The 2030mm cold rolling production line was designed by German SMS. The main process equipment includes a continuous pickling line (strength level: Rm≤980MPa), a combined pickling and rolling line, and a continuous annealing line (strength level: Rm≤980MPa) 2 lines, continuous hot-dip galvanizing unit (strength level: Rm≤780MPa) 1 line. The annual output of commercial coils is 2.8 million tons, including 800,000 tons of hot-rolled pickled commercial coils, 1.6 million tons of cold-rolled annealed commercial coils, and 400,000 tons of cold-rolled hot-dip galvanized commercial coils. The products are mainly used in industires such as high- and mid-range automobiles and household appliances, etc.
