How is Colorbond Steel Made?

In 1976, BHP introduced a new coating of alloy that contains 55 % aluminum, 43% zinc, and 1.6% silicon, which is called ZINCALUME. Usually, the coating of steel is done by galvanizing (dipping the steel in molten zinc). 

Colorbond steel is the steel coated by baking the ZINCALUME coating onto the metal sheet. This product's trade name is COLORBOND. 

Colorbond steel is hence a treated zinc substrate. The steel base is treated with anti-corrosion and weather-resistant paint which makes colorbond fence material the best fit for the outdoor environment of Australian conditions.
