It also depends on obtaining the required organization (such as various textures, etc.) and required cold rolled steel coil properties (such as deep drawing, electromagnetic properties, etc.) according to the technical requirements of the product. Finishing includes inspection, cutting, straightening (flattening), printing, sorting and packaging, etc.
