The Straightener is a precision device used after roll forming to fine-tune the flatness, linearity, and cross-sectional integrity of cold-formed profiles. By using multi-roller calibration, it eliminates residual stresses, slight twists, or bending distortions—ensuring every profile meets tight dimensional tolerances and application-specific accuracy standards.
In high-end cold roll forming lines, dimensional consistency does not end at forming—it continues with finishing. The Straightener is designed to correct minor deformations caused during forming, cutting, or thermal effects, especially in long or slender profiles.
Using multi-pass roller adjustment, it gradually corrects:Profile camber (horizontal bending),Bowing or wave (vertical distortion),Twist or torsion in open/closed sections
Ideal for applications where precise fit and installation quality are essential—such as structural systems, enclosures, support rails, and construction profiles.
This post-forming device improves not only product quality but also customer satisfaction, reducing the need for rework or field adjustments.
