Pultruded carbon fiber square tube(Hollow) manufactured from 100% unidirectional carbon fiber, which gives them excellent strength along their length but does make them vulnerable to crushing forces.

Pultruded tubes are ideal for scale aircraft, gliders, helicopter or any construction that requires strength, rigidity, and lightness. The Pultrusion process allows incredible tiny diameter tubes to be produced.

Pultrusion :

Pultrusion is a method of manufacturing continuous lengths of a fibre-reinforced section by pulling continuous strands of carbon fiber through resin and a former before curing the resin all in one process.
