What is Clean COLORBOND® steel – SPECTRUM SERIES?

ZINCALUME® Steel
Clean COLORBOND® steel SPECTRUM SERIES is prepainted ZINCALUME® steel as the substrate. The metallic coating on ZINCALUME® steel comprises of 43.5% zinc, 55.0% aluminium and 1.5% silicon, which can provide a superior resistance against corrosion. It is available in two grades: G300 and G550 (minimum yield strength of 300 MPa or 550 MPa).

Durable Paint System
For better paint durability, BlueScope Steel applies an oven cured polyester paint, whereby the system is made of inorganic pigments. To further enhance the surface performance, we provide a corrosive inhibitive primer & backing coat.

Clean Technology
In order to prevent dirt staining, the Clean technology which resists the bonding of dirt is applied on top of the coating. The “loose” surface dirt can be easily washed off during normal rainfall, restoring the original colour of the prepainted steel surface.

Warranty

• 25 years against corrosion*
• 10 years against paint fading, peeling and chalking*
