Custom 3K Carbon Fiber Rectangular Tube 0.5mm - 20mm

Traditional 3K Rectangle Carbon Fibre Tube - Custom Sizes and Thickness

Our traditional rectangular composite tubes suit a variety of applications that need flat sides and make a great addition to any project. These stiff, lightweight tubes have incredible axial stiffness and can be cut to specific lengths with a wide range of tolerances. For custom sizes and thicknesses, tell us more about your requirements.

If you've got an idea for a rectangular carbon tube and know your specifications, choose your specs from the table below and send us a request for a quote. You can use the table to browse through internal diameters, outer diameters, wall thickness, price, and weight. Typical uses include Linear guides, measurement beams, spars and beams, UAV components, interior design, automation equipment, CNC cuttings, lase cutters, and sporting equipment.

About our products

• Wall thickness will depend on individual requirements.
• The outer corner radius will increase with wall thickness. inner radius defined by specific tooling or custom radius can be achieved if required.
• Standard walls range from 1.4 - 6.0mm; a price range per meter is shown for those thicknesses.
• Some over-run stock tubes can be ordered in smaller amounts and are available in specific sizes (quantities available vary constantly).
• Wall thicknesses of about 6.0mm or as thin as 0.5mm, or alternative laminate and carbon fibre orientations can be custom-ordered.

Benefits of rectangular carbon tubes

• High-tensile and torsional strength to low-weight ratio
• Resistance to fatigue
• Carbon RHS tubes weigh 60% of a size-for-size alloy tube
• Dimensional stability through temperature large ranges due to extremely low coefficient of thermal expansion (CTE), making RHS tubes popular for measurement tubes and for mounting linear guides
• Weigh as little as a third of the weight of aluminum tubes Can be used in either orientation to achieve different stiffness or mechanical properties in a single tube
• Square and RHS tubes can be machined with very flat faces or with holes for engineering purposes

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.
