TMW Stretcher Leveling: Perfectly Flat, Stress-Free Blanks
Stretcher Leveling beats roller leveling, tension leveling and even temper pass as the way to achieve 'stay flat' steel. Our Stretcher Levelers transform material with significant stress and edge wave into perfectly flat, stress-free blanks. We guarantee material processed on our Stretcher Levelers will beat temper pass CTL for flatness or the processing is free. In fact, it will achieve 1/4 of ASTM A568 Table 13 tolerance after laser cutting.
This is important for fabricators. Roller-leveled blanks may appear flat, but still contain stress. When the blank is cut or welded, that stress causes 'springback' which deflects the shape of the part and the blank. Blanks leveled on a TMW Stretcher Leveler have no residual stress, no springback. That makes fabricators more productive while reducing scrap.
