Applications & Usage
This heavy-duty structural Steel rectangular hollow section is commonly specified for framework, support structures, machinery bases, and industrial equipment. The 4.5mm wall thickness provides superior load-bearing capacity while maintaining workability. The applied finish enhances both durability and appearance. 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 | 5.93 kNm | 265 kN |
| S275J0H | 275 MPa | 410–560 MPa | 6.93 kNm | 310 kN |
| S355J2H | 355 MPa | 470–630 MPa | 8.95 kNm | 400 kN |
Ordered in S355J2H, the S235JRH bending capacity of this size is reached with a 3 mm wall in the same outer size (6.13 kg/m, 31% lighter).
Indicative values from nominal dimensions: Wel × fy and A × fy, without buckling, cross-section class or partial safety factors. Not a design check.
