Cold rolled coil is made of hot rolled coil as raw material and rolled at room temperature below recrystallization temperature, including plate and coil. Which into the delivery of steel plate, also known as box plate or plate; Long length, delivery in coils called steel strip, also known as coil plate.

Specification: thickness 0.2-4mm, width 600-2000mm, length of steel plate 1 200-6000mm.

Performance: mainly used low carbon steel, requires good cold bending and welding performance, as well as certain stamping performance.

Cold rolled ordinary thin steel plate: made of ordinary carbon structural steel or low alloy structural steel cold rolled. The surface quality of cold rolled sheet is better. It has good stamping performance. It is required to ensure that the cold bending and cup test qualified, often used in automobile and other industries and coating board raw materials.

Cold rolled high quality thin steel plate: mainly includes all kinds of high quality cold rolled steel plate, the most commonly used is carbon structure steel plate, especially for deep stamping cold rolled thin steel plate, is made of low carbon high quality steel 08Al cold rolled thin plate, steel plate is divided into three groups according to the surface quality; ⅰ, ⅱ, ⅲ, respectively, denote specially advanced, advanced and higher finishing surfaces, which are divided into ZF, HF and F grades according to drawing grades (representing the most complex, very complex and complex parts used for drawing).According to the allowable deviation of steel plate thickness, it is divided into A, B two levels of accuracy, widely used in automobile and tractor industry.

Cold rolled steel plate: smooth surface, good processing, used for automobiles, refrigerators, washing machines and other household appliances, as well as industrial equipment, various building materials. With the development of economy, cold rolled steel plate has been called as a necessary material in modern society. Classification of cold rolling products: hot rolling pickling, hard rolling, ordinary cold rolling, galvanized (electric galvanized, fingerprint resistant, hot galvanized), aluminum zinc plating, tin plating, color coating, electrical steel (silicon steel sheet) and so on.
