It’s not just white COLORBOND® steel, it’s an entirely tailored product. COLORBOND® Coolmax® steel is a roofing product designed to provide and maintain high solar reflectance, available in one very cool colour, Whitehaven®, with a Nominal Solar Reflectance1 = 0.77 and Solar Reflectance Index (SRI)1 = 95.
Designed to help reduce cooling costs, a nominal solar reflectance of 0.77 means it reflects 77% of the sun’s heat, which may help to reduce roofing temperatures and keep the building cooler2. Cooler, more energy efficient buildings make financial sense as well as environmental sense. Using COLORBOND® Coolmax® steel could help reduce the annual cooling energy costs of your building2. Particularly effective in large commercial buildings, COLORBOND® Coolmax® steel can help mitigate the impact of Urban Heat Islands (UHI).
All COLORBOND® steel products, including COLORBOND® Coolmax® steel are tested, tested and tested again. COLORBOND® Coolmax® steel has undergone real-world exposure testing and accelerated laboratory testing at BlueScope sites in Australia and conforms with relevant Australian Standards. Incorporating our Activate® technology for enhanced corrosion resistance, COLORBOND® Coolmax® steel is backed by BlueScope warranties3.

- Nominal values based on new product. Solar Reflectance is measured in accordance with ASTM E 903-96, standard test method for solar absorptance, reflectance and transmittance of materials using integrating spheres. SRI determined in accordance with ASTM E1980-11.
- Compared to conventional roofing materials of lower reflectance index (SRI), such as ZINCALUME® steel and all other roofing materials in the COLORBOND® steel range. Any savings and or the extent to which a building is cooler may vary and depend upon the particular circumstances of your building, including building location, level of insulation, location of air-conditioning when installed, building shape, building function and environmental factors. For further information download the Stockland case study.
- Warranty subject to exclusions, application, and eligibility criteria. For full terms and conditions and to determine the eligibility of your product for the warranty, please visit the BlueScope warranty website or contact us on 1800 800 789.
