Stretch-Bend-Leveling Lines

Within the leveling process, Stretch-Bend-Leveling Technology
has the most effective outcome on thin metals. Various shape defects
such as waviness, crossbow, and coil sets are easily eliminated.

World market leader in the leveling technology for metal strips

The continuous development of stretch-bend-leveling lines has made b+s the world market leader in the leveling spectrum of thin and ultra-thin metals. By working in tandem, we subject the material to tension and bending. The material limits, such as yield strength, elongation, and spring bending set the parameters for what can be adjusted and for how internal stresses can be reduced. As a result, strip shape defects such as waviness, crossbow, the longitudinal bow and camber can be reduced to a minimum. These improvements in the strip’s quality significantly optimize downstream processing. As an example, the forming properties of the strip are improved, the shape accuracy of the end products is increased, and a thinner layer of surface coatings can be applied. Fewer coatings to cover up imperfections.
