ZINCALUME® steel offers first-rate corrosion resistance and a lifespan of up to 4 times longer than ordinary galvanised steel. With its excellent forming capabilities and design versatility, ZINCALUME® steel is ideal for even the most innovative construction concepts. The surface of this material can be easily painted and the special resin coating protects the surface from unsightly marks.

​

COLORBOND™ steel offers an innovative pre-painted coating technology that is proven to keep your roof cooler and looking newer for longer. From city to farm, clean COLORBOND® TM comes in a variety of colours that will suit any environment and remain free from common stains for a clean and beautiful roof for years.

​

COLORBOND® ULTRA steel is designed specifically for external cladding application in severe coastal and industrial environments due to the higher coating class of its ZINCALUME® steel substrate, i.e. AZ200 (200g/m2 of Aluminium/Zinc alloy coating by triple spot test). The higher coating mass provides an additional degree of protection to the steel substrate. The fact that it features superior corrosion resistance in coastal and industrial environments while still being able to deliver excellent paint performance makes COLORBOND®

 

COLORBOND® ULTRA steel one of the most cost effective building materials to withstand exposure to the sea breeze, external industrial fall-out and other deposits that would cause accelerated corrosion. 

​

For harsher environments such as coastal and industrial areas, the coating class of AZ200 is strongly recommended. Based on our studies, AZ200 can last 60% longer than AZ150 in the same environment. We have COLORBOND® steel used next to the coastline and yet still able to provide long-lasting shelter.
