Square HollowGrade: S235

90 x 90 x 3.5 Square Hollow Section S235

The 90 x 90 x 3.5 Square Hollow Section S235 is a structural box section measuring 90 × 90 mm, equally strong about both principal axes and clean enough to leave exposed. The closed box is far stiffer in torsion than any open profile of similar weight, so an SHS post carrying an offset load twists very little.

At 9.72 kg per metre, one tonne buys roughly 102.9 linear metres. Light enough to be manoeuvred through existing openings, it is a common choice where a crane simply cannot reach the working face. Stock grade is S235 to BS EN 10210 / BS EN 10219; other grades are rolled to order. Certification is EN 10204 3.1 as standard, and fabricated items are CE marked under BS EN 1090 EXC 3.

Typically specified for portal and goalpost frames, gate and railing frames, balustrade newel posts, machinery frames and skids and canopy and pergola structures.

Mitre cuts for frames are set out here from your overall frame dimensions rather than piece lengths.
