A metal band product rolling installation comprising at least two rolls with parallel axes inside a fixed holding stand (1) having two separate standards (11a, 11b) each forming a closed frame comprising two stiles (12 12'), an upper crossbeam (16) and a lower crossbeam (16'), and delineating a center window (6), at least one of the rolls being a back-up roll (3), carried by two supporting parts (4a, 4b) each resting on a back-up face (63) of the corresponding crossbeam (16 16') of each standard (11a, 11b). According to the invention, at least on one side of the rolling plane (T1), the crossbeam (16) of each standard (11a, 11b) is fitted with a back-up face (63) exhibiting, over the whole width of the window (6), a concave rounded profile extending on an angular sector of at least 180.degree. and the supporting part (4) of each end head (35a, 35b) of the back-up roll (3) rests on the said crossbeam (16) via a back-up part (42) delineated by a contact face (41) with a convex rounded profile matching that of the back-up face (63).
