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
  • Embossing

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

Material Thickness & Lengths

Dahlstrom can currently form material thicknesses ranging from .012″ – .200″.
Dahlstrom can cut most shapes to specific lengths ranging from 2’ to 40’.


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.
