Cold rolled coil product introduction

Cold-rolled steel sheet is a product produced by rolling hot-rolled coils at room temperature below the recrystallization temperature. It is widely used in automobile manufacturing, electrical products, etc. Cold rolling is rolling below the recrystallization temperature, but it is generally understood as rolling materials at room temperature.

During the production process, since heating is not performed, defects such as pits and iron oxide scale commonly found in hot rolling do not exist, resulting in good surface quality and high smoothness. Moreover, cold-rolled products have high dimensional accuracy, and their properties and structure can meet some special usage requirements, such as electromagnetic properties and deep drawing properties.

Cold-rolled thin steel sheet is the abbreviation for cold-rolled sheet of ordinary carbon structural steel, also known as cold-rolled steel sheet or simply cold sheet, which is sometimes mistakenly written as cold-pressed sheet. Cold sheet is made of hot-rolled steel strip of ordinary carbon structural steel, which is further cold-rolled into steel sheet with a thickness of less than 4mm. Since it is rolled at room temperature without generating iron oxide scale, the cold sheet has good surface quality and high dimensional accuracy. Coupled with annealing treatment, its mechanical and technological properties are superior to those of hot-rolled thin steel sheet. In many fields, especially in the home appliance manufacturing industry, it has gradually replaced hot-rolled thin steel sheet.

Our company's production specifications: thickness ranging from 0.15 to 2.5mm, and width ranging from 700 to 1250mm.
