Ultra-Strength Lightweight Carbon Fiber Round Tubes

Made of carbon fiber, these are the strongest composite round tubes we offer. Carbon fiber is comparable in strength to 6061 aluminum yet lighter in weight. These round tubes are often used to build frames and structures.

Tubes with a 0° construction layup have fibers that are aligned in a single direction for linear strength and rigidity. They resist bending but will crush easily if impacted. They’re often used to support structures.

Tubes with a 0°/90° construction layup have fibers that are aligned in two directions to resist crushing and twisting better than tubes with a 0° construction layup.

The appearance of checked tubes is the most common design for carbon fiber.

Glossy tubes reflect light and can be modified with a clear coat or sanded down for a matte finish.

Matte tubes don’t reflect light and can be painted without any prep work. They’re often used in photography applications.

Telescoping Ultra-Strength Lightweight Carbon Fiber Hexagonal Tubes

Color: Black
Temperature Range: -65° F to 180° F

Fiber Tensile Stiffness: Standard (33-36 msi)
Impact Strength: Not Rated
Hardness: Not Rated
For Use Outdoors: No

These tubes are stiff and have tensile strength comparable to aluminum—but are still lightweight—and can be placed inside one another to create an adjustable-length tube that resists twisting. Because they have flat sides, they’re easier to mount than round tubes. Use them to support moving equipment such as cameras and sensors. Built with a 0°/90° construction layup, they’re crush resistant and good for transferring torque. These tubes have a checked, glossy exterior, the standard for carbon fiber. They can be given a clear coat or sanded down for a matte finish. All tubes are roll wrapped.

For secure telescoping, choose a tube one size larger than the tube you’ll put inside it.
