When producing galvanized steel tubes, we utilize advanced technical processing and use a chemical liquid imported from Germany. Both the inner and outer surfaces of the high precision steel tubes can be galvanized, giving them a high homogeneity and an excellent rust resistant performance.
Zinc wall thickness 8-12um, and customized as per customer requirements. Salt spray test: common requirements- 80-120 hours, high requirements- 120-300 hours Cr+6 free, environmental type
Using a high precision, fine drawn bright seamless steel tube as the steel pipe for galvanizing, the outer wall of the steel pipe is cold-galvanized, and both ends are covered for dust protection.
