When producing galvanized steel tubes, we use no-oxygen furnace to annealed the tubes which ensuire the smoothness of the inner and outside surface.Both the inner and outer surfaces of the high precision steel tubes can be galvanized or Zn only coated to the outside diameter,giving the tube a high homogeneity and an excellent rust resistant performance.
The length of these automotive steel tubes is 6000mm, the zinc color choices include white, yellow, and army green.
Dimension range: Outer diameter:6-76mm, wall thickness:1-10mm
Zinc wall thickness 8-12um, Salt spray test: common requirements: 80-120 hours, high requirements:120-300 hours,Cr+6 free, environmental friendly
Process Description
Using a high precision, fine drawn bright seamless steel tube as the steel pipe to make galvanization, the outer wall of the steel pipe is cold-galvanized, and both ends are covered for dust protection. The pipe length can be produced to be less than 6 meters.
Zinc color: White, yellow, dark green, and other options. After the galvanized steel surface is finished, the steel features an excellent rust resistance and corrosion resistance.
Primary purpose: These pipes are often used as automotive precision steel pipes, with a finish specifically for corrosion resistance as required by users.

- Precision in combination with a high quality surface finish are the features that characterise our fine tolerance steel tubing
- ERW feedstock tubes are manufactured from specially prepared pickled, oiled and cold or hot rolled steel coil.
- Resistance-pressure-welding Therefore, the weld is created from the base material without any filler material
- The removal of the excess material, both internally and externally, is a key element in the manufacturing process and this is an in-house skill.
- The cold drawing process occurs after annealing and raises the quality of the feedstock tube to vastly superior levels of tolerance, surface finish and final material mechanical properties.
- In some instances the final finished product specification can be further fine tuned by further annealing. This is of particular interest in relation to products that are specifically manufactured to unique customer specifications.
