Abstract: The invention relates to a method for rolling a metal product (1), wherein the metal product is subjected to a rolling operation at a first station (2), which rolling operation is controlled by a control device (3), wherein the product (1) is subject to a measurement at a second station (4), wherein the product (1) is subjected to a further processing operation at a third station (6), and wherein the product (1) is in a specified quality at a fourth station (7). In order to increase the quality of the produced strip, the invention provides that the method has the following steps: a) measuring the value of a material property (IW) that the second station (4); b) feeding the value measured at the second station (4) to the control device (3), comparing the measured value with a value (SW) stored in the control device (3), and adjusting a parameter (PPI) if the measured value deviates from the stored value (SW), e) measuring a value of a quality material property (Q) at the fourth station (7); d) comparing the measured value with a stored value, and initiating a measure to influence the quality material property (Q) if the measured value deviates from the stored value beyond a permissible tolerance.
