Modular system for building furniture using aluminium profiles

A modular system of furniture construction from aluminum profiles, comprised of a set of extruded aluminum profiles (1) which each are rectangular in shape and combine to make up the walls, the base and the ceiling to form the structure of the furniture, characterized in that each profile ends (2) includes double hitch finishes (3) that allow linking and fixing each other varying the dimension of the bottom of the furniture, the double hitch finishes form a double coupling, at one end (2), in the continuation of the lateral faces of the profile (8), one lateral face is about 12 millimeters longer than the other lateral face, and both finished in loops facing inwards (9), and comprising the other end (2) where it also couples an extension of their faces, about 12 millimeters one more than the other, and both finished in loops facing outwards (10), the loops that are facing outward are slightly narrower than the width of the profile, so that they are aligned internally with the loops of the hitch to be coupled, due to a double angle of 45 degrees (11) just before reaching these loops that look out (10).
