250 x 250 x 8.0 Square Hollow Section S355
The 250 x 250 x 8.0 Square Hollow Section S355 is a square hollow section measuring 250 × 250 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 59.1 kg per metre, one tonne buys roughly 16.9 linear metres. This is a substantial member. Connection design, bearing detail and temporary stability all deserve attention at the drawing stage. Standard supply is S355 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.
