What is the procedure of coating with a thin layer of zinc to protect steel and iron from corrosion?

The process of coating steel or iron with a thin layer of zinc to protect it from corrosion is known as galvanization. Zinc acts as a protective barrier to prevent water and oxygen from reaching the steel or iron surface. Even if the zinc layer is damaged, zinc's sacrificial action prevents the underlying steel from corroding. Galvanization is commonly used for steel or iron pipes, outdoor constructions, and metal exposed to harsh environments.
