Galvanized sheet is a cold-rolled steel strip as the substrate, through continuous hot dip galvanizing process and produced products, is a kind of excellent atmospheric corrosion resistance of the cross-layer steel plate, cold-rolled plate through the transition of catalpa, can extend the service life of 15-20 years. Product features: strong corrosion resistance, good surface quality, conducive to deep addition, economic and practical.
