Product Description

Traditional 3K Rectangle Carbon Fibre Tube - Custom Sizes and Thickness


Our traditional rectangular composite tubes suit a variety of applications that need flat sides and make a great addition to any project. These stiff, lightweight tubes have incredible axial stiffness and can be cut to specific lengths with a wide range of tolerances. For custom sizes and thicknesses, tell us more about your requirements.


If you've got an idea for a rectangular carbon tube and know your specifications, choose your specs from the table below and send us a request for a quote. You can use the table to browse through internal diameters, outer diameters, wall thickness, price, and weight. Typical uses include Linear guides, measurement beams, spars and beams, UAV components, interior design, automation equipment, CNC cuttings, lase cutters, and sporting equipment.


About our products

  • Wall thickness will depend on individual requirements.
  • The outer corner radius will increase with wall thickness. inner radius defined by specific tooling or custom radius can be achieved if required.
  • Standard walls range from 1.4 - 6.0mm; a price range per meter is shown for those thicknesses.
  • Some over-run stock tubes can be ordered in smaller amounts and are available in specific sizes (quantities available vary constantly).
  • Wall thicknesses of about 6.0mm or as thin as 0.5mm, or alternative laminate and carbon fibre orientations can be custom-ordered.

Benefits of rectangular carbon tubes

  • High-tensile and torsional strength to low-weight ratio
  • Resistance to fatigue
  • Carbon RHS tubes weigh 60% of a size-for-size alloy tube
  • Dimensional stability through temperature large ranges due to extremely low coefficient of thermal expansion (CTE), making RHS tubes popular for measurement tubes and for mounting linear guides
  • Weigh as little as a third of the weight of aluminum tubes Can be used in either orientation to achieve different stiffness or mechanical properties in a single tube
  • Square and RHS tubes can be machined with very flat faces or with holes for engineering purposes
