Quanex Building Products Corporation Announces Reload of Its Common Stock
Buyback Program

HOUSTON, Aug. 26, 2011 (GLOBE NEWSWIRE) -- Quanex Building Products Corporation
(NYSE:NX), a leading manufacturer of engineered materials, components and
systems serving domestic and international window and door OEMs through its
Engineered Products and Aluminum Sheet Products groups, today announced that on
August 25, 2011, its Board of Directors approved a reload to its existing common
stock buyback program.

Quanex's buyback program commenced on May 27, 2010, and it authorized the
company to purchase up to 1 million shares of common stock with the intent to
offset dilution and to take advantage of opportunistic circumstances. Through
August 24, 2011, Quanex has purchased 745,299 shares at an average price per
share of $15.41, including commissions. Assuming no meaningful change in its
stock price, the company estimated it would exhaust its authorized share balance
in the coming months. Therefore, the Board authorized a 1 million share reload
with the same goals -- offset dilution and take advantage of buying
opportunities as they present themselves.

"Because Quanex remains in a strong financial position, we are able to use our
cash in a combination of ways that best drive value for our long term
shareholders," said David Petratis, chairman and CEO of Quanex Building
Products. "This year, we made a great acquisition with the cash purchase of
Edgetech and we remain acquisitive, we continue to pay a respectable dividend,
and we've been opportunistically buying back common stock. Our long term view of
Quanex is extremely favorable, and when short term opportunities arise for us to
repurchase shares at attractive prices, it only makes sense to do so."
