Answers to Frequently Asked Questions about cold Roll Forming

Why Roll Form?

Roll forming is a continuous metal forming process that transforms sheet, strip or coiled metal into shapes with a consistent cross section. The stock is fed through successive pairs of rolls, which progressively shape the metal until the desired cross section is produced. Only progressive forming (bending) takes place; the metal thickness is not changed except for a slight thinning at the bend radii.
