Cold-rolled coils are a steel product produced by applying plastic deformation to hot-rolled steel on cold-rolling mills. With such processing, the product can have more accurate dimensional tolerances, better surface quality and improved mechanical properties as compared with hot-rolled coils. Cold rolling is also used to make thinner coils than hot-rolling mills can currently produce (less than 0.8-1.0 mm).

Cold-rolled coil classification, product range and properties

The standards applied in different countries to set the requirements for cold-rolled steel, such as EN 10130, EN 10268, EN 10209, ASTM A1008 / A1008M, DSTU 2834, GOST 16523, GOST 9045, GOST 17066 and others, specify steel grades and size ranges for cold-rolled coils, their application (profiling, cold forming, enamelling, general use, etc), mechanical properties, surface quality and other parameters.

Cold-rolled coils according to European standards

The most frequently followed European standards for producing cold-rolled coils are EN 10130, EN 10268 and EN 10209.

EN 10130 is applied to cold-rolled coils made of the low-carbon DC01, DC03, DC04, DC05, DC06 and DC07 steel grades for cold forming without coating, with a minimum width of 600 mm and a minimum thickness of 0.35 mm.
