The galvanizing production line applies United States steel corp’s hot-dip galvanizing technology. Taking the cold-rolled substrate as the raw material, the finished product is formed through cleaning, drying, reduced annealing, galvanizing, cooling, finishing, tension levelling and passivating and coiling. The production line is continuous, precise, large-scale and high in automation level. The product is widely used for industry, agriculture, construction industry and other fields. The galvanized steel plate surface has high corrosion resistance, high strength, easiness in machining and other characteristics. The plating of the hot-dip galvanizing product includes pure plating and alloying plating. Generally, the product is delivered in the coiled form. The company, which is excellent in equipment configuration and strong in technical forces, possesses one galvanizing production line with annual productivity up to 100,000 tons, which can produce galvanized sheets with various specifications of 0.10?1.20x700?1250xC, in which the ultra-thin large spangle galvanized sheet of 0.10?0.15x1000xC lies in the international advanced level, filling domestic blank with its incomparable advantage.
