  • Cold-formed steel

    Cold-framed steel (CFS) is the normal term for steel items formed by cool working procedures done close room temperature, for example, moving, squeezing, stepping, twisting, and so on. Stock bars and sheets of cold-moved steel (CRS) are generally utilized in every aspect of assembling. The terms are against hot-framed steel and hot-moved steel.

    The major forming processes are carried out hot, at about 1,200° C (2,200° F), because of steel’s low resistance to plastic deformation at this temperature. This requires the use of reheating furnaces of different designs. Cold forming is often applied as a secondary process for making special steel products such as sheet or wire.
