The Strength of Steel

Steel House Frames have In-built Durability. Corrosion Protection is Built In.

Protective coatings of zinc and aluminum alloy defend the steel against corrosion. New Zealand Steel Galvanized and ZINCALUME® coated steel coil, when used in framing components of above floor, steel frame cavity wall construction will meet a durability of 50 years.

The protective coatings on steel are tough, continuous, of uniform thickness, tightly adherent, and strongly resistant to corrosion. They are applied to both sides of the steel by the hot-dip process. In this process the steel strip is passed through a bath of molten metal, the amount of coating applied being closely controlled. The coating mass must meet the requirements of the relevant Australian Standard (AS 1397), or its equivalent.
