139.7 x 10.0 Circular Hollow Section S355
Rolled and welded as a circular hollow section, the 139.7 x 10.0 Circular Hollow Section S355 combines structural efficiency with a clean visual line. 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 32 kg per metre, one tonne buys roughly 31.3 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. Held in S355 to BS EN 10210 / BS EN 10219 and cut to length before it leaves the yard. Mill certificates accompany every load, and any fabrication is executed under our BS EN 1090 EXC 3 factory production control.
Typically specified for tubular trusses, bollards and street furniture, canopy supports, bracing in exposed frames and roller and shaft sleeves.
Coped and profiled ends should be detailed on the drawing — the saddle cut is set out from the mating tube diameter.

answered.
Common questions about the 139.7 x 10.0 Circular Hollow Section S355 — weight, grade, cut-to-length and worldwide delivery.
- It weighs 32 kg per linear metre, so a tonne is approximately 31.3 metres. A 6 m length comes to about 192 kg. Use the figure for lifting plant selection and for pricing, since structural steel is sold by weight.
