BUCKLING BEHAVIOUR OF COLD FORMED STEEL SECTIONS
structural steel sheets by bending or forming into different shapes by roll forming the steel through a series of dies. The advantage of cold formed sections is that, no heat is required to form the shapes unlike hot-rolled members. CFS does not shrink or split, doesn't absorb moisture and also resists warping, termites and fire.

The basics of roll form tooling design
Side rolls, or rolls that are mounted on a vertical axis and located between passes, are excellent for helping a profile enter the main roll passes. In addition to smoothing out the forming transition between passes, side rolls also reduce scuffing of the vertical legs because they spin on the same axis that the profile travels.
