120 x 120 x 6.0 Square Hollow Section S235
The 120 x 120 x 6.0 Square Hollow Section S235 is a structural box section measuring 120 × 120 mm, equally strong about both principal axes and clean enough to leave exposed. Flat faces make connections much simpler than on circular tube: plates, cleats and brackets weld or bolt straight on without profiling.

At 18 kg per metre, one tonne buys roughly 55.6 linear metres. This is a mid-weight member: comfortable for a telehandler or small mobile crane, and heavy enough to carry meaningful load without doubling up. 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.
Closed sections need vent holes before hot-dip galvanising; tell us if the position is visually sensitive.
