100 x 100 x 4.0 Square Hollow Section S235
The 100 x 100 x 4.0 Square Hollow Section S235 is a structural box section measuring 100 × 100 mm, equally strong about both principal axes and clean enough to leave exposed. Being square, the section behaves identically about both axes, which removes the orientation question entirely — useful for posts loaded from unpredictable directions.

At 12 kg per metre, one tonne buys roughly 83.3 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. 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.
Where an SHS post is set into a slab, specify the base detail — a welded plate is usually more reliable than a cast-in pocket.
