Applications & Usage
This heavy-duty structural Steel square hss is commonly specified for framework, support structures, machinery bases, and industrial equipment. The 4.76mm wall thickness provides superior load-bearing capacity 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 calculated on the AISC design wall (0.93 × nominal).
| Grade | Min. yield | Tensile | Bending Wel·fy | Axial A·fy |
|---|---|---|---|---|
| Grade B | 46 ksi (315 MPa) | 58 ksi (400 MPa) | 16.0 kNm · 11.8 kip·ft | 526 kN · 118 kips |
| Grade C | 50 ksi (345 MPa) | 62 ksi (425 MPa) | 17.6 kNm · 13.0 kip·ft | 576 kN · 130 kips |
Indicative values from nominal dimensions: Wel × fy and A × fy, without buckling, cross-section class or partial safety factors. Not a design check.
