G90 Galvanized Coil-Zhongli（Shandong）Steel Group Co., Ltd.

G90 Galvanized Coil

Galvanizing is an economical and effective rust prevention method that is often used. About half of the world's zinc output is used in this process. Galvanized steel plate is to prevent the surface of the steel plate from being corroded to extend its service life. A layer of metal zinc is coated on the surface of the steel plate, which is called galvanized steel plate.
