Hot-dip galvanization - Wikipedia
Hot-dip galvanization is a form of galvanization.It is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 840 °F (449 °C). When exposed to the atmosphere, the pure zinc (Zn) reacts with oxygen (O 2) to form zinc oxide (), which further reacts with carbon dioxide (CO 2 ...Process·
