70 x 70 x 3.0 Square Hollow Section S235
The 70 x 70 x 3.0 Square Hollow Section S235 is a square hollow section measuring 70 × 70 mm — a closed box profile with four flat faces, giving tube performance with straightforward flat-to-flat connections. 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 7.4 kg per metre, one tonne buys roughly 135.1 linear metres. Light enough to be manoeuvred through existing openings, it is a common choice where a crane simply cannot reach the working face. Standard supply is S235 to BS EN 10210 / BS EN 10219, with fabrication carried out here before dispatch. Every order carries EN 10204 3.1 mill certification and is CE marked under BS EN 1090 EXC 3.
Typically specified for balustrade newel posts, machinery frames and skids, canopy and pergola structures, shop-front and glazing supports and architectural and exposed columns.
Mitre cuts for frames are set out here from your overall frame dimensions rather than piece lengths.
