Applications & Usage
This heavy-duty structural Steel rectangular hollow section is commonly specified for framework, support structures, machinery bases, and industrial equipment. The 4.5mm wall thickness provides superior load-bearing capacity 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.
