80 x 40 x 4.0 Rectangular Hollow Section S235
The 80 x 40 x 4.0 Rectangular Hollow Section S235 is a rectangular hollow section measuring 80 × 40 mm — a closed box that is deliberately deeper than it is wide, so it spans like a beam but still resists twist like a tube. Depth is put where bending demand is, so an RHS spans considerably better than a square section of the same weight while still refusing to twist.

At 6.97 kg per metre, one tonne buys roughly 143.5 linear metres. It sits at the lighter end of the range, which keeps handling costs down and lets small teams position members without mechanical lifting plant. Standard supply is S235 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 portal and goalpost frames, agricultural building framing, canopy and carport beams, exposed architectural framing and balustrade top rails.
Where RHS members meet at a corner, mitred and welded joints are usually cleaner than a bolted cleat; send the frame geometry and we will set it out.
