Door/window frame structure and the method for making such a door/window frame structure

Door/window frame structure for making door/window casing suited to be anchored to a supporting wall, said structure comprising:

• at least one metal end element (2) suited to define the outer surface (3) of the door/window frame;
• a substantially straight insulating element (4) suited to promote thermal insulation between the environments located, respectively, inside and outside with respect to the door/window frame structure;
• at least one pair of straight metal profiles (13) having a first end (16) suited to be directly coupled with said insulating element (4);
• at least one profile (13) of said at least one pair having a second end (19) suited to be directly anchored to said metal end element (2),
• characterized in that each profile (13) of said pair is internally hollow and has a closed cross-sectional shape.
