"Galvanized" refers to a process where metal, usually steel, is coated with a layer of zinc to protect it from rust and corrosion. This is typically done through hot-dip galvanizing, where the metal is submerged in molten zinc, or through electro-galvanizing, where zinc is applied using an electric current. The zinc coating acts as a barrier, preventing moisture and oxygen from reaching the underlying metal. The galvanized coating not only enhances the durability of the metal but also extends its lifespan, making it ideal for outdoor applications. Common uses of galvanized materials include fencing, roofs, and automotive parts, where resistance to weathering is essential.
