300 x 200 x 8.0 Rectangular Hollow Section S355
The 300 x 200 x 8.0 Rectangular Hollow Section S355 is a rectangular hollow section measuring 300 × 200 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. The closed profile means no lateral-torsional buckling check in the way an I-beam needs one, which often makes an RHS the simpler choice for an unrestrained span.

At 59.1 kg per metre, one tonne buys roughly 16.9 linear metres. Sections this heavy are usually part of a primary load path, so mill certification and dimensional tolerance matter as much as the section size itself. 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 balustrade top rails, trailer and plant chassis, sign and gantry structures, mezzanine edge beams and portal and goalpost frames.
For galvanised frames, vent holes are placed at the ends of each member to allow full drainage.

answered.
Common questions about the 300 x 200 x 8.0 Rectangular Hollow Section S355 — weight, grade, cut-to-length and worldwide delivery.
- It weighs 59.1 kg per linear metre, so a tonne is approximately 16.9 metres. A 6 m length comes to about 355 kg. Use the figure for lifting plant selection and for pricing, since structural steel is sold by weight.
