Description
A square steel box section with a hammered edge pattern pressed along all four corners. 40 x 40mm with a 2.5mm wall, supplied as one 3m length in raw steel. It gives gate frames, posts and rails a hand-forged look without any forging. The price shown is for one 3m length.

Why choose this section
Forged look, standard tube. The hammered corners catch the light like hand-worked iron, but it cuts, drills and welds like ordinary box section.
Strong and light. A 2.5mm wall in EN10219 S235JRH steel is stiff enough for gate frames and posts while staying lighter than solid bar.
Easy to work. Cut it with a chop saw or grinder, then MIG, TIG or stick weld it. Cap the ends to keep water out.
Where it is used
Garden and driveway gate frames, railing posts and rails, balustrades, pergolas, garden furniture and decorative metalwork.

Yes, it is for one 3m length.
Can you cut it to size?
