ZINCALUME® - Metal Cladding NZ | ArchiPro


In New Zealand, where the prevailing winds carry corrosive salt-laden air many kilometres inland, ZINCALUME® offers the first line of defence. Zincalume® is an aluminium/zinc alloy coated steel that gives significantly longer service life than a galvanised coating for most roofing and cladding applications. The materials act in harmony with each other, combining the corrosion protection of aluminium with the sacrificial protection of zinc.

In the last 25 years, test sites from around the world have provided a wealth of information on the comparative performance of galvanised and Zincalume® coated steel products. Though corrosion rates vary according to the severity of conditions, Zincalume® steel coatings out-perform galvanised coatings in almost all environments. This is particularly true in marine environments where Zincalume® coated steel will provide a significantly longer service life than galvanised steel.
