180 x 180 x 8.0 Square Hollow Section S355
The 180 x 180 x 8.0 Square Hollow Section S355 is a square hollow section measuring 180 × 180 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 41.5 kg per metre, one tonne buys roughly 24.1 linear metres. Weight-wise it sits in the everyday working band — the size most frequently specified where span and access have to be balanced against each other. 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.
