Zoom-Mill™ | Steel Plantech

Zoom-Mill™ rolling improves off-gauge rolling ratios by 1% as compared to conventional rolling mills. In the case of 6-pass rolling, the length of the off-gauge portion of the coil periphery will usually be more than 10 meters. However, the use of the Zoom-Mill™ rolling method will enable a finish with the off-gauge at less than 2 meters.
