RAILWAY AND INFRASTRUCTURE TUBING

Safety-critical tubes for rolling stock.

Global Seamless is an RDSO-registered vendor for air brake pipes — the safety-critical cold-drawn seamless tubes that form the braking system of every coach and wagon on Indian Railways. We also supply structural hollow sections, boiler tubes, and fluid pipes for rolling stock manufacture and railway infrastructure projects.
All railway tubes are manufactured through the cold-drawn seamless process with RDSO-witnessed inspection, full material traceability, and compliance with RDSO specification 02-ABR-94.
