Applications & Usage
This medium-duty Steel high-strength pipe is commonly specified for furniture manufacturing, enclosures, brackets, and general fabrication. The 3.5mm wall thickness provides excellent strength-to-weight ratio 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 | 1.26 kNm | 159 kN | Beyond the S355J2H range of this size |
| S500MC | 500 MPa | 550–700 MPa | 1.50 kNm | 190 kN | Beyond the S355J2H range of this size |
In S500MC, 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.
