Applications & Usage
This lightweight and decorative Steel rectangular hss is commonly specified for trim work, framing, display systems, and interior design projects. The 1.98mm wall thickness provides adequate strength for light-duty applications 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.
