Hot Dip Galvanizing, as a method of corrosion protecting for steel, has grown almost continuously since it was first used over 150 years ago. Its ability to grow in the face of sophisticated competition is the result of the simplicity of the process and the unique advantages of the coating.
Galvanizing can only be performed on chemically clean surfaces. Therefore most of the preparation work is done with this objective in mind. The substrate will usually be dipped in a dilute acid solution to remove all traces of surface oxide such as rust and mill scale. After rinsing, the work is then dipped in a flux prior to galvanizing.
