Applications & Usage
This extra heavy-duty industrial Steel high-strength pipe is commonly specified for heavy structural supports, load-bearing frames, and demanding industrial applications. The 9mm 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.

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 | 159 kNm | 2797 kN | 12 mm · 68.8 kg/m (+32%) |
| S500MC | 500 MPa | 550–700 MPa | 189 kNm | 3329 kN | 14 mm · 79.6 kg/m (+52%) |
| S600MC | 600 MPa | 650–820 MPa | 227 kNm | 3995 kN | Beyond the S355J2H range of this size |
In S500MC, this section (52.3 kg/m) carries the elastic bending load of a 14 mm S355J2H wall in the same outer size (79.6 kg/m), which is 52% 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.
