Roll forming is a continuous metal forming process that gradually bends flat sheet metal into a longitudinal, uniform profile by passing it through a series of precision roll stations.

Because the material remains in motion throughout the process, roll forming is ideal for producing high volumes of consistent, repeatable parts.

Unlike press braking or stamping, roll forming distributes deformation across multiple forming passes.

Each roll station makes a small, controlled adjustment to the profile until the final geometry is achieved.

Roll forming turns a coiled strip of sheet metal into the desired shape by passing that metal through a progressive series of mated dies.

Roll forming is a cost-effective way to achieve the production of long, complex metal shapes with multiple bends and/or punch patterns. It is popular for high-volume projects like:

• Solar panel racking
• Bus bars & wire raceways
• Elevator/escalator components
• Shelving supports

You see roll formed products all the time. For example, guide rails on the highway are usually manufactured using this metal fabrication method.
