CR180B2 Prepainted Hot Dip Galvanized Steel Sheet Coil

CR210B2 CR180B2 CR210BH2 Galvanized steel Coil/Sheet is to prevent corrosion on the surface of the steel plate to prolong its service life, a layer of metal zinc is plated on the surface of the steel plate, and the galvanized steel plate is called galvanized plate.

Galvanized steel coils are coated with a zinc layer because rust does not corrode this protective metal. The outermost layer is all zinc, but the successive layers are a mixture of zinc and iron, and the interior is pure steel. These multiple layers are the reason why metals have amazing properties that are resistant to corrosive environments.

Zinc also protects the steel by acting as a "sacrificial layer". If the surface of the galvanized steel coil does rust, the zinc will corrode first. This allows the zinc to spread over the nicks or scratches to prevent rust from reaching the steel. For countless outdoor, marine or industrial applications, galvanized steel coil is an essential manufacturing component.
