Why is Gavanized Steel Sheet so Popular

Galvanizing of steel sheet is done by a process called “continuous hot-dip,” in which steel sheet is sank into a bath of molten zinc. The liquid zinc helps steel sheet to form a protective layer on steel sheet. The steel sheet can then be fabricated into other shapes with no flake or peeling off. The finished part resists corrosion without any additional or secondary painting or coating, making galvanized spinnings the most economical process for protecting steel from corrosion.

A large number of galvanized thin sheets are used in the fields of automobile manufacturing, refrigerators, construction, ventilation and heating facilities, and furniture manufacturing. Zinc plating has become an important method of steel corrosion protection, not only because zinc can form a dense protective layer on the steel surface, but also because zinc has a cathodic protection effect. When the galvanized layer is damaged, it can still prevent iron layer by cathodic protection.
