The galvanized coils is defined as a carbon steel sheet coated with zinc on both sides. A zinc coating is one of the most effective and economical methods of protecting bare steel from a corroding environment. The zinc not only serves as a barrier between the steel and the environment, but it will also sacrifice itself to protect the underlying steel sheet.
Spangle：
Galvanization or galvanizing is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The size of crystallites (grains) in galvanized coatings is a visible and aesthetic feature, known as “spangle”.
Zinc Coated：
With the cold-rolled steel of different strengths and thickness as substrate. it is produced by applying the zine coat on both faces by hot-dip process.
