Durable and UV Resistant 3K Carbon Fiber Square and Rectangular Tubes

Durable and UV Resistant 3K Carbon Fiber Square and Rectangular Tubes

3K Carbon Fiber Square and Rectangular Tubes are designed for applications requiring a combination of lightweight construction, high stiffness, durability, and excellent structural performance. Manufactured from high-quality 3K carbon fiber, these tubes provide an excellent strength-to-weight ratio while offering a clean, professional carbon fiber appearance.

The square and rectangular profiles provide flat surfaces and defined corners, making them particularly suitable for structural frames, supports, rails, and assemblies where round carbon fiber tubes may not be suitable.

Key Features

• High-quality 3K carbon fiber construction
• Lightweight with high strength and stiffness
• Excellent strength-to-weight ratio
• Durable outer surface
• Good UV resistance with suitable protective finishes
• Excellent corrosion resistance
• Good dimensional stability
• Square and rectangular cross-section options
• Glossy or matte surface finishes available
• Custom dimensions and wall thicknesses
• CNC cutting, drilling, and machining available
• UV Resistant and Durable Surface

For outdoor and demanding applications, UV resistance is an important consideration. A suitable surface coating or finish can help protect the carbon fiber tube from prolonged exposure to sunlight and environmental conditions while maintaining its appearance.

The durable surface is available in different finishes, including glossy and matte, allowing manufacturers to select the appearance that best matches their product design.

Square and Rectangular Profiles

Compared with traditional round tubes, square and rectangular carbon fiber tubes offer flat mounting surfaces and convenient alignment, making them suitable for structural assemblies.

They can be used to create lightweight frames and supports while maintaining excellent rigidity. Custom profile dimensions and wall thicknesses can be selected according to specific mechanical and installation requirements.

Durable and UV-resistant 3K Carbon Fiber Square and Rectangular Tubes offer an excellent combination of lightweight performance, high stiffness, durability, and design flexibility. With customized dimensions, surface finishes, and CNC machining options, they can be manufactured to meet the requirements of both standard and specialized applications.

Shanghai Lijin focuses on the Carbon Fiber industry and offers carbon fiber tubes, plates, and aluminum CNC services.

Being experienced in the carbon fiber applications for over 7 years, Shanghai Lijin manages customized production according to various industry standards. Shanghai Lijin started to keep in stock for some standard

sized and frequently ordered tubes and plates. This enables Shanghai Lijin to make prompt delivery. Not only

can Shanghai Lijin complete mass production orders in short period, we can even ship normal sample, prototype orders of Carbon Fiber Plate CNC parts in just SEVEN days after order confirmation when the

drawings are available. Shanghai Lijin is dedicated to solve any technical points during the production and new item developing to ensure the quality.

Carbon Fiber tube production is Shanghai Lijin’s core business and occupies 70% of our turnover.
The carbon fiber tubes Shanghai Lijin mainly produce is table-rolled and oven thermoset. The tubes can be Full Carbon or Carbon Fiber and Fiberglass composite, depending on the application, weight limit,mechanical

strength and surface requirement.Shanghai Lijin offers top quality ROUND carbon fiber tubes. The general OD tolerance we achieve is +/-0.10mm and it can be even +/-0.05mm after our special surface process.

The maximum length of the tube can be 5500mm.

Besides the traditional table-rolled carbon fiber tubes, Shanghai Lijin also offers REAL Filament wound carbon fiber tubes,which are widely used for mechanical strength like auto driving shaft, antennas, even for military

applications. The filament wound carbon tubes are wound at a certain angle like 30 or 45 degree. We invested the new production line from Jun 2013 and this increases Shanghai Lijin’s advantage in the carbon

fiber tube industry. There are just a few real filament wound carbon fiber tube manufacturers in domestic

China and we are one of them.
 

Since the rapid growth of UAV in the international market, instead of the standard plane like Phantom from DJI, RC fans are getting more interested in the customized multicopters. As carbon fiber is the most preferred

material for UAV, Carbon Fiber CNC parts demand is increasing. Shanghai Lijin sticks to offering OEM service for the international market, fine quality and prompt delivery.To ensure the thickness tolerance +/-0.10mm and minimum warp of the Carbon Fiber plates that are used for the cutting, Shanghai lijin execute high standard to

the plate production. For the normal thicknesses including 1.0mm, 1.2mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm,
Shanghai Lijin keeps regular stock, to make sure the raw material will be available for cutting immediately when order is firmed.Experienced engineers are in Shanghai Lijin’s office ready to deal with different types of

drawings from customers. No matter the drawing formats are .DWG, .DXF that can be edited by AutoCAD

and used directly for production, 3D drawings like .IGS, or even draft drawings, our staff can do adjustment and change to customer’s idea. Our engineers are also good at English communication, Email and IM is easy

for them. Editing drawings for customers is FREE* of charge. Shanghai Lijin is having several professional CNC machines for carbon fiber cutting and drilling, with the capacity of cutting 20-50pcs standard full sized plate per day. The carbon fiber chassis general cutting tolerance Shanghai Lijin offer is +/-0.02mm. The

special designed cutting solution ensures the smoothness of the cutting edge.

‘Customers’ Persuit for Change, Lijin’s Motivation for Growth’, Shanghai Lijin takes customers’ demand for center, enhances the
customer satisfaction, and grows with customer.
