Galvanized steel pipe(galvanized pipe), Galvanised steel pipe(galvanised pipe)
Galvanized steel pipes are made of steel that has been covered with a layer of zinc metal. During the galvanizing process, we immerse the steel in a molten zinc bath, ensuring a tough, uniform barrier coating.

Application:
1.Building and structural material
2.Mechanical and general engineering purposes
3.Manufacturing of Bus Body, Railway Boogies
4.In Telephone department as Conduit Pipes
