This product is a continuous hot-dip galvanized steel sheet, made of high-quality cold-rolled or hot-rolled base plate, processed through multiple precision processes such as pickling, annealing, hot-dip galvanizing, passivation and oil coating, which basically complies with the requirements of GB/T 2518-2019 national standard and international mainstream standards. The surface of the product is covered with a uniform and dense zinc layer, which has excellent corrosion resistance, good mechanical processing performance and beautiful surface texture. Through cathodic protection, the zinc layer can effectively isolate air and moisture from eroding the base plate, greatly extend the service life of the steel sheet and reduce the later maintenance cost. With outstanding cost performance, this product is widely used in construction, automobile, home appliance, machinery manufacturing and other fields. It can provide customized products with different zinc coating weights, surface structures and size specifications according to customer needs, adapt to various processing technologies such as stamping, welding and bending, and meet the use needs of various scenarios.
