Applications & Usage
This extra heavy-duty industrial Steel high-strength rectangular tube is commonly specified for heavy structural supports, load-bearing frames, and demanding industrial applications. The 10mm 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 | 879 kNm | 6408 kN | 12.5 mm · 147 kg/m (+23%) |
| S500MC | 500 MPa | 550–700 MPa | 1047 kNm | 7628 kN | 16 mm · 184 kg/m (+54%) |
| S600MC | 600 MPa | 650–820 MPa | 1256 kNm | 9154 kN | Beyond the S355J2H range of this size |
| S700MC | 700 MPa | 750–950 MPa | 1465 kNm | 10680 kN | Beyond the S355J2H range of this size |
In S500MC, this section (120 kg/m) carries the elastic bending load of a 16 mm S355J2H wall in the same outer size (184 kg/m), which is 54% 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.
