  2. Hot-dip galvanization - Wikipedia

    en.wikipedia.org/wiki/Hot-dip_galvanization

    Hot-dip galvanization. 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 450 °C (842 °F). When exposed to the atmosphere, the pure zinc (Zn) reacts with oxygen (O 2 ...
