Cold galvanized steel grating is processed by cold galvanizing on the surface, and it is produced into the products required by customers. The mesh is flat, the mesh is welded evenly, there is no welding spot display, and the welding is firm. Its corrosion resistance is much different than that of hot-dip galvanizing. The price of electro-galvanizing is relatively cheap. Only one person can complete the installation of steel grating, which is simple and convenient.
