Roll Forming Process

Roll forming is a continuous deformation process to obtain profiles from both aluminum and steel strips.
A passages sequence of the strip into a set of forming rolls stations allows getting a given geometry.

Advantages of Roll Forming

  • Processing of different materials.
  • Tight tolerances.
  • CNC process.
  • Robustness and repeatability.
  • Flexibility and reliability.
  • Efficiency in production.

Integrated Processes

A strength point of the Emarc Group is the ability to combine and integrate all processes necessary to obtain a finished product into a “Universal Production Line”.
Production lines are developed, designed and built by Emarc and transferred after try-out to the production sites worldwide.

Example of a universal production line
