Applications & Usage
This medium-duty Steel rectangular hollow section is commonly specified for furniture manufacturing, enclosures, brackets, and general fabrication. The 3mm wall thickness provides excellent strength-to-weight ratio while maintaining workability. The natural mill finish provides a cost-effective solution for applications where aesthetics are secondary. Available in standard lengths of 6m, this profile can be easily cut, drilled, and welded to suit your specific requirements.
