What is Roll Forming?

Roll forming is the process of gradually bending flat sheet metal into a longitudinal, uniform profile by passing it through a series of mated tool dies. It’s the most economical manufacturing process for the mass production of:

  • Angles

  • Channels (C, J, Box, Hat)

  • Long components with holes

  • Complex shapes with multiple bends

Roll forming also allows for the cheap, simple addition of IN-LINE punching features like:

  • Holes

  • Notches

  • Slots

  • Embossments

Designing these elements into custom tools eliminates the need for slow, expensive secondary operations. Consequently, roll forming lowers your production costs and reduces your lead times.

Tolerances

Many cross-sectional shape dimensions can be held within +/- .030″. Tighter and/or looser tolerances depend on customer requirements, processing capabilities, and tool investment.

Punched or Pierced Features

Depending on the complexity of a component, roll forming shapes like holes, notches, and cut-outs are either pre-punched in line or post-punched as a near-line secondary operation.
