Red Bud Industries has developed a Stretcher Leveler capable of producing panel flat blanks at material thicknesses up to 1/2" (12.7 mm) at yield strengths up to 75,000 PSI (517.1 N/mm²) or 3/8" (9.5 mm) at up to 100,000 PSI (689.4 N/mm²). This new machine is the third generation of Red Bud's existing Stretcher Leveling System. Previous machines were limited to a maximum thickness of .135" (3.4 mm) and .312" (7.92 mm).
The Stretcher Leveler stretches the material sufficiently to exceed the yield
point in all the fibers of the strip from top to bottom and from edge to edge
thus equalizing internal trapped stresses throughout the material. In addition,
the Stretcher Leveler will produce the ultimate in flatness effectively removing
edge wave and center buckle from the material.

The end result is flat material that stays flat even after laser cutting, notching, punching, or subsequent shearing operations. This new Stretcher Leveler exceeds the capabilities and produces better product than Cut-To-Length Lines utilizing Temper Mills at a much lower cost. Besides providing "dead" flat blanks for use in critical cutting and welding applications, the Stretcher Leveler can be used to efficiently reclaim secondary material and convert it to prime.
