Galvanization Galvanization is a process in which a layer of zinc is applied to steel to protect it from corrosion. This is done by immersing the steel coil in a bath of molten zinc or by using an electroplating technique. The zinc coating creates a physical barrier between the steel and the surrounding environment, preventing rust and corrosion.
Color coating Once the steel coil has been galvanized, it can be further treated with a color coating. The color coating process involves applying a layer of paint or coating material onto the galvanized surface. This layer provides both aesthetic appeal and additional protection to the underlying steel.
The color coating can be applied using various methods such as coil coating, where the paint is applied to the entire surface of the coil, or by using a spray or roller coating technique. The coating material can be a combination of resins, pigments, and other additives that provide durability, weather resistance, and color retention.
