A method for rolling rolled strips 3, 4 in a hot strip rolling mill 6, comprises at least two roll stands 6, 7, with horizontally adjustable top and bottom work rolls 10, 11. Each work roil is backed up directly or through an intermediate roll by a backup roll 9 or in a reversing stand where at least two passes are rolled, wherein the roll strip is subjected to a condition control for which profile the surface evenness-imparting correctively control elements act upon the rolled strip to meet requirements of profile accuracy and surface evenness of the rolled strips in spite of flexible rolling program if a target contour of the profile of the rolled strip 3, 4 is preset for achievement of which two groups of correction control elements act successively upon the rolled strip. The control elements 12, 13 of first group are brought to bear if a rolled strip thickness is above the critical thickness and influence largely the contour of the rolled strip in its central region referred to the strip center. The control elements 12, 13 of the second group are brought to bear in the strip edge region if rolled strip thicknesses below the critical thickness.
