Galvanizing is a process used to protect metal, particularly steel, from rust and corrosion. It involves coating the metal with a layer of zinc, which acts as a barrier against moisture and oxygen. This protective layer helps extend the lifespan of metal products, making them more durable in various environments. The most common method of galvanizing is hot-dip galvanizing, where the metal is submerged in molten zinc. This creates a strong bond between the zinc and the metal surface. Galvanized materials are widely used in construction, automotive, and outdoor applications due to their enhanced resistance to environmental damage.
