Cold formed steel. Cold-formed steel (CFS) is the common term for products made by rolling or pressing thin gauges of sheet steel into goods.
Cold-formed steel goods are created by the working of sheet steel using stamping, rolling, or presses to deform the sheet into a usable product. Cold worked steel products are commonly used in all areas of manufacturing of durable goods like appliances or automobiles but the phrase cold form steel is most prevalently used to described construction materials. The use of cold-formed steel construction materials has become more and more popular since its initial introduction of codified standards in 1946. Caucho etileno-propileno-dieno. Polyvinyl alcohol.
