Hot-rolled coils can also be called hot coils, which are strips made of slabs (mainly continuous casting slabs) and heated by rough rolling units and finishing rolling units, generally including medium-thick and wide steel strips, hot-rolled Rolling thin wide steel strip and hot rolled sheet.

Carbon steel coils can be divided into hot-rolled coils and cold-rolled coils according to the production process. Cold-rolled coils are made of hot-rolled coils and rolled below the recrystallization temperature. Common grades are: SPCC, SPCD, SPCE, ST12-15, DC01-06.

Hot-rolled coils can also be called hot coils, which are strips made of slabs (mainly continuous casting slabs) and heated by rough rolling units and finishing rolling units, generally including medium-thick and wide steel strips, hot-rolled Rolling thin wide steel strip and hot rolled sheet.

Cold rolling is rolling under recrystallization, but it is generally understood as rolling using normal temperature rolling materials. Since cold-rolled coils are not heated during the production process, there are no defects such as pitting and scale that often occur in hot rolling, and the surface quality is good and the finish is high. Moreover, the dimensional accuracy of cold-rolled products is high, and the performance and structure of the products can meet some special requirements for use, such as electromagnetic properties and deep drawing properties.
