273 x 10.0 Circular Hollow Section S355
The 273 x 10.0 Circular Hollow Section S355 is a circular hollow section — a closed tube with no weak axis at all, which is why it is the go-to profile for exposed structural work. Because a circle has the same second moment of area about every axis, a CHS has no weak direction — the same section resists buckling identically whichever way the load leans.

At 64.9 kg per metre, one tonne buys roughly 15.4 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 exposed architectural columns, handrails and balustrade posts, gantry and sign posts, tubular trusses and bollards and street furniture.
Coped and profiled ends should be detailed on the drawing — the saddle cut is set out from the mating tube diameter.
