Applications & Usage
This extra heavy-duty industrial Steel rectangular hollow section is commonly specified for heavy structural supports, load-bearing frames, and demanding industrial applications. The 6.3mm wall thickness provides exceptional structural integrity 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.
