Zincalume steel coating combines the corrosion protection of aluminium with the sacrificial protection of zinc, giving the advantages of both metals. The resulting alloy coating enhances corrosion resistance, making it ideal for such applications as roofing and cladding.
Zincalume coated steel is produced by a continuous hot dip process similar to that used to manufacture galvanised steel. Zincalume coated steel has an alloy coating of 43.5% zinc, 55% aluminium and 1.5% silicon.
