Square Carbon Fibre Tubes
Square tubes, also known as carbon fiber box sections, are optimised for high-performance strength and stiffness. With in-built radiused corners and flat sides, they are ideal for building support systems, lightweight frames and structures.
Available carbon fiber box section sizes
If you've got an idea for square carbon tubing and know your specifications, choose your specs from the table below and

Wall thickness will depend on individual requirements.
Corner radius will increase with wall thickness.
Standard walls range from 1.4 - 6.0mm; a price range (per metre) is shown for those thicknesses
As all tubes are made to order, the minimum order length is [usually] 1.0m
Some over-run tube, which can be ordered in shorter lengths, is available in specific sizes (quantities available vary constantly).
Wall thicknesses above 6.0mm or alternative laminate and carbon fiber orientations can be custom-ordered.
