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).

Use of cold-formed steel members for construction of buildings started in both the United States and England in the 1850s. Use was largely experimental, and limited to a few basic structures.
