A roll for rolling metal products has at least one roll neck (2). In order to provide for recognition of the roll, during its circulation in a plant for regrinding, an identification code for the roll, which is readable by a reading apparatus, is provided on the end surface of the neck (2), the code being formed by removal of material from the neck at a predetermined location or locations so as to define, together with un-removed material, elements (3) of the code. A binary code formed by concentric grooves (3) is used. |
