The consistent further development of stretch-bend-leveling lines has made b+s the world market leader in the leveling of thin and thinnest metal strips.

By superimposing tension and bending during the straightening process, material parameters such as yield strength, elongation and spring bending limit can be adjusted and internal stresses reduced. As a result, strip shape deviations such as waviness, the cross bow, the longitudinal bow and the camber are reduced to a minimum.

These improvements in strip quality significantly optimize further processing. For example, the forming properties of the strip improve, the shape accuracy of the end products is increased, and thinner layer thicknesses can be achieved for surface coatings.
