Cold rolling is a process that occurs after hot rolling in order to reduce the thickness, increase the yield and tensile strength and pliability of metal. It is a relatively expensive and labour-intensive process, but the improved mechanical properties increase the value of the finished product, whether that is a sheet, strip, or coil.
