COLORBOND® Steel has Zincalume® steel, a Zinc-Aluminium 55% Alloy Coated Steel, as a core substrate. It provides both barrier protection from Aluminium and galvanic protection from Zinc. On an average Zincalume® steel lasts up to 4 times longer than Galvanised steel in similar environmental conditions.

A combination of airborne particles, heat and humidity sticks on the surface of a metal sheet will eventually lead to dark stains on it. Over time, the building will look dirty and aged. Clean Technology in COLORBOND® Steel proprietary paint system prevents this bonding process, making the dirt particles always remain loose and washable by rainfall for a brand-new look.

Thermatech® technology in our paint system optimizes the solar reflectance properties of COLORBOND® Steel. As a result, your building surface reflects more sun’s rays and absorbs less heat for cooler surface temperature. Even the darker shades have better thermal efficiency without any changes in their appearance.

To help create a more sustainable ‘circular economy’, every COLORBOND® Steel product incorporates recycled material and the steel itself is 100% recyclable. Moreover, COLORBOND® Steel‘s proven longevity keeps resources in use for longer, minimizing its impact on the environment.

For your best peace of mind, BlueScope offers you the maximum warranty for COLORBOND® Steel with 30-year against perforation due to corrosion, 10-year against color fading and chalking and 5-year for dirt stain retention property.
