Customized Process Type for Galvanized Steel Pipe
1. Stamping / Embossing
The cost of embossing is expensive than stamping. We usually choose stamping on the outside body of pipe.
2. Threaded ends / Socketed & plastic cap protection
BSP threaded and NPT threaded with coupling separately on one end and cap on the other end.
3. Grooved ends
Grooved ends gi pipes are connected by coupling. If you need coupling we can supply separately.
4. Bending / Arched
Bending gi pipes are usually used in greenhouse structure.
5. Water proof bag / Plastic bag protection
Only pipe ends pvc packaged or all packed.
