What is Roll Forming?

A simple process ideal for even the most complex shapes

Well-suited for customized or standard shape production, roll forming is a flexible, responsive and cost-effective alternative to extruded press braking and stamping.

Efficient, effective shaping that delivers tight tolerances on complex profiles

Roll forming is a reliable, proven approach to metal shaping that is ideal for modern applications. This process uses a continuous bending operation where long metal strips, typically coiled steel, are passed through consecutive sets of rolls at room temperature. Each set of rolls performs incremental parts of the bend to produce the desired cross-section profile. Unlike other metal shaping methods, the roll forming process is inherently flexible, allowing secondary processes to be integrated into a single production line. For even the most demanding requirements, roll forming increases efficiency while reducing operational and capital costs by eliminating unnecessary handling and equipment.

Typical roll forming mills can accommodate material gauges ranging from .010" up to 0. 250" thick. The bend radius is largely determined by the ductility of the metal, but 180-degree bends are commonly achieved with the right material. Roll forming easily accommodates the integration of secondary operations such as welding, punching and precision laser cutting to optimize production efficiency.

Roll forming advantages

  • High-volume capacity
  • Ultra-precise processing to very tight tolerances with excellent part uniformity and superior surface finishes
  • More flexible and responsive than press braking or extrusion
  • Accommodates metals with variable surface coatings, flexibilities and dimensions
  • Processes higher-strength steels without breaking or tearing
  • Creates stronger and lighter structural components using less steel
