40 x 40 x 3.0 Square Hollow Section S235
The 40 x 40 x 3.0 Square Hollow Section S235 is a square hollow section measuring 40 × 40 mm — a closed box profile with four flat faces, giving tube performance with straightforward flat-to-flat connections. Being square, the section behaves identically about both axes, which removes the orientation question entirely — useful for posts loaded from unpredictable directions.

At 3.45 kg per metre, one tonne buys roughly 289.9 linear metres. It sits at the lighter end of the range, which keeps handling costs down and lets small teams position members without mechanical lifting plant. 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 architectural and exposed columns, mezzanine and platform posts, portal and goalpost frames, gate and railing frames and balustrade newel posts.
Where an SHS post is set into a slab, specify the base detail — a welded plate is usually more reliable than a cast-in pocket.
