Cold Formed Sheet Metal

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.

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. For other forms such as bars or plates materials are sectioned and packaged. Technically cold working includes cold rolling and cold drawing. Cold working is a metal forming method that has many advantages over hot working.

For sheet metal rolled steel is spun into coils and left to cool. The former is a process used with sheet metal. The grob cold forming process is based on a straightforward and universally applicable principle. Steel shrinks slightly as it cools.

The latter finds use with rectangular and round bars. A variety of steel thicknesses are available to meet a wide range of structural and non structural applications. The most common shape for cfsf members is a lipped channel although z c tubular hat and other shapes and variations have been used. Since hot rolled steel is cooled after processing there is less control over its final shape making it less suitable for precision applications.

Cold forming sheet metal. Benefits very short forming cycles affordable tooling costs. No heat is required to form the shapes unlike hot rolled steel hence the name cold formed steel.
