160×160×8 mm S235JRH Steel Square Hollow Section
160x160x8mm cold-formed ERW square hollow section to EN 10219, rolled in S235JRH, S275J0H or S355J2H depending on size, supplied with a primer-coated surface optimised for paint adhesion.
Minimum order
Minimum 10 t per size. If the size is already in the current production cycle, we can accept orders from 5 t. Standard length 6 m; 4–12 m on request. We confirm the minimum, lead time and grade in your quote.

Applications & Usage
Equal sides carry load about both axes, so this square hollow section is specified for columns, posts, gates, and frames, and the closed section resists torsion better than an open profile of similar weight. Supplied black, with a red-oxide shop primer, or hot-dip galvanized; the internal weld bead can be removed on request on most sizes.

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 | 51.1 kNm | 1091 kN |
| S275J0H | 275 MPa | 410–560 MPa | 59.9 kNm | 1277 kN |
| S355J2H | 355 MPa | 470–630 MPa | 77.3 kNm | 1649 kN |
Ordered in S355J2H, the S235JRH bending capacity of this size is reached with a 5 mm wall in the same outer size (23.8 kg/m, 35% lighter).
Indicative values from nominal dimensions: Wel × fy and A × fy, without buckling, cross-section class or partial safety factors. Not a design check.
