Hotdip galvanization Wikipedia
Hotdip galvanization is a form of 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 449 #176;C (840 #176;F). 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
