WebbThe galvanization process is a way of protecting metal by coating it with zinc. Galvanization is a chemical process in which zinc ions are dissolved in molten zinc. The zinc is then spread evenly across the surface of the metal, where it cools and hardens to form a protective barrier. This corrosion-resistant coating is galvanized steel! WebbTypically, the process of the surface preparation of galvanized iron pipes operates as follows: Firstly, the steel is cleansed with the use of a caustic solution — a corrosive substance in where it will completely remove all oil, grease, dirt, and excess pain. After the caustic solution is rinsed off, the iron pipe is then pickled.

WebbGalvanization with Zinc is a commonly used method to increase the corrosion resistance of steel (Zn galvanizing) [1,2].
