Cold Rolled Steel

Cold Rolled Steel

Cold-rolled thin steel plate is the abbreviation of ordinary carbon structural steel cold-rolled plate, commonly known as cold plate. It is made of ordinary carbon structural steel hot-rolled steel strips, which are further cold-rolled into steel plates with a thickness of less than 4mm. Since rolling at room temperature does not produce iron oxide scale, the cold plate has good surface quality and high dimensional accuracy. Coupled with annealing treatment, its mechanical properties and process performance are better than hot-rolled thin steel plates. In many fields, especially In the field of home appliance manufacturing, the automotive field has gradually used it to replace hot-rolled thin steel plates..

Cold-rolled steel is processed from hot-rolled plates at room temperature. Cold-rolled steel plates have a smooth surface and excellent processing. They are used in automobiles, refrigerators, washing machines and other home appliances, as well as industrial equipment and various building materials. With economic development, cold-rolled steel plates have been called a necessary material in modern society. Hard rolled coils can be used as raw materials in hot-dip galvanizing plants because hot-dip galvanizing units are equipped with annealing lines. The weight of hard-rolled coils is generally 6 to 13.5 tons. The steel coils are continuously rolled on the hot-rolled pickled coils at room temperature. The inner diameter is 610mm.
