Hot Dip Galvanizing

Hot Dip Galvanizing is a process by which steel is coated with molten zinc for lending it long-term resistance to any form of corrosion. First of all, the steel is chemically cleaned of impurities like oil, rust and surface mill scales. Once the cleaning process is done, the steel is then prepared for the coating process. A bath of molten zinc heated to around a temperature of 460C is prepared and the zinc is then carefully immersed in the bath. After this stage, the steel is removed from the molten bath and shifted to a quench tank for cooling. Zinc coating is finally metallurgically bonded to the treated steel.
