Description
A 3m length of galvanised 25 x 25mm square box section with a 2.5mm wall, ready for outdoor frames, rails and gates. The zinc coating is already on, so a simple frame can be cut, bolted or clamped together with no painting. Each length weighs about 5.4kg. The price shown is for one 3000mm length, with a minimum order of 3 lengths.
Why choose this box section
Already galvanised. You skip the primer and top coat that bare steel box needs outdoors. That is a real saving on a frame that is going to live in the weather, and it is the reason to choose this over black steel.
A useful light frame size. 25mm box with a 2.5mm wall is a good size for small gates, guards, racking and frames. It stays easy to carry and cut, and a 2.5mm wall gives fixings something to bite into.
Stiff for its weight. A closed square section resists bending and twisting better than flat bar or angle of a similar weight, and its four flat faces are easy to fix to.
Works with 25mm square fittings. The 25mm outside size suits square key clamp fittings made for 25 x 25mm box, so a frame can go together with an Allen key rather than a welder.
Where it is used
Outdoor frames and guards, small gates and gate infills, garden and allotment structures, shelving and stillage frames, sign frames, machine guards and general light fabrication.

Cutting, fixing and finishing
Cut with a metal cutting disc, band saw, chop saw or hacksaw, then deburr the cut. Any cut or drilled edge exposes bare steel, so touch it up with a zinc rich paint to keep the protection going. Cap open ends on outdoor work so that water cannot collect inside.
If you need to weld it, grind the zinc back from the weld area first and work with good extraction, because fumes from burning zinc are harmful. Treat the weld with zinc rich paint afterwards.
Frequently asked questions
Is the price for one length?
Yes, for one 3000mm length. The minimum order is 3 lengths. For larger quantities, call us for a quantity price.
Can it be painted?
Yes, but new galvanising needs preparing first. Degrease it and use a primer made for galvanised steel, or the paint may not hold.
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.
What does the 25mm refer to?
It is the outside size of the square. With a 2.5mm wall, the hollow inside measures about 20 x 20mm.
Will it fit a 25mm round key clamp?
No. Round tube fittings are made for round tube. Use fittings made for 25 x 25mm square box section.
