Applications & Usage
This extra heavy-duty industrial Steel steel pipe is commonly specified for heavy structural supports, load-bearing frames, and demanding industrial applications. The 8mm 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.

Grade strength and capacity
Minimum strength of each grade this size is rolled in, with the indicative capacity of the section.
| Grade | Min. yield | Tensile | Bending Wel·fy | Axial A·fy |
|---|---|---|---|---|
| S235JRH | 235 MPa | 360–510 MPa | 230 kNm | 2353 kN |
| S275J0H | 275 MPa | 410–560 MPa | 269 kNm | 2754 kN |
| S355J2H | 355 MPa | 470–630 MPa | 347 kNm | 3555 kN |
Ordered in S355J2H, the S235JRH bending capacity of this size is reached with a 6 mm wall in the same outer size (59.2 kg/m, 25% lighter).
Indicative values from nominal dimensions: Wel × fy and A × fy, without buckling, cross-section class or partial safety factors. Not a design check.
