Roll Forming: Precision and Efficiency for Long, Consistent Profiles​

Roll forming is a continuous bending process that transforms long strips of sheet metal into precise, desired cross-sections. This is achieved as the strip progressively passes through a series of roller sets, each incrementally shaping the metal until the final profile is formed. This method is exceptionally well-suited for producing high volumes of long parts with consistent cross-sections.​

Integrated Punching and Cutting Capabilities:​

Our roll forming lines are highly configurable to integrate punching and cutting operations, enabling continuous production.

  • Cutting to Length:
    • Pre-cut die: A single blank is cut to length before entering the roll mill.
    • Post-cut die: The profile is cut to length after the roll forming process is complete.
  • Adding Features: Holes, notches, embossments, or shear forms can be precisely added to parts through punching. This can occur at various stages within the roll forming line:
    • Pre-punching: Features are added before the roll forming begins.
    • Mid-line punching: Punching occurs during the roll forming process.
    • Post-punching: Features are added after the roll forming is finished.

Some roll forming lines may incorporate a single punching or cutoff application, while others integrate multiple or all of these applications into one streamlined line.​
