Leading manufacturers typically offer a range of galvanizing processes, such as hot-dip galvanizing or electro-galvanizing. Hot-dip galvanizing involves immersing the metal in molten zinc, resulting in a thicker coating that provides superior corrosion resistance. On the other hand, electro-galvanizing applies a thin layer of zinc through an electrochemical process, often resulting in a more polished finish, but may not offer the same level of protection as hot-dip galvanization.
