EXPLANATORY NOTE

We are filing this Amendment No. 1 (this Amendment) to our Annual Report on Form 10-K for the fiscal year ended
December 31, 2010, filed with the Securities and Exchange Commission (the SEC) on March 16, 2011 (the Original Report), for the sole purpose of disclosing managements annual report on internal control over
financial reporting under Item 9A of Part II of Form 10-K. This Amendment amends and restates in its entirety Item 9A of the Original Report. Except as set forth above, we have not changed or updated other information included in the
Original Report. This Amendment does not reflect events occurring after the date of the Original Report or modify or update any of the other disclosures contained therein in any way other than as required to reflect the amendments discussed above.
Accordingly, this Amendment should be read in conjunction with the Original Report and the Companys other filings with the SEC.

PART II



|ITEM 9A. | CONTROLS AND PROCEDURES
|-------- | -----------------------

Evaluation of Disclosure Controls and Procedures

As of December 31, 2010, an evaluation was carried out under the supervision and with the participation of our management, including the President and Chief Executive Officer and the Chief Financial
Officer, of the effectiveness of our disclosure controls and procedures. Based on that evaluation, the CEO and CFO have concluded that our disclosure controls and procedures are effective to ensure that the information required to be disclosed in
reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commissions rules and forms, and that such information is accumulated and
communicated to our management, including the CEO and CFO, as appropriate, to allow timely decisions regarding required disclosure.

Managements Annual Report on Internal Control over Financial Reporting

The management of Metals USA Holdings Corp. and its subsidiaries (the Company) is responsible for establishing and maintaining
adequate internal control over financial reporting. The Companys internal control system was designed to provide reasonable assurance to management and the Board of Directors regarding the reliability of financial reporting and the preparation
of financial statements for external purposes in accordance with generally accepted accounting principles.

All internal
control systems, no matter how well designed, have inherent limitations. Even those systems determined to be effective can provide only reasonable assurance with respect to financial statement presentation and preparation. Further, because of
changes in conditions, the effectiveness of internal control may vary over time.

Management conducted an evaluation of the
effectiveness of the Companys internal control over financial reporting based on the framework in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this
evaluation, management concluded that the Companys internal control over financial reporting was effective as of December 31, 2010.

Changes in Internal Control over Financial Reporting

We maintain a system
of internal accounting controls that are designed to provide reasonable assurance that our books and records accurately reflect the transactions of the Company and that our policies and procedures are followed. There have been no changes in our
internal controls during the fourth quarter that have materially affected, or are reasonably likely to materially affect such controls since the most recent evaluation of these controls as reported in our Form 10-Q for the period ended
September 30, 2010, including any corrective actions with regard to significant deficiencies or material weaknesses in our internal controls.
