         The accompanying condensed consolidated financial statements as of
         September 30, 1998 and 1997 have been prepared by the Company without

         flows at September 30, 1998 and 1997 have been included.
         
         Certain information and footnote disclosures including significant
         accounting policies normally included in financial statements

         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,
         1998 and 1997.  The computation of diluted net income per share
         includes all dilutive common stock equivalents in the weighted
         average shares outstanding. The reconciliation between basic and
         diluted earnings per share is as follows:
         
                                      Basic      Basic     Diluted     Diluted

             1998     $15,018,000   12,446,209   $1.21   12,639,655     $1.19
             1997     $12,930,000   12,340,900   $1.05   12,584,083     $1.03
         
         
         Included in diluted shares are common stock equivalents relating to
         options of 193,446 and 243,183 for 1998 and 1997, respectively.
         
         
         
         5.  ACQUISITIONS
         
         On June 1, 1998, the Company purchased all the outstanding common
         stock of United Steel Products Company (USP) for approximately $24
         million in cash.  USP designs and manufacturers lumber connector
         products for the wholesale market and plastic molded products for
         component manufacturers.
         
         On April 1, 1998, the Company purchased the assets and business of
         Appleton Supply Co., Inc. (Appleton) for approximately $28 million in
         cash.  Appleton manufactures louvers, roof edging, soffitts and other
         metal building products for wholesale distribution.
         

         

                                        
                                        
                                        
                                        
                                     7 of 13
         
        On March 1, 1998, the Company purchased the assets and business of The
        Solar Group (Solar) for approximately $35 million in cash.  Solar
        manufactures a line of construction products as well as a complete line
        of mailboxes, primarily manufactured with galvanized steel.
        
        On January 31, 1997, the Company purchased all of the outstanding
        capital stock of Southeastern Metals Manufacturing Company, Inc.
        (SEMCO) for approximately $25 million in cash. SEMCO manufactures a
        wide array of metal products for the residential and commercial
        construction markets.

         These acquisitions have been accounted for under the purchase method.
         Results of operations of USP, Appleton, Solar and SEMCO have been
         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 approximately $58 million and 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, 1997.  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, 1997 and are not necessarily
         indicative of future results of the combined companies.

        On October 1, 1998, the Company purchased all the outstanding capital
        stock of Harbor Metal Treating Co. and its affiliates (collectively,
        Harbor Metal) for $13.5 million in cash.  The results of operations
        of Harbor Metal will be consolidated with the Company's results of
        operations from the acquisition date for the quarter ending December
        31, 1998.

         Item 2.  Management's Discussion and Analysis of Financial Condition
                  and Results of Operations
         
         
         Results of Operations

         Net sales of $152.6 million for the third quarter ended September 30,
         1998 increased 33.6% from sales of $114.2 million for the prior
         year's third quarter. Net sales of $413.9 million for the nine months
         ended September 30, 1998 increased 21.1% from net sales of $341.7
         million for the same period of 1997.  These increases resulted from
         including net sales of Solar (acquired March 1, 1998), Appleton
         (acquired April 1, 1998) and USP (acquired June 1, 1998) and sales
         growth at existing operations despite the impact of decreased sales
         due to a 54 day strike at General Motors, which was settled in late
         July 1998.
         
         Cost of sales as a percentage of net sales decreased to 81.9% for
         both the third quarter and the first nine months of 1998.  Gross
         profit increased to 18.1% for both periods in 1998 from 15.9% and
         16.6% for the comparable periods in 1997.  This increase is primarily
         due to higher margins at SEMCO, Solar, Appleton and USP, which have
         historically generated higher margins than the Company's other
         products and services, and due to lower raw material costs at
         existing operations.
         
         Selling, general and administrative expenses as a percentage of net
         sales increased to 10.3% and 10.2% for the third quarter and nine
         months ended September 30, 1998, respectively, from 9.2% and 9.1% for
         the same periods of 1997.  These increases were primarily due to
         higher costs as a percentage of sales attributable to Solar, Appleton
         and USP and performance based compensation linked to the Company's
         sales and profitability.
         
         Interest expense for the third quarter and nine months ended
         September 30, 1998 increased by $2.0 million and $3.8 million,
         respectively, from the same periods in 1997 primarily due to higher
         borrowings to finance the Solar, Appleton and USP acquisitions and
         capital expenditures.
         
         As a result of the above, income before taxes increased by $2.3
         million and $3.4 million for the third quarter and nine months ended
         September 30, 1998 from the same periods of 1997.
         
         Income taxes for the third quarter and nine months ended September
         30, 1998 approximated $3.4 million and $10.0 million, respectively,
         and were based on a 40.0% effective tax rate for both periods
         compared to an effective tax rate of 40.0% and 40.4%, respectively,
         for the same periods in 1997.
         
         
         Liquidity and Capital Resources
         
         During the first nine months of 1998, the Company increased its
         working capital to $125.6 million.  Additionally, shareholders'
         equity increased to $155.4 million at September 30, 1998.
         
         The Company's principal capital requirements are to fund its
         operations, including working capital, the purchase and funding of
         improvements to its facilities, machinery and equipment and to fund
         acquisitions.
         
         
         
                                     9 of 13
         
         Net income of $15.0 million and depreciation and amortization of $9.4
         million combined with an increase in accounts payable and accrued
         expenses (net of acquisition) of $16.1 million to provide cash of
         $40.5 million.  Increases in inventory and accounts receivable of
         approximately $37.2 million in aggregate, necessary to service
         increased sales levels, primarily resulted in net cash provided by
         operations of approximately $2.5 million.
         
         Capital expenditures of $16.8 million and the acquisition of Solar,
         Appleton and USP for cash totalling approximately $86.8 million were
         primarily funded by net borrowings of $100.8 million under the
         Company's credit facility and cash provided by operations.
         
         At September 30, 1998 the Company's aggregate credit facilities
         available approximated $239 million with borrowings of approximately
         $189 million with an additional availability of approximately $50
         million.
         
         The Company used approximately $13.5 million of the facility on
         October 1, 1998 for the acquisition of Harbor Metal.
         
         The Company believes that availability of funds under its credit
         facilities together with cash generated from operations will be
         sufficient to provide the Company with the liquidity and capital
         resources necessary to support its existing operations.  The Company
         also believes it has the financial capability to increase its long-
         term borrowing capacity due to changes in capital requirements.
         
         
         Impact of Year 2000
         
         The Year 2000 issue concerns the inability of some computer hardware
         and software to distinguish between the year 1900 and the year 2000.
         If not corrected, computer applications could fail or create erroneous
         results.
         
         The Company is conducting a detailed assessment of all of its
         information technology and non-information technology hardware and
         software with regard to Year 2000 issues.  The Company's plan to ensure
         that its systems are Year 2000 ready is comprised of: cataloging all
         processes and systems which may have a date-related component and
         identifying those which are not Year 2000 ready; correcting or
         replacing those systems which are not Year 2000 ready; and testing the
         corrected or replaced processes and systems to insure that they will,
         in fact, operate as desired according to Year 2000 requirements.  The
         Company is in various stages of its Year 2000 readiness process at each
         of its subsidiaries and expects to complete testing of the corrected or
         replaced systems and be fully Year 2000 ready by July 1999.  In
         addition, the Company is working with its major customers and major
         vendors, including raw material suppliers and utility companies, to
         assess their internal state of Year 2000 readiness.  These customer and
         vendor responses are evaluated for any possible risk to, or effect on,

         Costs specifically associated with modifying internal use software for
         Year 2000 readiness are expensed as incurred but have not been, and are
         not expected to be, material to the Company's net income.  Costs of
         replacing some of the Company's systems with Year 2000 ready systems
         have been capitalized as these new systems were acquired for business
         reasons and not to remediate Year 2000 problems, if any, in the former
         systems.
         
         Based upon the results of Year 2000 readiness efforts underway, the
         Company believes that all critical information and non-information
         technology systems and processes will be Year 2000 ready and allow the
         Company to continue operations beyond the Year 2000 without a material
         impact on its results of operations or financial position.  However,
         unanticipated problems which may be identified in the ongoing Year 2000
         readiness process could result in an undetermined financial risk.
         Contingency plans to counter these unanticipated problems are being
         developed as part of the ongoing Year 2000 readiness process.
         
                                        
         Recent Accounting Pronouncement
         
         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) which
         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.  Implementation of FAS No. 133 is required for fiscal
         2000.  The Company does not believe that FAS No. 133 will have a
         material impact on its earnings or other comprehensive income.
