300 x 300.x10.0 Square Hollow Section S355
300 x 300.x10.0 Square Hollow Section S355 is an SHS measuring 300 × 300 mm, combining the torsional stiffness of a closed section with faces you can actually bolt a plate to. Being square, the section behaves identically about both axes, which removes the orientation question entirely — useful for posts loaded from unpredictable directions.

At 88.4 kg per metre, one tonne buys roughly 11.3 linear metres. This is a substantial member. Connection design, bearing detail and temporary stability all deserve attention at the drawing stage. Supplied in grade S355 to BS EN 10210 / BS EN 10219, cut to your lengths and delivered worldwide. Heat numbers are traceable back to the rolling mill, with EN 10204 3.1 certificates issued against each delivery.
Typically specified for mezzanine and platform posts, portal and goalpost frames, gate and railing frames, balustrade newel posts and machinery frames and skids.
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.
