Natural tube clamps are untreated and for that reason not suitable for outdoor use. They are somewhat darker gray in color and are often used in interior design.
The natural clamps are very suitable for powder coating in any color.
Clamps that are suitable for outdoor use are galvanised clamps or our special black clamps for outdoor use.
Our natural tube clamps are suitable for both indoor and outdoor use. The clamps have a matt grey finish.
Please note: as these clamps are untreated, they may already show slight signs of rust.
The natural tube clamps are ideal for powder coating.
When used outdoors, the surface will rust, creating a robust and industrial look similar to Corten steel.
If you wish to retain this effect without further rusting, the tube clamps can simply be treated with a clear varnish.
The untreated tube connectors are available in the following diameters: 26.9 mm, 33.7 mm and 42.4 mm.
