1. Cold-rolled steel coils are obtained from hot-rolled steel plates after a cold-rolling process and are surface-finished.

2. It is generally believed that there is no difference in the mechanical properties of hot-rolled steel plates and cold-rolled steel coils. However, cold-rolled steel coils have a certain degree of work hardening during the cold rolling process, so the yield strength of cold-rolled steel coils is slightly higher than that of hot plates, and the surface hardness is also slightly higher.

3. For steel plates of the same material, the cold plate has a better-forming effect than the hot plate.
