Applications & Usage

This lightweight and decorative Steel high-strength pipe is commonly specified for trim work, framing, display systems, and interior design projects. The 2mm 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.

High-strength grades for this size

Strength and indicative capacity for each grade this size is rolled in, compared with the S355J2H wall that carries the same bending load in the same outer size.

In S420MC, this section (0.952 kg/m) carries the elastic bending load of a 3 mm S355J2H wall in the same outer size (1.35 kg/m), which is 42% heavier per metre. In S600MC, this section carries more elastic bending load than any S355J2H wall rolled in the same outer size; matching it in S355 needs a larger section.

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