Read MoreQuick ViewWhite 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 typeProcess 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.

Read MoreQuick ViewShock Absorber Steel Tube
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.

Applications of Hydraulic honed tubing
Honed tubing and SRB tubes (skived and roller burnished tubes) are mostly used as cylinder tube, such as hydraulic cylinder tube and pneumatic cylinder tubing, which are widely used for manufacturing and repairing hydraulic cylinders and pneumatic cylinders. As honed tube has very accuracy dimension tolerance and good surface smoothness, so this product is also used in applications where precision dimension or high smooth surface is need.
