120 x 120 x 5.0 Square Hollow Section S235
The 120 x 120 x 5.0 Square Hollow Section S235 is a square hollow section measuring 120 × 120 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 18 kg per metre, one tonne buys roughly 55.6 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 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.
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.
