EXHIBIT INDEX 99.1 Press Release of the Company dated February 3, 2004

                                                                    Exhibit 99.1

         Gibraltar Reports Record Sales and Earnings in 2003;
                Sales Increased 18 % to $758 Million,
                Net Income Grew by 13% to $27 Million

    BUFFALO, N.Y.--(BUSINESS WIRE)--Feb. 3, 2004--Gibraltar (Nasdaq:
ROCK) today reported record sales and earnings for the quarter and
year ended December 31, 2003. The Company also said that the steps it
took in 2003 to grow every part of its business and the successful
completion of its stock offering put it in an excellent position to
continue its sales and earnings growth.
    Sales of $185 million in the fourth quarter of 2003 were a
fourth-quarter record, and increased by approximately $29 million, or
19 percent, from $156 million in the fourth quarter of 2002. Best-ever
annual sales of $758 million in 2003 increased by approximately $113
million, or 18 percent, from $645 million in 2002.
    Net income of $5.8 million in the quarter ended December 31, 2003,
was a fourth-quarter record, and increased by approximately 24 percent
from $4.7 million in the fourth quarter of 2002. In 2003, full-year
net income of $27.0 million was the highest in the Company's history,
and increased by approximately 13 percent compared to $23.9 million in
2002.
    Earnings per share in the fourth quarter of 2003 were $.35, an
increase of 21 percent compared to $.29 per share in the fourth
quarter of 2002, on approximately 3 percent more weighted average
shares outstanding as a result of Gibraltar's successful completion of
its secondary stock offering of 3,000,000 shares in December 2003. In
2003, earnings per share increased to $1.66, from $1.54 in 2002, on
approximately 5 percent more weighted average shares outstanding as a
result of Gibraltar's secondary stock offerings in March 2002 and
December 2003.
    "In 2003, we generated record sales and earnings, successfully
completed our largest stock offering, and took steps that will help us
produce strong and sustained growth in our business in the future, in
spite of an economy that - even though it gained strength as the year
progressed - operated well below peak levels," said Brian J. Lipke,
Gibraltar's Chairman and Chief Executive Officer.
    "The immediately accretive acquisition of two building products
companies (Construction Metals on April 1 and Air Vent on May 1)
broadened our geographic reach, solidified our product offering, and
added approximately $100 million to our annual sales. We strengthened
our processed steel products operations through our recently announced
joint venture with Duferco Farrell, through which we acquired a 50
percent interest in their Strip Steel Division (which had 2003 sales
of approximately $55 million), putting us in a partnership with a
recognized leader in the international steel industry. And our
heat-treating operations finalized agreements with two major
automotive customers, which we believe will result in approximately
$75 million in new business over the next seven years," said Mr.
Lipke.
    "In December 2003, our common stock offering generated net
proceeds of approximately $70 million, and reduced our year-end net
debt-to-capitalization ratio to 35 percent (compared to approximately
51 percent at June 30, 2003, following the second-quarter acquisitions
of CMI and Air Vent). Additionally, in January 2004, the exercise by
the underwriters of their over-allotment added 214,625 shares (and
approximately $5 million) to the offering. This gives us increased
resources and the financial flexibility to enhance our strategic
growth and profitability. With approximately 4.5 million additional
shares in the public float, and many new investors, it also
significantly improved our stock's liquidity.
    "We appreciate the confidence expressed by so many new and
existing shareholders, which we believe is a testament to our
performance during our first decade as a public company, as we
generated record sales and earnings in eight of the last ten years,
and our sales grew at a compound annual growth rate (CAGR) of 16
percent, while our net income grew at a 14 percent CAGR. These results
clearly established Gibraltar as a top performer in its peer group
during that period.
    "The many steps we've taken over the past ten years to make
Gibraltar stronger, not just bigger, have extended our reach into many
of North America's fastest-growing geographic and steel-consuming
markets, broadened and diversified our customer base and business mix,
and continued to move more of our business into higher-margin areas
like heat treating and building products.
    "We now sell more than 5,000 manufactured end products. We believe
we are North America's largest manufacturer of both ventilation
products and mailboxes, and a leader in a number of other product
categories (including structural connectors and metal roofing). The
sale of these products - which now accounts for approximately 56
percent our revenues - has helped us drive our margins higher, and
stabilize them across a variety of operating environments. As a result
of the strategic growth in this part of our company, we now have the
'critical mass,' the national manufacturing, marketing, and
distribution capabilities to accelerate the growth of our building
products business.
    "Our ongoing efforts to control and cut costs, and our focus on
asset management, also continue to serve us well. We remain committed
to driving our gross and operating margins higher, and we are
continuing our efforts to generate improvements in our returns on
invested capital, assets, and equity," said Mr. Lipke.
    Looking ahead, Mr. Lipke said that Gibraltar expects to continue
its positive year-over-year quarterly sales and earnings comparisons
in the first quarter. Barring a significant change in business
conditions, the Company expects its first-quarter earnings per share
will be in the range of $.32 to $.35, compared to $.30 in the first
quarter of 2003, on approximately 20 percent more weighted average
shares outstanding (19.5 million versus 16.2 million) as a result of
its recent stock offering.
    "We continue to be optimistic as we look out at 2004, even if the
economy stays flat, due to the many growth initiatives we have in
place, most recently our January 1 acquisition of Renown Specialties
Company (which is a leading Canadian manufacturer and distributor of
construction hardware). As the economy continues to get stronger, it
will accelerate our progress," said Mr. Lipke.

    Gibraltar is one of North America's leading metal processors, a
manufacturer of more than 5,000 steel, other metal, and plastic
products, and North America's second-largest commercial heat treater.
The Company serves approximately 10,000 customers in a variety of
industries in all 50 states, Canada, and Mexico. It has approximately
3,800 employees and operates 69 facilities in 26 states, Canada, and
Mexico.

    Information contained in this release, other than historical
information, should be considered forward-looking, and may be subject
to a number of risk factors, including: the impact of changing steel
prices on the Company's results of operations; changing demand for the
Company's products; risks associated with the integration of
acquisitions; and changes in interest or tax rates.

    Gibraltar will review its fourth-quarter results and discuss its
outlook for 2004 during its quarterly conference call, which will be
held at 2 p.m. Eastern Time on February 4. Details of the call can be
found on Gibraltar's Web site, at www.gibraltar1.com.
