Nichols Aluminum Receives Environmental Award

HOUSTON, Feb. 6, 2008 (PRIME NEWSWIRE) -- Quanex Corporation (NYSE:NX), an industry-leading manufacturer of value-added engineered materials and components serving the Vehicular Products and Building Products markets, announced today that its Nichols Aluminum Davenport (NAD) plant was given a "Return on Environment Award" by General Electric Water & Process Technologies. The award is given to customers of the GE division that successfully demonstrate striking a balance between environmental challenges and industrial demands of a global economy.

"The NAD team, through collaborative efforts with GE, was able to save millions of gallons of water and $60,000 in wastewater treatment costs during the year," said Tom Brackmann, president of Nichols Aluminum. "Only about one percent of GE customers qualify for the award, which speaks volumes for the environmental advances our business has made."

Nichols Aluminum consists of two plants in Davenport, Iowa, one in Lincolnshire, Illinois, and one in Decatur, Alabama. Nichols Aluminum Casting (NAC), NAD's sister plant, handles the first part of the process of making aluminum sheet. NAC melts aluminum scrap and casts it into coiled aluminum sheet. These coils are then transported to NAD where they are rolled to thinner gauge, coated and cut into smaller coils used to manufacture products primarily for the building and construction markets.
