150 x 150.x12.0 Square Hollow Section S355
Formed as a square hollow section measuring 150 × 150 mm, the 150 x 150.x12.0 Square Hollow Section S355 is the usual choice for posts that also have to look finished. 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 47.1 kg per metre, one tonne buys roughly 21.2 linear metres. Sections this heavy are usually part of a primary load path, so mill certification and dimensional tolerance matter as much as the section size itself. Held in S355 to BS EN 10210 / BS EN 10219 and cut to length before it leaves the yard. Mill certificates accompany every load, and any fabrication is executed under our BS EN 1090 EXC 3 factory production control.
Typically specified for gate and railing frames, balustrade newel posts, machinery frames and skids, canopy and pergola structures and shop-front and glazing supports.
Mitre cuts for frames are set out here from your overall frame dimensions rather than piece lengths.
