During the galvanization process, the prepared steel tank panels are completely immersed in hot liquid zinc, which completely covers the surface and bonds with the iron in the carbon steel to form several iron/zinc alloy layers. This allows the zinc to become part of the surface of the steel, protecting the steel from both the atmosphere and corrosion. The hot dipped process provides better durability then then electrogalvanation process which provides a significantly thinner lay of zinc alloy. The formation of insoluble basic carbonate films on the surface of the zinc protects it against the environment. All of our hot-dipped galvanized storage tanks adhere to the requirements of ASTM A123, which outline the guidelines for coating thickness, finish, appearance and adherence.
