What is Galvalume?

GALVALUME sheet steel coating is an alloy of 55% aluminum, 1.6% silicon, and the balance of zinc by weight, this coating is approximately 80% aluminum. The high aluminum content of the coating results in Galvalume sheet having a lower density and less weight per unit area than G90 galvanized sheet of equivalent thickness. This produces a product that is ideally suited for most types of roofing and siding applications.

The metallic coating is applied by a continuous “hot dip” process whereby properly cleaned low carbon, cold-rolled steel is dipped into molten aluminum-zinc bath. The patented alloy coating of Galvalume sheet provides an optimum balance between (a) the long term general corrosion resistance of Aluminum, and (b) the galgalvanic protection of zinc at scratches and cut edges.
