Re:		Quanex Corporation Preliminary Proxy Statement on Schedule 14A Filed on: December 20, 2007 File No. 001-05725

Ladies and Gentlemen:

     By letter dated January 2, 2008, Quanex Corporation (the “Company”) received the Staff’s comments relating to the above listed filing of the Company (the “Comment Letter”). On behalf of the Company and in response to the Comment Letter, we submit the following responses. The following numbered paragraphs repeat the comments in the Comment Letter for your convenience, followed by the Company’s responses to those comments.

The Spin-Off, page 3

     1. We note from your filing that your stockholders’ approval is not needed in connection with the proposed spin-off of the Building Products Group to Quanex’s stockholders. However, since the spin-off is a condition to the completion of the merger, we direct your attention to Note A of Schedule 14A which requires you to provide your stockholders with information related to the spin-off and Quanex Building Products Corporation (and other related affiliates) in accordance with Items 11, 13 and 14 of Schedule 14A of Regulation 14A. Please amend your filing to include financial and other information related to the spin-off.

     Response: Quanex Building Products Corporation (“QBPC”) has, concurrently with the filing of this comment response letter, filed a Form 10 to register the shares of its common stock that the Company’s stockholders will receive in the spin-off. The Company intends to incorporate QBPC’s Form 10 by reference into the proxy statement to include the information required by Items 11, 13 and 14 of Schedule 14A of Regulation 14A with regard to financial and other information related to the spin-off.

     2. We further note that your preliminary proxy statement is missing a discussion in connection with any required filings related to the spin-off. We refer to Division of Corporation

Finance Staff Legal Bulletin No. 4 dated September 16, 1997, which addresses the conditions pursuant to which the subsidiary will not register the spin-off under the Securities Act. One of the conditions requires that the parent provide adequate information about the spin-off and the subsidiary to its shareholders and to the trading markets. Since Building Products Corporation and Building Products LLC are non-reporting subsidiaries, the appropriate subsidiary must register the spun-off shares under the Exchange Act. Please explain how you intend to comply with the registration requirements identified in the staff bulletin. Please inform us if you are in the process of preparing a Form 10 filing.

     Response: As stated in the response to comment 1 above, QBPC has, concurrently with the filing of this comment response letter, filed a Form 10 to register the shares of its common stock that the Company’s stockholders will receive in the spin-off. The Form 10 is intended to comply with the registration requirements identified in Division of Corporation Finance Staff Legal Bulletin No. 4 dated September 16, 1997.
