Yellow Galvanized Steel Tube

1. We use high quality raw materials. All raw materials are supplied from internationally known steel makers.

2. Each batch of raw material is 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 samplings.
5. Non-destructive testing and manual inspection for each tube ensure the 100% quality rate before galvanization

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.
