Method
Along each length, features such as holes, slots, or embosses can be added, making the roll forming process a very cost effective method of achieving a strong, multi-functional shape. Roll forming is also well suited for Advanced High Strength Steel (AHSS) and Ultra High Strength Steel (UHSS), where material utilization is at a maximum.

Roll forming features
Benefits
- For large series roll forming is much more cost efficient than press brake bending
- Long lengths with very accurate tolerances can be achieved
- More complex profiles can be produced compared to press brake bending
- Sharper radii can be achieved through roll forming of high strength steel than during press brake bending
Drawbacks
- Not possible for few parts. Minimum a slit coil is needed
- High investment cost
- High cost for tooling
- Limited part size (width and depth) of the individual process line(s)
Recommendations
Roll forming is suitable for large series repeatable production with minimum volumes usually in excess of the equivalent of 20,000kg of parts from up to 800mm wide incoming strip feedstock.
