Yes. Normally no effect can be detected on the section produced. In fact, we frequently use the rollformer as a ‘roll feed’, stopping to incorporate punching, notching and shearing or cropping within the one machine.
The section is governed by the accurately machined profile of hardened steel rollers and the setting of hardened infeed guides. These do not vary from one product to the next and hence give consistent sections for a given material thickness. Tolerances of +- 0.2mm are common.
