ZINCALUME® (by Bluescope Steel) is a zinc/aluminium alloy coated steel. It provides outstanding durability and is a significant improvement to the traditional zinc coated galvanised steel lasting some 4 times longer.
The ZINCALUME® steel coating combines the corrosion protection of aluminium with the protection of zinc, giving the advantages of both metals.
The resulting alloy coating enhances corrosion resistance.
ZINCALUME® coated steel has an alloy coating of 43.5% zinc, 55% aluminium and 1.5% silicon.
