What is Galvanization?
Hot-dip galvanizing involves coating iron or steel with a layer of zinc by immersing the metal in a bath of molten zinc at a temperature of about 450°C (842 ° F). During the process, a metallurgically bonded coating is formed that protects the steel from harsh environments, whether outside or inside. Galvanizing.
