SQUARE / RECTANGULAR CARBON TUBE

Available Carbon Tube Sizes
IDs for standard square and rectangular carbon tube sizes are listed below. Wall thickness will depend on individual requirements. Standard walls range from 1.4 - 6.0mm; a price range (per metre) is shown for those thicknesses. Sizes not shown can be custom-ordered from C-Tech.

Both square carbon tube and rectangular carbon tube have radiused corners and flat sides approximately the same size as the tube ID. Corner radius will increase with wall thickness.

Prices are shown in NZ$, exclusive of GST.

Prices are appriximate per metre, based on a standard modulus laminate with approximately 30% hoop strength and manufacturing a tube to the full length of the tooling. Shorter lengths are available but may incur a higher per-metre price. 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).

Alternative laminate and fibre orientations can be custom-ordered from C-Tech.

Please note that there is a minimum order value of NZ $250 per shipment.
