  • The hot dip galvanization process begins by cleaning the steel to remove any contaminants, such as rust, oil, or dirt. After cleaning, the steel is submerged in a bath of molten zinc at approximately 450°C (842°F). The zinc reacts with the iron in the steel to form a series of zinc-iron alloy layers, which are then topped with a corrosion-resistant zinc layer. This method not only provides a tough, protective coat but also ensures a strong bond between the coating and the steel, resulting in a longer lifespan.
