Frequently asked questions

What lengths does the tube come in?

Three lengths - 1m, 2m and 3m - so you can pick the size closest to your build and cut down from there.

Can I cut it to a custom length?

Yes. It cuts cleanly with a hacksaw, an angle grinder or the dedicated cutting jig for square tubes.

What joints and connectors fit this tube?

It is a 25mm x 25mm section, so it works with the full range of square tube joints and connectors, from straight couplers to multi-way corner joints.

Is the wall thickness the same across all lengths?

No - the 1m and 2m lengths are 1mm wall thickness, while the 3m length is 2mm for extra rigidity over the longer run.

Can I use it outdoors?

Yes. The black epoxy coating is suited to indoor and outdoor use and resists corrosion.

Do I need welding equipment to build with it?

No - the tube connects to the joint and connector range without welding, so it can be assembled with simple hand tools.

What is the tube made from?

Steel with a black epoxy coating for a durable, corrosion-resistant finish.
