         1.  CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
         
         The accompanying condensed consolidated financial
         statements as of September 30, 1997 and 1996 have been
         prepared by the Company without audit.  In the opinion of
         management, all adjustments necessary to present fairly the
         financial position, results of operations and cash flows at
         September 30, 1997 and 1996 have been included.
         
         Certain information and footnote disclosures including
         significant accounting policies normally included in
         financial statements prepared in accordance with generally
         accepted accounting principles have been condensed or
         omitted.  It is suggested that these condensed financial
         statements be read in conjunction with the financial
         statements included in the Company's Annual Report to
         Shareholders for the year ended December 31, 1996.
         
         The results of operations for the nine month period ended
         September 30, 1997 are not necessarily indicative of the
         results to be expected for the full year.

         The changes in stockholders' equity consist of:

         Additional paid-in capital increased approximately $791,000
         through the exercise of stock options and approximately
         $667,000 through a realized tax benefit from the
         disposition of certain stock options.  This benefit also
         resulted in a corresponding decrease in current income
         taxes payable.
         
                                   
         4.  EARNINGS PER SHARE
         
         Net income per share for the three and nine months ended
         September 30, 1997 and 1996 was computed by dividing net
         income by the weighted average number of common shares
         outstanding.
         
         
         5.  ACQUISITIONS
         
        On February 14, 1996, the Company purchased all of the
        outstanding capital stock of Carolina Commercial Heat
        Treating, Inc. (CCHT) for approximately $25 million in cash.
        CCHT, headquartered in Charlotte, North Carolina, provides
        heat treating, brazing and related metal-processing services
        to a broad range of industries, including the automotive,
        hand tools, construction equipment and industrial machinery
        industries.
        
        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.


                                7 of 12

         
         These acquisitions have been accounted for under the
         purchase method. Results of operations of CCHT and SEMCO
         have been consolidated with the Company's results of
         operations from the respective acquisition dates. The
         excess of the aggregate purchase price over the fair market
         value of net assets of CCHT and SEMCO approximated $12
         million and $10 million, respectively, 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, 1996.  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, 1996 and are not necessarily
         indicative of future results of the combined companies.

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

         
         Net sales of $114.2 million for the third quarter ended
         September 30, 1997 increased 30% from sales of $88.0
         million for the prior year's third quarter. Net sales of
         $341.7 million for the nine months ended September 30, 1997
         increased 33% from net sales of $256.5 million for the same
         period of 1996.  These increases primarily resulted from
         including net sales of SEMCO (acquired January 31, 1997)
         and sales growth at existing operations.
         
         Cost of sales increased to 84.1% of net sales for the third
         quarter and to 83.4% for the first nine months of 1997.
         Gross profit decreased to 15.9% and 16.6% for the third
         quarter and the nine months ended September 30, 1997 from
         18.2% and 17.9% for the comparable periods in 1996.  This
         decrease is primarily due to higher raw material costs
         which were not fully passed through to customers, offset
         partially by the inclusion of SEMCO's results.  SEMCO's
         sales historically have generated higher margins than the
         Company's other products and services.
         
         Selling, general and administrative expenses as a
         percentage of net sales increased to 9.2% and 9.1% for the
         third quarter and nine months ended September 30, 1997,
         respectively, from 8.8% for the same periods of 1996.
         These increases were primarily due to higher costs as a
         percentage of sales attributable to SEMCO and performance
         based compensationy.
         
         Interest expense increased by $.5 million for the quarter
         and $.7 million for the nine months ended September 30,
         1997 primarily due to higher average borrowings as a result
         of the SEMCO acquisition.
         
         As a result of the above, income before taxes decreased by
         $1.1 million and increased $1.7 million for the quarter
         and nine months ended September 30, 1997.
         
         Income taxes for the nine months ended September 30, 1997
         approximated $8.8 million and were based on a 40.4%
         effective tax rate for 1997 compared to an effective tax
         rate of 40.5% for the same period in 1996.

         Liquidity and Capital Resources
         
         During the first nine months of 1997, the Company increased
         its working capital to $93.3 million.  Additionally,
         shareholders' equity increased to $136.4 million at
         September 30, 1997.
         
         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.
         
         Net income of $12.9 million and depreciation and
         amortization of $6.2 million combined with a decrease in
         inventory (net of acquisitions) of $5.6 million to provide
         cash of $24.7 million.  This was partially offset by an
         increase in accounts receivable of $8.8 million, to service
         increased sales levels, and a decrease in accounts payable
         and accrued expenses of $2.2 million. The resulting net
         cash provided by operations of $13.1 million combined with
         an additional $28.3 million in net cash provided by
         financing activities funded the $26.5 million used for
         acquisitions and $17.7 million for capital expenditures.
         
         During September 1997, the Company increased its bank
         credit facility to $185 million which expires in November
         2002.  The facility was also changed to an unsecured basis.
         At September 30, 1997, the Company's aggregate credit
         facilities available approximated $190 million with
         borrowings of approximately $91 million and an additional
         availability of approximately $99 million.
         
         The Company believes that availability under its credit
         facilities together with funds generated from operations
         will be sufficient to provide the Company with the
         liquidity and capital resources necessary to support its
         operations and anticipated capital expenditures for the
         next twelve months.
