Cold Formed Sheet Metal

Since hot rolled steel is cooled after processing there is less control over its final shape making it less suitable for precision applications.

Cold formed sheet metal. For other forms such as bars or plates materials are sectioned and packaged. 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. 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.

Technically cold working includes cold rolling and cold drawing. Steel shrinks slightly as it cools. Cold forming sheet metal. A variety of steel thicknesses are available to meet a wide range of structural and non structural applications.

The total forming effort needed is broken down into numerous forming increments spread along the entire cylindrical length of the zone being formed. The grob cold forming process is based on a straightforward and universally applicable principle. No heat is required to form the shapes unlike hot rolled steel hence the name cold formed steel. The most common shape for cfsf members is a lipped channel although z c tubular hat and other shapes and variations have been used.

Benefits very short forming cycles affordable tooling costs. 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.
