BlueScope products give builders and certifiers a number of assurances:

  • Fully traceable to the point of production.
  • Conform to all relevant standards - including AS 1397:2021, which relates to the metallic coating and substrate, and AS/NZS 2728:2013, covering the performance requirements for pre-painted sheet metal.
  • Clearly branded and can be easily identified.
  • Full documentation - including test certificates, data sheets and project warranty - are available.

In addition BlueScope is at the forefront of steel coating innovation:

Thermatech® Solar Reflectance Technology 

21 out of the 22 standard colours (except Night Sky®) in the COLORBOND® steel roofing and walling range feature Thermatech® solar reflectance technology1. Thermatech® technology is designed to reflect more of the sun's heat on hot, sunny days, which can help reduce dependence on air-conditioning2.

COLORBOND® Coolmax® steel

COLORBOND® Coolmax® steel is a roofing product specifically designed to provide and maintain high solar reflectance.

With a nominal solar reflectance of 0.77, it may help to reduce roofing temperatures and keep buildings cooler3.

Activate® Metallic Coating Technology

Activate® technology is BlueScope's industry leading, patented, metallic coating for enhanced corrosion resistance. ZINCALUME® steel and TRUECORE® steel feature Activate® technology, as does COLORBOND® steel (except for COLORBOND® steel products on a galvanised steel substrate).

Not all steel products are created equal, and the BlueScope brand is a proven way to ensure high quality and industry-compliant products.

Risks of non-compliance & how to specify for:

  • Roofing & Walling
  • Cold Formed
  • Welded Beams

How to ensure compliance:

  • Identifying Markings



1 Thermatech® technology is not available in Night Sky®, or non-standard colours, and is not available in COLORBOND® Metallic steel, COLORBOND® Coolmax® steel or COLORBOND® Intramax® steel.

2 Results will depend on roof colour, level and location of insulation, type and location of building shape and function.

3 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.
