Cold rolled galvanized steel pipe Galvanized Steel round pipe
Cold galvanizing is also electro-galvanizing. This galvanizing method is used to protect metals from corrosion. For this reason, zinc filler coatings are used. After coating them on the protected surface by any coating method, they are dried. A zinc filler coating is formed, with a content of zinc (up to 95%) in the dried coating. It is suitable for repair work (that is, during repair work, only the place where the surface of the steel is protected is damaged, and the surface can be re-coated as long as the surface is repaired). The cold galvanizing process is used for the anticorrosion of various steel products and structures.

The zinc layer is relatively thin and the cost is low, which is suitable for short-term use or products with low requirements for corrosion resistance.Cold rolled galvanized steel pipe Galvanized Steel round pipe Equivalent Material
