Description
A 3m length of 30 x 30mm mild steel square box section with a 2.5mm wall, in EN 10219 S235JRH steel. Square hollow section for gates, railings, frames and general fabrication, supplied bare and ready to cut, drill, weld and paint. Each length weighs about 6.4 kg. The price shown is for one 3m length.
Why choose this box section
The everyday gate and frame size. 30mm box is a popular choice for pedestrian gate frames, railings and workbench frames, stiff without being heavy.
Stiff for its weight. A closed square section resists bending and twisting far better than flat bar or angle of the same weight, and gives clean, flat faces to weld and fix to.
EN 10219 S235JRH steel. The standard grade for welded structural hollow sections, easy to weld with MIG, TIG or stick.
A full 3m length. Long enough for gate and frame members with little waste.
Where it is used
Pedestrian gate frames, railings and balustrade posts, workbench and table frames, trailer frames, racking and general fabrication.

Cutting, welding and finishing
Cut with a metal cutting disc, band saw, chop saw or hacksaw, and deburr the cut. Mitre the corners at 45 degrees for neat gate and frame joints. Clean the faces where you weld, then weld with MIG, TIG or stick. Cap or seal open ends on outdoor work so water cannot collect inside. To finish, degrease, prime with a metal primer and top coat, or have the finished work hot-dip galvanised.
Frequently asked questions
Is the price for one length?
Yes, for one 3000mm length. For larger quantities, call us for a quantity price.
Is it painted or galvanised?
No. It is bare steel and will rust if left outside unprotected, so prime and paint it or galvanise it once your work is made.
What does S235JRH mean?
It is the steel grade for hollow sections: a minimum yield strength of 235 N/mm², impact tested at room temperature (JR), with H for hollow section, to EN 10219.
Can you cut it to length?
It is supplied in 3m lengths. Call us before you order if you need it cut, and we will tell you what we can do.
