Cold Formed Sheet Metal

Cold forming sheet metal.

Cold formed sheet metal.

The former is a process used with sheet metal. A variety of steel thicknesses are available to meet a wide range of structural and non structural applications. Steel shrinks slightly as it cools. 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.

Since hot rolled steel is cooled after processing there is less control over its final shape making it less suitable for precision applications. The grob cold forming process is based on a straightforward and universally applicable principle. 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. For other forms such as bars or plates materials are sectioned and packaged.

Cold working is a metal forming method that has many advantages over hot working. The total forming effort needed is broken down into numerous forming increments spread along the entire cylindrical length of the zone being formed. 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 strength increase from cold work of forming has been incorporated for fl exural strength per section a7 2 of aisi s100 16.

The latter finds use with rectangular and round bars. No heat is required to form the shapes unlike hot rolled steel hence the name cold formed steel. Benefits very short forming cycles affordable tooling costs.
