Square tubes, also known as carbon fiber box sections, are optimised for high-performance strength and stiffness. With in-built radiused corners and flat sides, they are ideal for building support systems, lightweight frames, and structures.

Square Carbon Fiber Tubes are manufactured using high-performance carbon fiber fabrics (commonly 3K weave) and epoxy resin, providing an excellent strength-to-weight ratio and rigidity. The square shape offers increased torsional resistance, easy mounting, and sleek aesthetics, making them perfect for drone frames, robotics, automation, camera rigs, and structural frameworks.

Carbon fiber tube is made of high-tech carbon fiber composite material, made of prepreg carbon fiber tube with high strength, stiffness, load bearing performance, and a lightweight (material density 1.9). Good corrosion resistance, good material stability. It can be used instead of metal, plastic, and other material members.

Key Feature

• Material: 100% Carbon Fiber (3K Twill or Plain weave)
• Shape: Square cross-section (equal side lengths)
• Finish: Glossy or matte
• Lightweight: Much lighter than aluminum or steel with similar strength
• High Stiffness: Excellent rigidity in both axial and torsional directions
• Corrosion-Resistant: No rust or degradation in outdoor or marine use
• Machinable: Can be cut, drilled, or CNC-machined

Applications

• UAV and drone frames (arms and booms)
• Robotic arms and structural supports
• 3D printer frames
• Industrial automation
• Lightweight support structures
• Telescopic or modular frames
