The galvanization process can be carried out through different methods, including hot-dip galvanizing and electro-galvanizing. Hot-dip galvanizing involves immersing clean, molten zinc baths in iron or steel articles, allowing for a thick external layer to form. This method offers excellent durability and longevity, making it suitable for outdoor applications. Meanwhile, electro-galvanizing employs an electric current to apply a thinner zinc coating, providing a smoother finish that is often used for applications requiring more aesthetic appeal.
