3, Stable supply capacity

1. PRODUCT DETAIL:

1>. Technical Standard of White Zinc Coated Tubing:

White zinc coated tube uses copper coated double roll welded tubes as their base material. The tube surface is galvanized with a specified thickness of zinc, and then the passivation treatment is applied on the zinc coating layer. Corrosion resistance is increased with an added thickness of the zinc. This coating features good protection and can last more than 24 hours when exposed to salt mist testing.

2>.Plating: White Zinc

3>.Certifiction: ISO9001

4>.Package: cut-to-length /in coils, as your requirement.

5>.Standard: Country YB/T4164--2007

6>.Shape: round

7>.Raw materials: low carbon steel tube/ BHG2
