High-Quality Custom & High-Performance 3K Rectangular Carbon Fiber Tube

Our traditional rectangular composite tubes suit a variety of applications that need flat sides and make a great addition to any project. These stiff, lightweight tubes have incredible axial stiffness and can be cut to specific lengths with a wide range of tolerances. For custom sizes and thickness, tell us more about your requirements.

If you've got an idea for a rectangular carbon tube and know your specifications, choose your specs from the table below and send us a request for a quote. You can use the table to browse through internal diameters, outer diameters, wall thickness, price, and weight. Typical uses include: Linear guides, measurement beams, spars and beams, UAV components, interior design, automation equipment, CNC cuttings, laser cutter, and sporting equipment.

About our Products

Wall thickness will depend on individual requirements. The outer corner radius will increase with wall thickness. The inner radius defined by specific tooling or a custom radius can be achieved if required.

The carbon fiber tube is made by the tube rolling process, and can be designed with multi-angle ply to create high-performance, high-quality carbon fiber tubes. It can be widely used in medical equipment, sports equipment, drones, industrial machinery, and various rollers.

Benefits of Rectangular Carbon Tubes

• High-tensile and torsional strength to low-weight ratio.
• Fatigue resistance.
• Carbon RHS tubes weigh 60% of a size-for-size alloy tube.
• Dimensional stability through large temperature ranges due to extremely low coefficient of thermal expansion (CTE), making the RHS tube popular for measurement tubes and mounting linear guides.
• Weigh as little as a third of the weight of aluminum tubes. They can be used in either orientation to achieve different stiffness or mechanical properties in a single tube.
• Square and RHS tubes can be machined with very flat faces or with holes for engineering purposes.

Our carbon fiber rectangular tubing is widely applied to robot arms, helicopter models, drone models, and automobile parts. Our carbon fiber bent tubes with a high strength and light weight performance

It is critical to have a sound design, along with the right materials and process control. Our staff has extensive knowledge in customizing your rectangular carbon tubing and is here to assist in your project.

Most of our carbon fiber square tubes are made by Standard modulus carbon fiber (SM,) which is the most common grade of carbon fiber. Standard modulus offers excellent strength and stiffness. It is 7 times stiffer than aluminum and 5 times stiffer than steel; it is the most economical grade of material.
