Metal profile for door/window frame structure and method for making such profile

A metal profile (1) for door/window frame structures (S, S′), wherein the frame structure comprises a metal frame (A) and/or an insulating element (C) and/or a linear gasket (G) arranged inside said frame (A), said metal profile comprising:

• an elongated body (6) extending along a substantially longitudinal extension direction (L);
• a first end portion (8) of said elongated body (6);
• a second end portion (9) of said elongated body (6);
• wherein said first end portion (8) of said body (6) is suited to interact with the frame (A) and/or with the linear gasket (G) of the door/window frame structure (S, S′);
• wherein said second end portion (9) of said body is suited to be coupled with said insulating element (C) of the door/window frame structure (S, S′) to hold thereof with respect to a substantially transverse direction (T) and form a unitary assembly with said insulating element (C);
• and wherein said metal profile (1) is formed by a piece of bent metal sheet (19) with a pair of end edges (20), said end edges (20) of the piece of sheet metal (19) being reciprocally joined to each other to define a closed and internally hollow elongated body (6).
