Why Choose Our Cylinder Aluminum Tube
Excellent Corrosion Resistance
With proper alloy selection and anodized treatment, our aluminum barrel tubes provide strong resistance to rust, moisture, and general industrial environments.
Precision Extrusion Quality
We focus on dimensional consistency, straightness, and inner surface quality, which are important for sealing performance and stable cylinder operation.
Lightweight but Strong
Compared with steel components, aluminum cylinder tubes offer a lower weight while maintaining good structural performance. This helps reduce overall equipment weight.
Custom Manufacturing Available
We can produce custom aluminum cylinder tubes according to drawings, dimensions, alloy grades, and surface requirements.
Quality & Manufacturing
- Strict inspection at every production stage to control dimensions, surface finish, and overall consistency
- Professional testing equipment supports reliable quality checks throughout the process
- Careful surface control to reduce pores, scratches, cracks, and other visible defects
- Controlled hard anodizing process with oxide layer thickness above 25μm and hardness up to HV420
About Conglin Aluminum
Founded in 1992, Conglin Aluminum is a leading manufacturer of industrial aluminum profiles and custom extrusions.
We offer standard and custom aluminum cylinder tube sizes for pneumatic cylinders, automation equipment, and industrial machinery. Both common dimensions and drawing-based specifications are available, with machining and surface treatment services supported.
Contact us today to discuss your Custom cylinder tube needs.
Aluminum Cylinder Tube Manufacturing Process
The aluminum material is processed through extrusion to form the required cylinder tube profile with stable cross-sectional dimensions.
After extrusion, the profiles are straightened and cut to the required length to ensure accuracy and good processing performance.
According to customer drawings, we can carry out CNC machining such as: Cutting to length, Drilling, Milling, Slotting, End processing
Common surface treatments include: Anodizing, Sandblasting, Polishing, and Custom surface finish
Anodizing is especially popular for anodized aluminum cylinder tubes because it improves corrosion resistance and surface durability.
Yes, we can provide aluminum cylinder tube samples for quality inspection. Standard stock samples are usually free to help reduce your sourcing cost, while custom sizes or special processing may require mold or sample charges.
If sample sizes are available in stock, sample preparation usually takes 7–10 days. For bulk orders, the lead time is normally 7–25 days, depending on the order quantity, specifications, and factory production schedule.
Our standard payment terms are 30% T/T in advance and 70% balance before shipment. For long-term customers, payment terms can be discussed further.
We can provide different surface finishes such as hard anodizing, polishing, and sandblasting. Normally, the outside surface is hard anodized, while the inside can be made with a matte sandblasted anodized finish, depending on the application requirements.
Yes, we can manufacture custom aluminum cylinder tubes according to your drawings or samples. Customization can include outer diameter, inner diameter, wall thickness, length, surface treatment, and CNC machining.
Yes. We carefully control the production process to reduce pores, scratches, cracks, and other visible defects. Through polishing and anodizing, we improve both surface smoothness and wear resistance.
