Cold rolling technology originated in Germany in the mid-19th century and was initially used to produce cold-rolled strip steel with a width of 20 – 25 mm. So, what is cold rolled steel? The following will introduce cold rolled steel in detail from aspects such as its definition, production process, performance characteristics, and application fields:<\/p>\n
