A supporting frame (1) for sectional doors is described, comprising a jamb (5) vertically attached to a wall sidewards the door, a first track (10) and preferably a second track (20) both constrained to the jamb (5); the first track (10) comprises a first profile (11) vertically extending from a lower end (5a) of the jamb and defining a horizontal length (10a), and a second profile (12) defining a curvilinear length (10b) and a horizontal length (10c) of the track (10). If present, the second track (20) is attached to the jamb (5) above the first track and it comprises a third profile (21) defining an oblique length (20a) and a horizontal length (20b). Each of the two tracks implements a continuous path guiding the sliding rollers of the door panels (3). Furthermore, the first, second and third profiles are made each in one-piece. The jamb (5) comprises a first (6) and a second (7) threaded holes, and the first track comprises a first screw (15) which can be inserted in the first threaded hole for attaching the first track to the jamb and the second track comprises a second screw (25) which can be inserted in the second threaded hole for attaching the second track to the jamb. |
