Customized Process Type for Scaffolding Pipe
1. Stamping / Embossing
The cost of embossing (the up one) is expensive than stamping (the bottom one). We usually choose stamping on the outside body of pipe. But for scaffold pipes, it is usually embossing.
2. Cut length
Cut gi pipes into shorter length 1m to 4.5m based on customer's requirements
3. Water proof bag / Plastic bag protection
Only pipe ends pvc packaged, only pipe body packaged or all packed.
