High-Strength Lightweight Carbon Fiber Round Tubes

Often used in place of aluminum for structural frames, machinery components, and robotics, these tubes are lighter in weight and almost as rigid. Carbon fiber is known for its use in the aerospace industry where a balance of weight and strength is vital. Thanks to these tubes being lightweight, they reduce wear and stress on motorized parts to extend the life of machinery.

Plain Glossy Round Tubes

Image of Product. Front orientation. Carbon Fiber. High-Strength Lightweight Carbon Fiber Round Tubes, Glossy, Plain.

Plain glossy tubes have layers with fibers that alternate in two directions, so they resist bending and crushing across the entire tube. They have more structural integrity compared to plain matte tubes.

Glossy carbon fiber can be sanded for a matte finish or to prep it for painting.

Plain Matte Round Tubes

Image of Product. Front orientation. Carbon Fiber. High-Strength Lightweight Carbon Fiber Round Tubes, Matte, Plain.

Plain matte tubes have fibers that run in one direction, making them strong in the direction of the fibers. They resist bending across the fibers but will splinter and separate like string cheese when bent along the length of the fiber.

Matte carbon fiber is ready to paint and won’t reflect light, making it ideal for photography applications.

Checked Glossy Round Tubes

Image of Product. Front orientation. Carbon Fiber. High-Strength Lightweight Carbon Fiber Round Tubes, Glossy, Checked.

Checked carbon fiber is easy to machine and will not fray or splinter when cut. It has the classic carbon-fiber look. Checked tubes have layers with fibers that alternate in two directions, so they resist bending and crushing across the entire tube. They have more structural integrity compared to plain matte tubes.

Glossy carbon fiber can be sanded for a matte finish or to prep it for painting.

High-Strength Lightweight Carbon Fiber Rods

Reinforce structures with these rods—they weigh less than aluminum while remaining strong and almost as rigid. Their fibers are aligned in a single direction, so they hold up to bending across the fibers but will splinter and separate like string cheese when bent along the length of the fiber. Carbon fiber is known for its use in the aerospace industry where a balance of weight and strength is vital.

Rigid High-Strength Lightweight Carbon Fiber Round Tubes

Often used for structural framing, machinery components, and robotics, these carbon fiber tubes are as stiff as steel yet a fraction of the weight. Carbon fiber is known for its use in the aerospace industry where a balance of weight and strength is vital. Because they are lightweight, they reduce wear and stress on motorized parts, which increases the life of machinery. These tubes are constructed with layers that alternate fibers in two directions, making them difficult to bend.

The checked pattern on these tubes keeps fibers from splintering when the tubes are cut, making them easy to machine. It also has a classic carbon-fiber look. These tubes are glossy and can be sanded for a matte finish.

Telescoping High-Strength Lightweight Carbon Fiber Hex Tubes

Fit these lightweight tubes inside each other to create adjustable tubes for structural framing, machinery components, and robotics. Their hex shape prevents these tubes from twisting when they’re inside larger tubes and allows you to mount them to flat surfaces. Carbon fiber is often used in place of aluminum because it weighs less but is almost as rigid. It is known for its use in the aerospace industry where a balance of weight and strength is critical. These tubes reduce wear and stress on motorized parts and increase the life of machinery since they're lightweight.

These tubes have layers that alternate fibers in two directions, so they resist crushing across the tube. This checked carbon fiber is easy to machine—it won’t fray or splinter when cut. It also has the classic carbon-fiber look. The surface is glossy and can be sanded for a matte finish.
