A process for the fitting of sections, particularly sections for metal carpentry, intended for the building of frames, the section being cut at 45 DEG , comprising the steps of executing on the sections a local recessing of the cage in order to provide the sections with at least one notch and a corresponding number of oriented straps, inserting into each of the sections to be put together a fitting-element of an almost trapezoidal shape provided with at least one snug on the opposite side to the one provided with tenons and slots, the at least one snug serving the purpose of lateral guiding, this same element being also provided with a drilling perpendicular to the miter of the section cut at 45 DEG , drilling to be found on the tenons and slots side and in the longitudinal axis of the section; bringing the at least one snug of the fitting element to the at least one corresponding notch provided on the section, at least one strap serving as guide for the purpose; fitting the sections together by joining the miters, and fitting the tenons and slots of the fitting element already inserted into the cage of a first section, into the slots and tenons of a similar fitting element previously placed in the cage of another section; introducing a tightening part into the drilling made on the two fitting elements, which in this manner prolong each other, and tightening the part into situ.
