Step 1
Making Steel
BlueScope, headquartered in Australia, is one of the world’s leading producers of innovative steel materials.

Raw materials such as Iron Ore, Coking Coal and Flux are combined at incredibly high temperatures to produce steel materials for all purposes, including structural & reinforcing products, steel slabs, plates and rolled strip in various grades and gauges.

Step 2
Metallic Coating & Painting
Metallic coatings of zinc or aluminium/zinc/magnesium alloy are applied to cold-rolled strip to produce galvanised and ZINCALUME® steel, providing effective protection against corrosion. Different thicknesses of steel substrate and specialised coatings can be combined to provide even more protection for especially challenging environments.

The coated steel can be then prepainted on high-speed continuous strip coating lines to produce COLORBOND® steel in its famous range of finishes & colours, each tested to Australia’s unique conditions.

Step 3
Rollforming
LYSAGHT® uses these coils of lightweight coated steel to produce its wide range of building products, shaping them using a process called rollforming. By passing flat sheets of coated steel through a series of specially-designed rollers, the resulting steel products gain their required strength and rigidity.

Each arrangement of consecutive rollers produces a different result, producing iconic, industry-standard profiles such as CUSTOM ORB® corrugated roofing, KLIP-LOK® concealed-fix roofing, and BONDEK® composite steel formwork, all proudly made in Australia for more than 100 years.
