Our cold-rolled high-quality thin steel plates include various carbon structural steel grades, particularly deep-drawing cold-rolled thin plates made from low-carbon high-quality 08Al steel. Quality is categorized into three groups representing premium, high-grade, and superior finish surfaces.
Smooth surface and excellent processing characteristics make these plates ideal for automotive, home appliances (refrigerators, washing machines), industrial equipment, and building materials.
Manufacturing includes pickling, cold rolling, degreasing, annealing, leveling, and shearing processes.
We provide slitting services to cut cold rolled steel coils into strips of various widths, folded into small coils for transformer, motor, and metal strip applications.
