Z120 grade galvanized steel coil is coated with zinc to make it more durable. The process works by dipping the coiled steel sheet into a galvanizing bath filled with molten zinc. Galvanized coils are obtained by subjecting thin steel sheets to a continuous galvanizing process. This type of steel has better formability and good paint adhesion for commercial or architectural purposes. Another way to produce galvanized steel sheets is through the hot-dip process. In this method, it is crucial that the steel sheets are heat treated at 500°C immediately after exiting the can to form an alloy film coating.
The primary advantage of galvanized steel is the strong resistance against corrosion. The zinc coating protects the underlying steel against the harsh elements of the environment.
