Product Details<\/h2>\n

Pultrusion is the process you pick when you need carbon fiber tubes by the kilometer, not by the meter. Continuous fiber tows are pulled through a resin bath and into a heated die, where the profile cures in one pass \u2014 no mandrel wrapping, no vacuum bagging, no batch-by-batch curing. The result is a constant-cross-section tube with all fibers aligned along the 0\u00b0 axis, delivering the highest longitudinal tensile strength and stiffness per dollar of any carbon fiber tube process. If your application loads the tube primarily in tension or compression along its length \u2014 structural rails, push-pull rods, spar caps \u2014 pultrusion gives you more strength where you need it for less money.<\/p>\n

The trade-off is directional. Because virtually all the fiber runs lengthwise, a pultruded tube is weaker in transverse bending, crushing, and torsion than a roll-wrapped tube of the same dimensions. You can’t tune the ply angles or add hoop reinforcement \u2014 the die geometry and pull speed are fixed. If your design needs \u00b145\u00b0 shear plies, 90\u00b0 hoop wraps, or a cosmetic 3K twill outer layer, see our roll wrapped carbon fiber tubes<\/a><\/strong>. But for straight, long, axially loaded members where cost-per-meter matters, pultrusion is the right process.<\/p>\n

Our Shenzhen pultrusion line produces single-piece tubes up to 4 meters long \u2014 one of the longest capabilities among Chinese carbon fiber tube manufacturers. Available cross-sections include round (3mm\u2013200mm OD), square, and rectangular profiles. Wall thickness from 0.5mm to 10mm. The continuous process means every meter of a 50-meter run is dimensionally identical \u2014 same OD, same wall, same fiber content. For OEM customers ordering thousands of meters per month, that consistency is worth more than any single-tube strength spec.<\/p>\n
