Galvanized steel grid external quality has uneven color, exposed white, impurities, bubbles (surface, middle, bottom), stratification, thickness deviation, insufficient curing degree, rich resin layer, cracking (curing, rich resin, mold), thimble defects, warping, repair defects and other defects, must establish a set of strict quality inspection standard system and specifications.
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.
