Conglin Aluminum Large Cross-Section Aluminum Alloy Profiles for High-Speed Rail & Industrial Applications

Advanced Production Technology & Equipment

Our large cross-section aluminum alloy profiles at Conglin Aluminum are built specifically for high-speed rail carriages and heavy-duty industrial structural projects. We possess a large-scale extruder that handles one-time forming of complex, large cross-section profiles, which helps us keep quality consistent across every batch and guarantee outstanding structural strength for critical end-use applications.

Authoritative Certifications & Global Partnerships

We’re the exclusive Chinese supplier for global rail industry leaders including Siemens, Bombardier and Alstom.

To meet strict rail carriage welding standards, we’ve invested in top-tier IGM/KUKA welding systems for our production line.
