In a single strand hot rolling mill finishing section a plurality of mufti- stand prefinishing rolling units are arranged along and are selectively shiftable onto and off of a first pass line segment. A mufti-stand finishing rolling unit and a mufti-stand post finishi ng rolling unit are arranged sequentially along a second pass line segment. A switch and associated delivery guides are selectively operable to direct products from the first pass line segment to the second pass line segment either at a location upstream of said finishing rolling unit, or alternatively, at a location between the finishing rolling unit and the post finishing rolling unit. With this arrangement, final rolling in the post finishing rolling unit may be precede d with or without rolling in the finishing rolling unit and with or without rolling in one or more of the prefinishing rolling units.
