Cold formed sheet metal.

Cold formed steel cfs members are made from structural quality sheet steel that are formed into c sections and other shapes by roll forming the steel through a series of dies. No heat is required to form the shapes unlike hot rolled steel hence the name cold formed steel. A variety of steel thicknesses are available to meet a wide range of structural and non structural applications. Since hot rolled steel is cooled after processing there is less control over its final shape making it less suitable for precision applications.

Technically cold working includes cold rolling and cold drawing. The former is a process used with sheet metal. Where aisi s100 16 is referenced it is the north american specifi cation for the design of cold formed steel structural members 2016 edition with us provisions. The total forming effort needed is broken down into numerous forming increments spread along the entire cylindrical length of the zone being formed.

The latter finds use with rectangular and round bars. The most common shape for cfsf members is a lipped channel although z c tubular hat and other shapes and variations have been used. Cold formed steel framing cfsf refers specifically to members in light frame building construction that are made entirely of sheet steel formed to various shapes at ambient temperatures. The strength increase from cold work of forming has been incorporated for fl exural strength per section a7 2 of aisi s100 16.

For sheet metal rolled steel is spun into coils and left to cool. The grob cold forming process is based on a straightforward and universally applicable principle. For other forms such as bars or plates materials are sectioned and packaged.
