In roll forming, each roll stand progressively shapes the metal tube closer to the desired profile, allowing continuous production. The more stands there are, the more complex the profile can be. In this article, we'll cover how roll forming is used to create common complex profiles, including U-channels, box channels, multi-bend, custom ...

Since the roll tooling can only rotate at the exact speed of the material at one point on the profile (such as located on the web of a channel section), the flange rollers that form the vertical features are larger in diameter than at the drive point on the cross section and therefore have a greater surface speed than the material itself ...

The roll forming line was producing a good profile, well within industry-standard straightness tolerances of 0.015 in. per foot of length, both for bowing and camber. Unfortunately, the application demanded extraordinarily tight camber control—less than 0.25 in. on a 40-ft.-long part.

Roll Forming a Tube. Now let's roll form the same 2-in.-diameter tube with prepunching. The process requires 10 passes before the welding station, because a typical roll former doesn't have idler stands. Tube and pipe mills use idlers between almost every pass to assist in forming the round.

for web panels would result in low web re-sistances in shear and bending; the overall resistance of the girder would therefore be reduced. From the above, the primary role of interme-diate web stiffeners is clear: they serve to divide the web into panels and thereby re-duce the web panel aspect ratio. This increases web resistance.
