21.3 x 3.0 Circular Hollow Section S235
21.3 x 3.0 Circular Hollow Section S235 is a CHS, a seamless-looking tubular member equally stiff in every direction. Closed profiles are enormously stiffer in torsion than any open section, so a CHS is the sensible answer for cantilevered signage, gantry arms and anything that twists.

At 1.43 kg per metre, one tonne buys roughly 699.3 linear metres. Light enough to be manoeuvred through existing openings, it is a common choice where a crane simply cannot reach the working face. Supplied in grade S235 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 handrails and balustrade posts, gantry and sign posts, tubular trusses, bollards and street furniture and canopy supports.
Galvanising a closed section needs vent and drain holes; we position them where they will not be seen.
