White galvanized steel tubes
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
Process Description
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.

1. We use high quality raw materials. All raw materials are supplied from internationally known steel plants.
2. Raw materials are checked for both chemical and mechanical properties, according to specifications.
3. During the cold drawing process, our inspectors check every bundle three times: once at the beginning of the process, once during the middle, and finally, at the end of the cold drawing process.
4. During the final heat treatment, every bundle has the surface checked, as well as mechanical properties through sampling.
5. Non-destructive testing machinery and manual inspection ensure the 100% quality rate.

Shock absorber precision steel tubes are suspension components that are responsible for absorbing the impact of avehicle’s movements. Through the shocks, the vehicle’s bounce cycle is cut short. If the car encounters abump on the road, it will still bounce; however, the shocks will shorten its bounce so that the driver and passengers will hardly feel it.
