What is Zinc-Aluminium -Alloy Coated Steel

The zinc -Aluminium material coating comprises:
  • Aluminum – 55%
  • Zinc – 43.4%
  • Silicon – 1.6%
Since Aluminium is known to possess excellent anti-corrosive properties, it provides a protective barrier against corrosion under normal weather conditions.
Atmospheric exposure tests have confirmed that the corrosion resistance feature of Zinc-Aluminium alloy coated steel is far superior to an ordinary zinc coating, since the 150 gms/ m2 coating (coating mass AZ 150) on an average, lasts up to four times that of galvanized steel which has a coating mass of 270 gms/ m2 (Z27) in similar environmental conditions.

Conformity to International Standards:

ZINC – ALUMINIUM alloy coated steel and Pre-painted steel conform to the following International Standard
  • ASTMB117
  • AS1397
  • ASTM A792
ZINC-ALUMINIUM steel is chosen as the substrate with PRE-PAINTED steel range for roofing and wall cladding applications. Pre-painted steel goes through a four stage process, whereby the ZINC-ALUMINIUM steel is applied with a conversion layer chemically applied. An epoxy primer is then baked onto the surface and thereafter a durable exterior grade top coat is baked on.
PRE-PAINTED steel is designed to give the superior strength of steel, the corrosion resistance of the ZINC-ALUMINIUM alloy coated steel and an oven-baked finish which is able to withstand varying weather conditions. The coating used in the manufacture of Pre-painted steel has been formulated to resist fading, peeling, chipping and cracking.
