal proceedings other than ordinary, routine litigation incidental to our business. We maintain liability insurance against risks arising out of the normal course of business. 33

DESCRIPTION OF CAPITAL STOCK Our authorized capital stock consists of 50 million shares of common stock and 10 million shares of undesignated preferred stock, $.01 par value per share. As of September 30, 2001, there were 12,598,499 shares of common stock issued and outstanding. Upon completion of this offering, there will be 15,098,499 shares of common stock issued and outstanding, assuming no exercise of the underwriters' over-allotment option. There are no shares of our preferred stock outstanding. Common Stock Voting Rights. Each share of common stock is entitled to one vote on all matters submitted to a vote of our stockholders, including the election of directors. There is no cumulative voting. Therefore, the holders of a majority of the shares of common stock voted in an election of directors can elect all of the directors then standing for election, subject to any rights of the holders of any outstanding preferred stock. Dividends, Distributions and Stock Splits. Holders of shares of common stock are entitled to receive dividends, if, as and when such dividends are declared by our board of directors out of assets legally available therefor after payment of dividends required to be paid on shares of outstanding preferred stock. Liquidation. In the event of any dissolution, liquidation or winding up of our affairs, whether voluntary or involuntary, after payment of our debts and other liabilities and making provision for the holders of outstanding preferred stock, if any, our remaining assets will be distributed ratably among the holders of our common stock. Preferred Stock Our board of directors has the authority to issue preferred stock in one or more series and to establish the rights and restrictions granted to or imposed on any unissued shares of preferred stock and to fix the number of shares constituting any series without any further vote or action by our stockholders. Our board of directors has the authority, without approval of our stockholders, to issue preferred stock that has voting and conversion rights superior to our common stock, which could have the effect of deterring, delaying or preventing a change in control. We currently have no plans to issue any shares of preferred stock. Certain Provisions of the Certificate of Incorporation and By-Laws Our certificate of incorporation contains certain provisions permitted under the Delaware General Corporation Law relating to the liability of our directors. These provisions eliminate a director's personal liability to us or our stockholders for monetary damages resulting from a breach of fiduciary duty, except in certain circumstances involving certain wrongful acts, including: . for any breach of the director's duty of loyalty to us or our stockholders; . for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; . under Section 174 of the Delaware General Corporation Law; or . for any transaction in which the director derives an improper benefit. These provisions do not eliminate our right or those of any of our stockholders to seek non-monetary relief, such as an injunction or rescission, in the event of a breach of a director's fiduciary duty. These provisions will not alter a director's liability under federal securities laws. Our by-laws also contain certain provisions indemnifying our directors and officers to the fullest extent permitted by the Delaware General Corporation Law. We believe that these provisions are necessary to attract and retain qualified individuals to serve as directors and officers. 39

Our certificate of incorporation also contains provisions dividing our board of directors into three classes serving staggered three-year terms. Our directors can be removed from office only for cause and only by the affirmative vote of the holders of a majority of the voting power of the then outstanding shares of our capital stock entitled to vote generally in the election of directors (the "Voting Stock"), voting together as a single class. Vacancies on our board of directors may only be filled by the remaining directors and not by our stockholders. Our by-laws establish an advance notice procedure with regard to the nomination, other than by or at the direction of the board of directors, of candidates for election as directors and with regard to certain matters to be brought before an annual meeting of our stockholders. In general, notice must be received by us not less than 60 nor more than 90 days prior to the date of the prior year's annual meeting and must contain certain specified information concerning the person to be nominated or the matter to be brought before the meeting and concerning the stockholder submitting the proposal. Annual meetings of our stockholders shall be held to elect our board of directors and to transact such other business as may be properly brought before the meeting. Special meetings of our stockholders may be called only by our Chairman of the Board, President or a majority of our board of directors. Our certificate of incorporation provides that any action required or permitted to be taken by our stockholders may be effected only at a duly called annual or special meeting of our stockholders and may not be effected by written consent of our stockholders. Our certificate of incorporation also provides that certain mergers, sales of assets, issuances of securities, liquidations or dissolutions, reclassifications or recapitalizations involving Interested Stockholders must be approved by holders of at least 80% of the outstanding Voting Stock, unless such transactions are approved by a majority of the Disinterested Directors (as defined in our certificate of incorporation) or certain minimum price, form of consideration and procedural requirements are satisfied. An Interested Stockholder is defined as a holder of stock representing 20% or more of the shares of Voting Stock then outstanding. Our certificate of incorporation further provides that the affirmative vote of the holders of 80% of the total votes eligible to be cast in the election of directors is required to amend, alter, change or repeal such provisions. The requirement of such a super-majority vote could enable a minority of our stockholders to exercise veto powers over such amendments, alterations, changes or repeals. Delaware Anti-Takeover Law Our company is a Delaware corporation subject to the provisions of Section 203 of the Delaware General Corporation Law, an anti-takeover law. Generally, this statute prohibits a publicly-held Delaware corporation from engaging in a business combination with an "interested stockholder" for a period of three years after the date of the transaction in which such person became an interested stockholder, unless the business combination is approved in a prescribed manner. A "business combination" includes a merger, asset sale or other transaction resulting in a financial benefit to the stockholder. For purposes of Section 203, an "interested stockholder" is defined to include any person that is: . the owner of 15% or more of the outstanding voting stock of a corporation; . an affiliate or associate of a corporation and was the owner of 15% or more of the outstanding voting stock of the corporation at any time within three years immediately prior to the date on which it is sought to be determined whether such person is an interested stockholder; and . an affiliate or associate of the persons described above. Stockholders may, by adopting an amendment to the corporation's certificate of incorporation or by-laws, elect for the corporation not to be governed by Section 203, effective 12 months after adoption. Neither our certificate of incorporation nor our by-laws exempt us from the restrictions imposed under Section 203. We anticipate that the provisions of Section 203 may encourage parties interested in acquiring us to negotiate in 40

advance with our board of directors because the stockholder approval requirement would be avoided if a majority of the directors then in office approve either the business combination or the transaction that results in the stockholder becoming an interested stockholder. Transfer Agent and Registrar The Transfer Agent and Registrar for our common stock is American Stock Transfer & Trust Company, New York, New York. 41

UNDERWRITING Salomon Smith Barney Inc. is acting as representative of the underwriters named below. Subject to the terms and conditions stated in the underwriting agreement dated the date of this prospectus, each underwriter named below has agreed to purchase, and we and the selling stockholders have agreed to sell to that underwriter, the number of shares set forth opposite the underwriter's name. Number Underwriter of shares ----------- --------- Salomon Smith Barney Inc................................. McDonald Investments Inc................................. --------- Total................................................. 3,000,000 ========= The underwriting agreement provides that the obligations of the underwriters to purchase the shares included in this offering are subject to approval of legal matters by counsel and to other conditions. The underwriters are obligated to purchase all the shares (other than those covered by the over-allotment option described below) if they purchase any of the shares. The underwriters propose to offer some of the shares directly to the public at the public offering price set forth on the cover page of this prospectus and some of the shares to dealers at the public offering price less a concession not to exceed $ per share. The underwriters may allow, and dealers may reallow, a concession not to exceed $ per share on sales to other dealers. If all of the shares are not sold at the initial offering price, the representatives may change the public offering price and the other selling terms. We have granted to the underwriters an option, exercisable for 30 days from the date of this prospectus, to purchase up to 450,000 additional shares of common stock at the public offering price less the underwriting discount. The underwriters may exercise the option solely for the purpose of covering over-allotments, if any, in connection with this offering. To the extent the option is exercised, each underwriter must purchase a number of additional shares approximately proportionate to that underwriter's initial purchase commitment. We, our officers and directors, and the selling stockholders have agreed that, for a period of 90 days from the date of this prospectus, we and they will not, without the prior written consent of Salomon Smith Barney, dispose of or hedge any shares of our common stock or any securities convertible into or exchangeable for our common stock, except that our officers and directors and the selling stockholders may dispose of such shares as bona fide gifts. Salomon Smith Barney in its sole discretion may release any of the securities subject to these lock-up agreements at any time without notice. The common stock is quoted on the Nasdaq National Market under the symbol "ROCK." The following table shows the underwriting discounts and commissions that we and the selling stockholders are to pay to the underwriters in connection with this offering. These amounts are shown assuming both no exercise and full exercise of the underwriters' option to purchase additional shares of common stock.

In connection with the offering, Salomon Smith Barney, on behalf of the underwriters, may purchase and sell shares of common stock in the open market. These transactions may include short sales, syndicate covering transactions and stabilizing transactions. Short sales involve syndicate sales of common stock in excess of the number of shares to be purchased by the underwriters in the offering, which creates a syndicate short position. "Covered" short sales are sales of shares made in an amount up to the number of shares represented by the underwriters' over-allotment option. In determining the source of shares to close out the covered syndicate short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the over-allotment option. Transactions to close out the covered syndicate short involve either purchases of the common stock in the open market after the distribution has been completed or the exercise of the over-allotment option. The underwriters may also make "naked" short sales of shares in excess of the over-allotment option. The underwriters must close out any naked short position by purchasing shares of common stock in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the shares in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of bids for or purchases of shares in the open market while the offering is in progress. The underwriters also may impose a penalty bid. Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when Salomon Smith Barney repurchases shares originally sold by that syndicate member in order to cover syndicate short positions or make stabilizing purchases. Any of these activities may have the effect of preventing or retarding a decline in the market price of the common stock. They may also cause the price of the common stock to be higher than the price that would otherwise exist in the open market in the absence of these transactions. The underwriters may conduct these transactions on the Nasdaq National Market or in the over-the-counter market, or otherwise. If the underwriters commence any of these transactions, they may discontinue them at any time. We and the selling stockholders estimate that our respective portions of the total expenses of this offering will be $ and $ . Under rule 2710(c)(8) of the Conduct Rules of the National Association of Securities Dealers, Inc., special considerations apply to a public offering of securities where more than 10% of the net proceeds thereof will be paid to members of the NASD that are participating in the offering, or persons affiliated or associated with such members. Certain of the underwriters or their respective affiliates have lent money to the company under existing credit facilities. In the event more than 10% of the proceeds of the offering will be used to repay such money lent by any underwriter or its affiliates, the offering will be conducted in conformity with Rule 2710(c)(8). The underwriters have performed investment banking and advisory services for us from time to time for which they have received customary fees and expenses. The underwriters may, from time to time, engage in transactions with and perform services for us in the ordinary course of their business. A prospectus in electronic format may be made available on the web sites maintained by one or more of the underwriters. The representatives may agree to allocate a number of shares to underwriters for sale to their online brokerage account holders. The representatives will allocate shares to underwriters that may make Internet distributions on the same basis as other allocations. In addition, shares may be sold by the underwriters to securities dealers who resell shares to online brokerage account holders.

GIBRALTAR STEEL CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation The consolidated financial statements include the accounts of Gibraltar Steel Corporation and subsidiaries (the Company). Significant intercompany accounts and transactions have been eliminated. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Cash and Cash Equivalents Cash and cash equivalents include cash on hand, checking accounts and all highly liquid investments with a maturity of three months or less. Inventories Inventories are valued at the lower of cost or market. Cost is determined using the first-in, first-out method. Property, Plant and Equipment Property, plant and equipment are stated at cost and depreciated over their estimated useful lives using the straight-line method. Accelerated methods are used for income tax purposes. Interest is capitalized in connection with construction of qualified assets. Under this policy, interest of $552,000, $357,000 and $404,000 was capitalized in 2000, 1999 and 1998, respectively. Goodwill Goodwill is amortized over 35 years. Amortization expense related to goodwill was $3,710,000, $2,647,000 and $1,949,000 in 2000, 1999, and 1998, respectively. Accumulated amortization was $9,961,000 and $6,251,000 at December 31, 2000 and 1999. Shareholders' Equity In 1999 and 1998, the Company issued 20,572 and 11,000, respectively, of its common shares as contributions to its profit-sharing plans. The Company did not contribute any of its shares to its profit-sharing plans during 2000. During 2000 and 1999, the Company declared dividends of $1,447,000 and $1,568,000, respectively, of which $377,000 and $315,000 are accrued at December 31, 2000 and 1999, respectively. During 2000, the Company purchased 12,572 shares of its outstanding common stock at a cost of $14.38 per share. The Company did not repurchase any shares of its common stock in prior years. Interest Rate Exchange Agreements Interest rate swap agreements, which are used by the Company in the management of interest rate risk, are accounted for on an accrual basis. Amounts to be paid or received under interest rate swap agreements are recognized as interest expense or income in the periods in which they accrue. Swaps are not used for trading purposes. Income Taxes The financial statements of the Company have been prepared using the asset and liability approach in accounting for income taxes which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of other assets and liabilities. F-7

GIBRALTAR STEEL CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) Earnings Per Share Basic net income per share equals net income divided by the weighted average shares outstanding during the year. The computation of diluted net income per share includes all dilutive common stock equivalents in the weighted average shares outstanding. 2. ACQUISITIONS On July 17, 2000, the Company purchased all the outstanding capital stock of Milcor Limited Partnership (Milcor) for approximately $43 million in cash.

On August 1, 1999, the Company purchased the assets and business of Hi-Temp Incorporated (Hi-Temp) for approximately $24 million in cash.

On July 1, 1999, the Company purchased all the outstanding capital stock of K & W Metal Fabricators, Inc. d/b/a Weather Guard Building Products (Weather Guard) for approximately $7 million in cash. Weather Guard manufactures a full line of metal building products, including rain-carrying systems, metal roofing and roofing accessories, for industrial, commercial and residential applications. These acquisitions have been accounted for under the purchase method with the results of their operations consolidated with the Company's results of operations from the respective acquisition dates. The aggregate excess of the purchase prices of these acquisitions over the fair market values of the net assets of the acquired companies is being amortized over 35 years from the acquisition dates using the straight-line method. The following information presents the pro forma consolidated condensed results of operations as if the acquisitions had occurred on January 1, 1999. The pro forma amounts may not be indicative of the results that actually would have been achieved had the acquisitions occurred as of January 1, 1999 and are not necessarily indicative of future results of the combined companies.

Total cash paid for interest in the years ended December 31, 2000, 1999 and 1998 was $19,935,000, $13,357,000 and $11,257,000, respectively. 8.

The effect of a 1% increase or decrease in the annual medical inflation rate would increase or decrease the accumulated post-retirement benefit obligation at December 31, 2000 by approximately $312,000 and $266,000, respectively, and increase or decrease the annual service and interest costs by approximately $38,000. One of the Company's subsidiaries also provides post-retirement health care benefits to its unionized employees through contributions to a multi-employer health care plan. F-11

Accordingly, no compensation cost has been recognized for the option plans as stock options granted under these plans have an exercise price equal to 100% of the market price on the date of grant. If the compensation cost for these plans had been determined based on the fair value at the grant dates for awards consistent with the method of FAS No. 123, the unaudited pro forma effect on the years ended December 31, 2000 and 1999 is as follows: As Reported Pro Forma As Reported Pro Forma 2000 2000 1999 1999 ----------- ----------- ----------- ----------- Net income..................... $24,365,000 $23,073,000 $25,008,000 $23,566,000 Net income per share--Basic.... $1.94 $1.83 $1.99 $1.88 The Black-Scholes option-pricing model was used to estimate the fair value of the options granted on the date of grant.

Since the inception of this plan, 59,000 common shares have been awarded. 14. COMMITMENTS AND CONTINGENCIES The Company is a party to certain claims and legal actions generally incidental to its business. Management does not believe that the outcome of these actions, which is not clearly determinable at the present time, would significantly affect the Company's financial condition or results of operations. 15. SUBSEQUENT EVENT In February 2001, the Company purchased all the outstanding capital stock of Pennsylvania Industrial Heat Treaters, Inc. (PIHT) for approximately $11 million, net of cash. PIHT provides metallurgical heat-treating services and specializes in heat-treating powdered metal parts.

GIBRALTAR STEEL CORPORATION NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Continued) (Unaudited) 4. EARNINGS PER SHARE Basic net income per share equals net income divided by the weighted average shares outstanding for the nine months ended September 30, 2001 and 2000. The computation of diluted net income per share includes all dilutive common stock equivalents in the weighted average shares outstanding. Options to purchase 1,088,742 shares of the Company's common stock are outstanding as of September 30, 2001 and are exercisable at prices ranging from $10.00 to $22.50 per share. Included in diluted shares are common stock equivalents relating to options of 180,425 and 120,064 for the nine-month periods ended September 30, 2001 and 2000, respectively. 5. ACQUISITIONS On February 13, 2001, the Company purchased all the outstanding capital stock of Pennsylvania Industrial Heat Treaters, Inc. (PIHT) for approximately $11 million, net of cash acquired. PIHT provides metallurgical heat-treating services and specializes in heat-treating powdered metal parts. On July 17, 2000, the Company purchased all the outstanding capital stock of Milcor Limited Partnership (Milcor) for approximately $43 million in cash. Milcor manufactures a complete line of metal building products, including registers, vents, bath cabinets, access doors, roof hatches and telescoping doors. These acquisitions have been accounted for under the purchase method with the results of their operations consolidated with the Company's results of operations from the respective acquisition dates. The aggregate excess of the purchase prices of these acquisitions over the fair market values of the net assets of the acquired companies is being amortized over 35 years from the acquisition dates using the straight-line method. The following information presents the pro forma consolidated condensed results of operations as if the acquisitions had occurred on January 1, 2000. The pro forma amounts may not be indicative of the results that actually would have been achieved had the acquisitions occurred as of January 1, 2000 and are not necessarily indicative of future results of the combined companies.

Indemnification of Directors and Officers Under Section 145(a) of the General Corporation Law of Delaware, we may indemnify any of our officers or directors in any action other than actions by or in the right of our company, whether civil, criminal, administrative or investigative, if such director or officer acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of our company, and, with respect to any criminal action or proceedings if such director or officer has no reasonable cause to believe his conduct was unlawful. Under Section 145(b), we may indemnify any of our officers or directors in any action by or in the right of our company against expenses actually and reasonably incurred by him in the defense or settlement of such action if such officer or director acted in good faith and in a manner he reasonably believed to be in or not opposed to our best interest, except where such director or officer shall have been adjudged to be liable for negligence or misconduct in the performance of his duty to us, unless, on application, the Court of Chancery or the court in which such action or suit was brought shall determine that, despite the adjudication of liability, such person in view of all the circumstances is fairly and reasonably entitled to indemnity for such expenses as the court shall deem proper. Section 145(c) provides for mandatory indemnification of officers or directors who have been successful on the merits or otherwise in the defense of any action, suit or proceeding referred to in subsections (a) and (b). Section 145(d) authorizes indemnification under subsections (a) and (b) in specific cases if approved by our board of directors or stockholders upon a finding that the officer or director in question has met the requisite statutory standards of conduct. Section 145(g) empowers us to purchase insurance coverage for any director, officer, employee or agent against any liability incurred by him in his capacity as such, whether or not we would have the power to indemnify him under the provisions of the Delaware General Corporation Law. The foregoing is only a summary of the described sections of the Delaware General Corporation Law and is qualified in its entirety by reference to such sections. Our certificate of incorporation provides that we shall indemnify each of our officers and directors to the fullest extent permitted by applicable law. Our certificate of incorporation also provides that, to the fullest extent permitted by the Delaware General Corporation Law, our directors shall not be liable to us or our stockholders for monetary damages for breach of fiduciary duty as a director.

Item 17. Undertakings (a) Insofar as indemnification for liabilities arising under the Securities Act of 1933 (the ''Act'') may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. (b) We hereby undertake that: (i) For purposes of determining any liability under the Act, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430(A) and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Act shall be deemed to be part of this registration statement as of the time it was declared effective; (ii) For the purpose of determining any liability under the Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; and (iii) For the purpose of determining any liability under the Act, each filing of the registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
