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 | 225 MPa | 360–510 MPa | 1039 kNm | 7091 kN |
| S275J0H | 265 MPa | 410–560 MPa | 1224 kNm | 8351 kN |
Ordered in S355J2H, the S235JRH bending capacity of this size is reached with a 12 mm wall in the same outer size (170 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.
