180 x 180 x 6.0 Square Hollow Section S235
The 180 x 180 x 6.0 Square Hollow Section S235 is a structural box section measuring 180 × 180 mm, equally strong about both principal axes and clean enough to leave exposed. The closed box is far stiffer in torsion than any open profile of similar weight, so an SHS post carrying an offset load twists very little.

At 33.3 kg per metre, one tonne buys roughly 30 linear metres. It is heavy enough to need mechanical handling on site, but light enough that a standard HIAB offload covers delivery in one visit. Stock grade is S235 to BS EN 10210 / BS EN 10219; other grades are rolled to order. Certification is EN 10204 3.1 as standard, and fabricated items are CE marked under BS EN 1090 EXC 3.
Typically specified for canopy and pergola structures, shop-front and glazing supports, architectural and exposed columns, mezzanine and platform posts and portal and goalpost frames.
Mitre cuts for frames are set out here from your overall frame dimensions rather than piece lengths.

answered.
Common questions about the 180 x 180 x 6.0 Square Hollow Section S235 — weight, grade, cut-to-length and worldwide delivery.
- It weighs 33.3 kg per linear metre, so a tonne is approximately 30 metres. A 6 m length comes to about 200 kg. Use the figure for lifting plant selection and for pricing, since structural steel is sold by weight.
