Life Long Performance  

Bluescope Steel Colorbond® has a life expectancy of beyond 50 years.
Over a long period of research Bluescope Steel Colorbond® performance and weatherability, flexibility, adhesion, toughness, and appearance, has been raised to highest standards in severe testing of modern production techniques. In Australia alone, production of Bluescope Steel Colorbond® exceeds well in excess of 2.5 million tonnes per year. In extensive accelerated tests over 20 years, Bluescope Steel Colorbond® lasts up to four times longer than the traditional galvanised steel of the same thickness in identical exposure environments. Bluescope Steel Colorbond® is manufactured by BHP, the largest company in Australia.

The Manufacturer
Bluescope Steel Colorbond®


The Coated Products Division of the B.H.P. Steel International Group, is foundered on more than 70 years production in Australia and soon became the world's biggest producer per head of population of its products. B.H.P. began operations at Bristol England, in 1857. The Australian technology involved, has been
exported to the major steel makers of the U.S.A, Japan, and Europe, and are sold throughout South Asia, the Pacific, and the West Coast of USA. Australia's Bluescope Steel Colorbond® cladding products quickly won acceptance by Australian builders and architects.
More than 80% of all steel building cladding now used in Australia is manufactured from Bluescope Steel Colorbond®.
