Process for the realization of reinforcing bars for door and window frames

A process for reinforcing door and window frames, comprising:

• providing a reinforcing bar (1) made of a metal material having at least one drillable face (2),
• drilling in said at least one drillable face (2) to obtain at least one fixing hole (5) in said reinforcing bar (1) having at least one characteristic dimension (A) comprised between 2 mm and 5 mm,
• inducing a penetration of at least one riveting portion (6) of a profiled element (4) into said at least one fixing hole (5) for fixing said profiled element (4) to said reinforcing bar (1) without screws or fasteners;
• wherein the at least one riveting portion (6) is made of softened plastic material;
• wherein said process comprises secondary drilling to form at least one detection hole (9) on said reinforcing bar (1);
• wherein:
• said drilling is performed to form a plurality of fixing holes (5) in said reinforcing bar (1);
• said plurality of fixing holes (5) are arranged in each of a plurality fixing assemblies formed along the reinforcing bar (1) in a circular configuration with a diameter (B) between 5 millimeter (mm) and 25 mm;
• said drilling forms the at least one fixing assembly (8);
• and
• said at least one detection hole (9) is made on said at least one drillable face (2) in an intermediate position between two of said plurality fixing assemblies (8).
