Applications & Usage
This heavy-duty structural Steel high-strength pipe is commonly specified for framework, support structures, machinery bases, and industrial equipment. The 6mm 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.

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.
| Grade | Min. yield ReH | Tensile Rm | Bending Wel·ReH | Axial A·ReH | S355J2H equivalent |
|---|---|---|---|---|---|
| S420MC | 420 MPa | 480–620 MPa | 87.5 kNm | 1687 kN | 8 mm · 41.6 kg/m (+32%) |
| S500MC | 500 MPa | 550–700 MPa | 104 kNm | 2008 kN | 10 mm · 51.6 kg/m (+64%) |
| S600MC | 600 MPa | 650–820 MPa | 125 kNm | 2410 kN | 12 mm · 61.3 kg/m (+94%) |
| S700MC | 700 MPa | 750–950 MPa | 146 kNm | 2812 kN | Beyond the S355J2H range of this size |
In S600MC, this section (31.5 kg/m) carries the elastic bending load of a 12 mm S355J2H wall in the same outer size (61.3 kg/m), which is 94% heavier per metre. In S700MC, 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.
