Cold-formed steel (CFS) is the common term for products made by rolling or pressing steel into semi-finished or finished goods at relatively low temperatures (cold working).
Hot rolled steel is rolled or shaped at a high temperature while cold rolled steel is rolled at room temperature. Cold rolled has a smooth and shiny finish while hot rolled has a grey and scaly finish. Cold rolled has sharper corners and more precise dimensions than hot rolled.
