Square Hollow Sections (SHS), Grade 350, various sizes (Specified by size & wall thickness)
Square Hollow Sections (SHS) Grade 350 are cold-formed structural steel products manufactured through electric resistance welding (ERW) of steel strip. The material offers superior structural efficiency with constant external dimensions across weight variations, making it ideal for standardised architectural and structural details. Compliant with AS/NZS 1163:2016, these sections provide 350 MPa minimum yield strength with excellent weldability and formability characteristics.

- Industrial equipment frames and supports
- Architectural features and exposed steelwork
- Temporary structures and scaffolding systems
- Mining and resource sector infrastructure
- Agricultural buildings and storage facilities
- Stadium and arena structures
- Transmission towers and communication masts
Square Hollow Sections emerged in Australian construction during the 1960s with the development of continuous electric resistance welding technology. The introduction of AS 1163 in 1981 standardised these products for the Australian market. Grade 350 became prevalent in the 1990s as design methods evolved to utilise higher strength steels efficiently. The 2009 revision of AS/NZS 1163 introduced impact property grades (L0), enhancing reliability for critical applications. Modern Australian production utilises automated manufacturing with inline quality control, producing consistent products meeting stringent standards. The material has become fundamental to Australian construction, particularly in multi-storey buildings, industrial facilities, and infrastructure projects across diverse climate zones from tropical Queensland to temperate Tasmania.
