Galvanized Steel

Hot dipped galvanized steel is widely used for roofs,outer walls,ovens,explosive-proof steel,electrically controlled cabinets, and industrial freezers in the residential and industrial buildings.Galvanized steel plate and coil is the process of coating steel surface with a layer of zinc by immersing the metal in a bath of molten zinc at a temperature of around 860 °F (460 °C). 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 in many circumstances, protecting the steel below from the elements.
