Roll forming is a process in which a strip or sheet of metal, such as steel, is passed through a continual set of stands (rolls) until the desired crosssection profile is achieved. The sheet or strip is plastically deformed along a linear axis in a room temperature environment. Typically used to create parts featuring long lengths, roll forming is also useful for manufacturing large ...

The most predominant type of rolling is the flat rolling operation. This technique allows feeding material in between two rollers rotating in opposite directions as depicted in Fig. 4, with the spacing between the rollers designed smaller than the thickness of the initial material to compressed it into the desired thickness [14].The deformation process causes elongation of the material.
