The hot galvanized plate immerses the thin steel plate into the melted zinc tank, making it nominally adhere to a layer of zinc thin steel plate. It is important to adopt the continuous galvanizing process to produce galvanized steel plates, that is, the rolled steel plates are continuously immersed in a galvanized plating tank to make galvanized steel plates. Alloyed galvanized steel plate. This type of steel plate is also made by hot immersion, but immediately after it is out of the tank, it is heated to about 500 °C, making it a alloy film of zinc and iron. This galvanized plate has excellent coating compactness and weldability.
