COMPOSITE PROFILE FOR DOORS, WINDOW OR FAÇADE ELEMENTS

The invention relates to a composite profile for doors, window or facade elements, having a first metal profile and isolated bridging portions; the first metal profile is conneted with one or more isolated bridging portions; each of the isolated bridging portion has at least one end section; at least one end section of each bridging portion extends into a corresponding groove constructed in the first metal profile, wherein the grooves are constituted by the protrusion and bridging parts, the bridging parts abut against the circumferential direction of the wire, the wire is inserted in the corresponding isolated bridging portions; the metal wire is provided with a segment having smooth surface, corresponding bridging parts bear against the smooth surface sections, so as to be slidable and movably fixing the end segment of the islated bridging portions; the bridging parts form a first attaching surface on the smooth surface of the wire, and the remaining surface of the metal wire on the isolated bridging portions form a second attaching surface; by assembing these components, the relation of pressures p on unit area on the attaching surfaces A1 and A2 is pA1>=pA2.
