Cold-rolled strip is used in a wide range of applications, such as automobile manufacturing, electrical products, rolling stock, aviation, precision instruments, food cans and so on. Cold-rolled sheet steel is short for cold rolled plate of ordinary carbon structural steel, also known as cold rolled plate, commonly known as cold plate, sometimes mistakenly written as cold tie plate. Cold plate is made of ordinary carbon structural steel hot rolled steel strip, after further cold rolling into a thickness of less than 4mm steel plate. Because of rolling at normal temperature, no oxide sheet is produced, so the surface quality of cold plate is good, the dimensional precision is high, coupled with annealing treatment, its mechanical properties and technological properties are better than hot rolled sheet steel, in many fields, especially in the field of household appliances manufacturing, has gradually replaced hot rolled sheet steel with it.
