Sep 11, 2014 · Customers often ask us about the differences between hot rolled steel and cold rolled steel.There are some fundamental differences between these two types of metal.The differences between hot rolled steel and cold rolled steel relates to the way these metals are processed at the mill, and not the product specification or grade.
Hot rolled and cold rolled are the process of steel plate or profile forming. They have a great influence on the structure and performance of steel.. The rolling of steel is mainly hot rolling, and cold rolling is usually used only for the production of steel with precise sizes such as small-sized section steel and thin plates.
