AusSteel

Overview

AusSteel manufactures steel wall frames and roof trusses. Established in 1992, AusSteel has been an innovator in the steel frame and truss industry and has developed the AusSteel Ultimate Steel Building System through years of experience and refinement.

AusSteel’s system is a completely engineered and fully designed steel building solution created to meet the growing demand for steel framing in Australia. Using CAD-based design and engineering software, customised roll-forming techniques and a unique fastener system, every member and connection point is fully and reliably engineered.

AusSteel also manufactures floor systems, C-purlins and webbed floor joists, providing a solid foundation for a wide range of construction projects.

The AusSteel team has experience supplying projects ranging from small alterations and additions through to residential, multi-storey, commercial and industrial buildings.

AusSteel is an environmentally conscious company, using materials that are 100% recyclable, with all steel manufactured from 30% recycled steel.
