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).
Cold rolled sheets can be worked into various thicknesses, while shapes require sizing, roughing and finishing. Cold rolled steel is superior in tolerance, strength, straightness and finish when compared to hot rolled steel. Appearance and Use: Cold rolled steel is grey in appearance and is smooth to the touch. Products commonly cold-rolled include strips, sheets, bars and rods, which are usually smaller than their hot rolled counterparts.
