Cold CRC Rolled Steel Coils

Cold rolled steel coil is a steel coil product made by cold processing of hot rolled coil or plate at room temperature.Compared with hot rolling, cold rolled steel coils usually have higher flatness and surface quality, and their mechanical properties and dimensional accuracy are better. Cold rolled steel coil is directly rolled into a certain thickness by rollers at normal temperature and rolled into a whole coil by a winder. Compared with hot rolled coil, cold rolled coil has bright surface and high smoothness, but it will produce more intemal stress, SO it is often annealed after cold rolling.  Commodity Cold rolled Steel Coil Grade SPCC,SPHC,SPCD,ST12,ST13,DC01,DC03,DC04 Standard ASYM,JIS,EN,GB,BS,AISI,GOST Mechnical Commercial /Drawing/Deep Drawing /Extra Deep Drawing/Structural quality…
