Tension Leveling is the process of pulling the strip beyond its yield point to permanently change the shape of the strip and make it flat. If you have an edge wave, the concept is to stretch the shorter fibers in the center of the strip so that they will match up in length with the longer fibers from the edge wave.
Conversely, if you have a full center, you are attempting to stretch the edges of the strip to match up in length with the center buckle. If the strip is consistent in length across the width of the strip, you have created flat steel. The tension leveling process is a combination of elongating the strip and bending the fibers over a series of work rolls. Tension leveling will eliminate edge wave and center buckle as well as correct excessive crossbow and coil set.
Should the width of your material need to be changed, we can remove as much a 3″ of material per edge with our inline side trimmers, eliminating the need for additional processing.
