Description
Galvanised round steel tube in five key clamp sizes, 26.9mm to 60.3mm outside diameter, in 1060mm, 1.5m and 3.5m lengths. Choose the diameter and length from the options above. Every size is the outside diameter that matching key clamp fittings are made for, galvanised for outdoor use and supplied with square cut ends, ready for handrails, guard rails, barriers and frames. The price shown is for one length of the size you choose.

Why choose this tube
Every common key clamp size in one place. 26.9, 33.7, 42.4, 48.3 and 60.3mm, so you can buy the rails, uprights and heavier posts for a job together.
Made for key clamp fittings. Each diameter takes the tees, elbows, flanges and crosses made for it, so a handrail or barrier goes together with an Allen key and no welding.
Galvanised for outdoors. The zinc finish protects the tube on ramps, steps, barriers and frames out in the weather.
Three useful lengths. 1060mm makes a ready-made upright with no cutting, 1.5m is easy to carry and suits short runs, and 3.5m gives long rails with fewer joins.
Which size do I need?
26.9mm is light and slim, for low rails, frames, shelving and garden structures. 33.7mm is a slim rail that sits well in the hand. 42.4mm is the most popular handrail size for steps and ramps. 48.3mm is the same diameter as scaffold tube and stiffer, for guard rails, barriers and longer spans. 60.3mm has a thick 3.6mm wall for barriers, tall posts and frames that take knocks or carry weight.

Cutting and fitting
