Seamless Aluminum Tube Solutions for All Your Industrial & Architectural Needs
Conglin’s Seamless Aluminum Tube Profiles
We provide seamless aluminum tube solutions that offer excellent pressure resistance for hydraulics and aerospace applications. Conglin’s profiles are free of welds or joints. Additionally, these tubes deliver superior strength, leak-proof performance, and fatigue resistance in high-pressure hydraulic cylinders, aircraft fuel lines, and pneumatic actuators.
We design them using premium 6061 and 6063 alloys; they provide tight tolerances and smooth interiors, available in diameters from 6mm to 250mm for mission-critical reliability.
Conglin Aluminum Technology brings over 30 years of expertise to the industry. We have been operating since 1992, producing high-end industrial aluminum profiles and alloy end-products. Our team of more than 1200 skilled staff works across various subsidiaries such as Longkou Conglin and Nollvetec. The company also manages two industrial zones equipped with 15 extrusion lines ranging from 1000T to 10,000T. This allows us to achieve an annual output of 100,000 tons. Our state-of-the-art facilities provide precise solutions for all your rail transit and automotive project needs.
