At Metal Source UK we offer a wide range of square and rectangular tubes on minimal production lead times. All tubes are available in lengths up to 10 meters and in a wide variety of surface finishes ranging from a standard mill finish to a superior marine quality mirror finish. We can also supply these with an ornamental plating in a variety of colours, including grey and black.
We have a broad scope of supply and can deliver worldwide in a timely manner.
These tubes are used in the following industries throughout the world:
