Why COLORBOND® steel
Durability
With five layers of protection, COLORBOND® steel has been designed to endure our harsh Australian environment and provide long-lasting durability you can trust.

*Activate® technology is not available for COLORBOND® steel products with a galvanised steel substrate.
Thermal comfort
COLORBOND® steel’s core colour range in the Classic and Matt finish features our specially designed Thermatech® solar reflectance technology. Thermatech® reflects more of the sun’s heat on hot, sunny days which may help increase your comfort while reducing your dependence on air conditioning*. Thermatech® is available in all core colours except Night Sky®.
*Results will depend on roof colour, level and location of insulation, type and location of building shape and function.
