The ZINCALUME® coated steel has been formulated to give a significantly longer service life than a galvanised coating. This is of particular value in New Zealand where the prevailing winds carry corrosive salt laden air many kilometres inland.
The ZINCALUME® steel coating combines the corrosion protection of aluminium with the sacrificial protection of zinc to create an alloy that's ideal for roofing and cladding in New Zealand's demanding environment.
ZINCALUME® coated steel is produced by a continuous hot dip process similar to that used to manufacture galvanised steel. While both ZINCALUME® steel and galvanised steel products have a steel base, galvanised steel has a coating of 100% zinc, whereas ZINCALUME® coated steel has an alloy coating of 43.5% zinc, 55% aluminium and 1.5% silicon. ZINCALUME® coated steel conforms to AS1397:2011.
