Rolling mill consisting of four rolls or known as a 4 High rolling mill is used for reducing material to extremely small thicknesses. Through the use of larger backup rolls, the issues of roll deflection can be avoided and smaller work rolls can be used. This reduction in work roll diameter: Reduces overall separating force required for reductions

Rolling mills have many different designs and may be stand-alone pieces of equipment used for processing plate or ingot, or incorporated into full processing lines used for coil-to-coil processing. To ensure outgoing material gauge meets a required dimensional tolerance, a rolling mill typically has very accurate positioning feedback.
