At Goodwinds, our pultruded carbon tubes are made from high-quality materials that are low cost and feature superior longitudinal stiffness. We can provide both standard and custom lengths with diameters as small as 0.125" and as large as 0.750" and a cut tolerance of 0.005". Our tubes are manufactured with carbon fibers that are unidirectionally oriented, resulting in enhanced mechanical characteristics. They feature a minimum tensile strength of 240 ksi, tensile modulus of 240 ksi, and shear strength of 6 ksi. Made from a bisphenol epoxy vinyl ester material matrix, each tube is designed and manufactured to serve a wide range of applications.

Since 2008, we've been supporting retail and wholesale customers with custom projects as well as bulk inventory programs. We have the capacity to handle virtually any production tempo, from prototyping to high volume runs. We field a knowledgeable team of composite engineers who can leverage years of experience in order to provide the best solution possible. As a one-stop shop, we work across all phases of manufacturing, supporting projects with secondary services such as custom precision cutting, chamfering, center-less grinding, drilling, sanding, and milling.

We carry an extensive line of tube sizes and profiles in-house, custom cut according to exact specifications. We are a Lean organization with a workforce that believes in organizational efficiency, continuously refining methods to ensure streamlined production. In addition, we're geared to handle both emergency and rush services.
