20 High Cluster Mills utilize small diameter work rolls which allow higher reductions on harder materials than other mill configurations. The multi-roll system having employs a unique roll configuration with adjustment capabilities to control strip shape and compensate for the effects of rolling a wide range of different strip widths to very thin thicknesses.

A Z-Mill or Sendzimir Mill is a machine for rolling steel. Unlike a traditional rolling mill this 20-high cluster mill configuration utilizes cascaded supporting rolls to apply force on the small work rolls in the center. This allows the application of a higher roll pressure without bending the work rolls, which would result in poor metal quality.
