Carbon Tubes

Carbon Tubes


GW Composites pultruded  carbon tubes are an excellent choice if your application requires the greatest possible stiffness in the 0 degrees, or longitudinal direction. Pultruded carbon tubes offer the greatest possible stiffness longitudinally because the fibers are unidirectionally oriented. Another benefit to our pultruded carbon is the cost efficiency. Stock diameters run from .125” to .750” and we have a variety of stock lengths to choose from. Please contact us at 360-588-4785 or info@goodwinds.com if you need a custom length.
