Why BlueScope steel is the standard for Australian sheds

If you’ve looked at any shed quote in Australia, you’ve probably seen “BlueScope Steel” mentioned. It’s not just a brand name; it’s the backbone of the Australian shed industry.

What is BlueScope Steel?

BlueScope is an Australian steel manufacturer based in Port Kembla, NSW. They produce the steel used in the vast majority of residential and commercial sheds across Australia, including well-known product lines like:

• Colorbond: pre-painted steel for roofing and walling
• Zincalume: zinc/aluminium coated steel for corrosion resistance
• Galvaspan: steel for structural framing and purlins

Why does it matter?

Engineered for Australian conditions

BlueScope steel is specifically designed and tested for Australian weather, from tropical cyclones in the north to coastal salt spray and alpine snow loads. Imported steel isn’t always rated for these conditions.

Warranty backed

Colorbond roofing on homes comes with warranties of up to 36 years, and shed and garage applications carry warranties of up to 15 years, depending on the environment. That’s a level of confidence you won’t get with unbranded or imported steel.

Consistent quality

Because BlueScope controls the manufacturing process end-to-end in Australia, the steel you get is consistently graded, coated, and finished. This makes it easier for engineers to certify and for builders to work with.

Colour range

Colorbond offers over 20 colours designed to suit the Australian landscape, from Surfmist and Shale Grey to Monument and Woodland Grey. You can preview many of these in our 3D design tool.

What Shed Designer requires
