Hot Dip Galvanizing is the process of applying of Zinc Layer to iron and steel by passing the Metal through Molten Zinc at Temperature of Around 8600F (4600C). When exposed to the atmosphere, the pure zinc (Zn) reacts with oxygen (O2) to form zinc oxide (ZnO), which further reacts with carbon dioxide (CO2) to form zinc carbonate (ZnCO3), a usually dull grey, fairly strong material that stops further corrosion, protecting the steel below from the elements. Galvanized steel is widely used in applications where rust resistance is needed, and can be identified by the crystallization patterning on the surface (often called a “spangle”). The zinc coating protects the base metal by acting as an impervious shield between the metal and atmosphere and provides additional protection even when moderately sized areas of base metal surface are exposed.
We have set up State of the Art Facility to provide High Quality Hot dip galvanizing services to various fabrication units situated in South India, Our unit House some of the latest equipment’s for galvanizing.
