Advantages of cold–rolled steel coil:
1. The product size of cold-rolled coils is accurate, the thickness is uniform, and the thickness difference of the coils generally does not exceed 0.01-0.03mm or less, which can fully meet the requirements of high-precision tolerances.
2. Available to extremely thin strip that cannot be produced by hot rolling (the thinnest can reach 0.001mm or less.
3. The surface quality of cold-rolled products is superior, and there are no defects such as pits and pressed iron oxide scales that often occur in hot-rolled coils. And according to the requirements of users, it can produce coils with different surface roughness (glossy surface or hemp rough surface, etc.) to facilitate the processing of the next process.
4. The mechanical properties and technological properties of cold-rolled steel coils are very good (such as higher strength, lower yield limit, good weight deep drawing performance, etc.).
5. High-speed rolling and full continuous rolling can be realized, with high productivity.

The difference between cold–rolled steel and hot–rolled steel:
2.Properties: In general, the Mechanical Properties of hot and cold plates are considered to be the same in engineering, although there is a certain amount of work hardening during cold rolling, (but not rule out the case of strict mechanical performance requirements, it needs to be treated differently), cold plate usually than hot plate yield strength slightly higher, surface hardness is also higher, how specific need to see cold plate annealing degree. However, the strength of the annealed plate is higher than that of the hot plate.
3. Forming performance: Because the performance of cold and Hot Plate is basically not too much, so the forming performance of the influence factor depends on the difference of its surface quality, because the surface quality is the cold plate to be better, so generally speaking the same material steel plate, the appearance of cold plate is better than that of the hot plate.
