Discover incredible strength, durability and innovation with our carbon fiber square tubes. The hollow structures with a square cross-section are made from carbon fiber-reinforced polymer (CFRP) composites. Due to their shape, square and rectangular, the tubes have a better areal moment of inertia which gives higher bending strength and structural integrity for demanding applications.

Precision Engineering
Available in 3K twill weave or plain weave patterns, with customizable glossy or matte finishes
Versatile Applications
Ideal for structural frameworks, robotic components, UAV systems, and specialized industrial solutions
NitPro Composites manufactures a wide variety of high-performance carbon fiber tubes. With specialized manufacturing processes of pultrusion and with prepreg materials. The tubes are available with Glossy and Matte finishes with unidirectional, plain and twill patterns in the following standard sizes and thicknesses (tolerance ± 0.2 mm).
Pultrusion is a highly efficient and cost-effective method of producing carbon fiber square tubes. This technique ensures consistent quality and is ideal for large-scale industrial applications requiring lightweight yet strong materials.
The pultrusion process involves continuously pulling carbon fiber composites through a resin matrix and heated forming dies. This results in long, unidirectional tubes with uniform cross-sectional properties.
Carbon fiber square tubes manufactured with prepreg layup method allow for precise engineering and superior aesthetics, making it ideal for high-performance applications requiring tailored solutions.
The prepreg process involves layering carbon fiber tubes impregnated with resin in specific orientations, followed by curing under controlled pressure and temperature. This results in tubes with dense reinforcement and outstanding performance.
