Custom Size 3K Carbon Fiber Rectangular Tube Carbon Fibre Square Tube

 

LIJIN custom 3K carbon fiber rectangular and square tubes are manufactured from high-quality carbon fiber materials using advanced composite manufacturing processes. Featuring a distinctive 3K carbon fiber weave surface, these tubes combine an attractive appearance with excellent mechanical performance, making them an ideal solution for lightweight structural applications.

 

Our carbon fiber rectangular and square tubes offer an excellent strength-to-weight ratio, high stiffness, low weight, corrosion resistance, and dimensional stability. Compared with conventional metal profiles, carbon fiber tubes can significantly reduce structural weight while maintaining the rigidity and strength required for demanding applications.

 

LIJIN provides a wide range of custom sizes, wall thicknesses, fiber orientations, and surface finishes to meet different engineering requirements. Precision molds and strict production controls help ensure accurate dimensions, uniform wall thickness, excellent straightness, and consistent tolerances across production batches.

 

Our 3K carbon fiber square and rectangular tubes can be customized according to customer drawings, specifications, or application requirements. We support both prototype development and OEM mass production, providing professional services from material selection and mold development to tube manufacturing, cutting, drilling, and CNC machining.

 

These lightweight carbon fiber profiles are widely used in robotics, drones, UAVs, aerospace equipment, automation machinery, sporting equipment, industrial structures, telescopic systems, and other weight-sensitive applications.

 

Whether you require a standard carbon fiber square tube or a completely customized rectangular profile, LIJIN can provide high-quality carbon fiber solutions designed around your specific performance and dimensional requirements.

  • High Strength-to-Weight Ratio – Lightweight yet structurally strong.
  • High Stiffness – Excellent rigidity for structural applications.
  • Precision Dimensions – Controlled tolerances and uniform wall thickness.
  • Custom Sizes – Outer dimensions from 2 mm to 56 mm, with custom options available.
  • Multiple Fiber Orientations – Optimized layups for different mechanical requirements.
  • Excellent Corrosion Resistance – Suitable for demanding environments.
  • OEM & ODM Support – Custom manufacturing based on drawings and specifications.
  • CNC Machining Available – Additional cutting, drilling, milling, and other machining services can be provided.
