Clean COLORBOND® Ultra Thermatech®

Designed specifically for severe coastal & industrial environments found throughout Southern Africa, Clean COLORBOND® ULTRA steel gives you total peace of mind. It has a thicker coating of the zinc/alumimium coating of AZ200, which means that for every square metre of steel, there is a minimum of 200 grams of zinc/aluminium coating for even greater corrosion resistance. Metal sheeting, including exterior roofing and walling sheets, made from Clean COLORBOND® ULTRA steel will be able to better handle salt, pollution and other deposits that normally cause premature corrosion on metal sheets.

Clean COLORBOND® ULTRA steel has superior corrosion resistance, dirt resistance and paint performance properties making it one of the most cost effective building materials for harsh environments.

When YOU specify Clean COLORBOND® ULTRA steel, you not only benefit from BlueScope Steel’s steel making expertise, but it is also backed by a BlueScope Steel Warranty.

For further peace of mind, each product is individually branded on the bottom coat to ensure that you receive the genuine material.
