Galvalume Sheet

Galvalume Steel Composition

Galvalume sheet is carbon steel sheet coated with aluminum-zinc alloy by a continuous hot dip process similar to the galvanizing process. The nominal coating composition is 55% aluminum and 45% zinc. Galvalume sheet combines the excellent barrier corrosion protection of aluminum with the galvanic protection of zinc. The result is a coating that lasts a long time, a coating that provides cut-edge protection along sheared edges, and therefore, a coating that offers excellent protection to steel sheet. It outlasts a galvanized coating of comparable thickness, and offers cut-edge protection that is not available with aluminum-coated sheet. Galvalume steel sheet is recommended when a high level of corrosion resistance is very important.
