Roll forming is a manufacturing process by which large strips of sheet metal, usually steel, are pushed through two or more large roller drums in order to achieve a specific contour. These roller drums are usually mounted on a pair of horizontal shafts that can help control the distance between the rollers and the shape of the final product. This is a popular process used to create a large quantity of parts with contour-specific profiles.

Computer simulation is an important aspect of roll forming because it allows the manufacturer to set specific guidelines for the rolls with the least amount of waste. In general, the rolls are designed in a flower shape pattern that can be manipulated to achieve different sizes and types of bends in the material. Furthermore, simulation software is an important investment for mills that are required to produce different shapes and sizes because it can reduce the changeover time required to adjust the rolls to different settings.

There are a variety of roll forming machines available to create different sizes and shapes of sheet metal. In general, many of these machines use the same rollers to create different shapes and thicknesses by adjusting the distance between the rollers.
