Galvalume® Steel Sheet

Galvalume® steel sheet offers excellent corrosion protection in many applications through the combination of the sacrificial protection of conventional zinc coatings with the excellent barrier protection of aluminum. Steel Dynamics offers the widest Galvalume® sheet produced in North America, providing significant cost-savings opportunities for our customers. A variety of surface treatments are available to further inhibit oxidation or to improve formability. Our Galvalume® sheet is most commonly used in the manufacture of construction products where long-term corrosion performance is critical.
