Roll forming is a continuous metal shaping process used to make a variety of corrugated metal products. During this process, a sheet of metal is passed through several rollers that are specially shaped. The metal is then molded into certain shape to be used in a variety of ways. The settings of the rollers bend the strips of metal sheeting to contour the metal. Some of the shapes used in roll forming can include angles, c-shapes, and u-shapes. Metal can also be pressed flat or made into hollow shaped tubes or open shaped tubes.

The roll forming machine used in this process is able to press together large metal sheets or rolls through two sets of rollers to form the materials with almost identical cross sections. During the process of making roll forming metal, the machine will feed the metal between consecutive pairs of rolls with increasing shape. It will bend and shape the material to the correct configuration. This will add both the desired strength and rigidness to the metal materials being used.

Many types of metals are suitable for the roll forming process. These include composites, ferrous metals such as those mostly made of magnetic metals like iron and steel and metals such as aluminum, brass, copper, lead, zinc and tin. Plated along with non-plated surfaces can also be shaped using a roll forming machine.

During roll forming, the forming maching can achieve a desired pattern can be achieved by pressing a metal blank with dies into a certain shapes. The stamping process uses mechanical or hydraulic powered presses. These presses are then fed successive strips of metal or single blanks. The strips are positioned in the press and shaped by the tooling. This causes the powerful stamping action that makes the pattern on the metal.
