ROLLED STEEL STRETCHER LEVELING SERVICES

Achieve flat, stress-free material for your fabrication processes with stretcher leveling.

Stretcher leveling stretches material beyond its yield point in all fibers, equalizing internal stresses. This process produces flat material after laser cutting, notching, punching, or shearing operations. Unlike temper passing, which compresses the steel under massive pressure using rolling pins, stretcher leveling eliminates post-cutting stress springback, making subsequent processes like welding and forming easier.

Stretcher leveling systems employ a series of E-Drive Levelers to flatten and reduce crossbow (curvature) before moving to the stretcher. Clamps grab 40 feet of material at the stretcher and apply 2 million pounds of force, uniformly stretching it past its yield point. This method removes all internal stress, eliminating the risk of post-cutting springback.
