Applications & Usage

This heavy-duty structural Steel high-strength pipe 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.

In S600MC, this section (12.2 kg/m) carries the elastic bending load of a 10 mm S355J2H wall in the same outer size (25.7 kg/m), which is 111% heavier per metre.

Indicative values from nominal dimensions: Wel × ReH and A × ReH, without buckling, cross-section class or partial safety factors. Not a design check.
