The method for the fabrication of lightweight structural members comprises a first step in which a box structure (10) is manufactured of sheet metal consisting of two half-shells (11, 12), a second step in which a cellular web (16) is manufactured on the surface of which a plurality of three-dimensional cells having hills (17) and valleys (18) are formed, and a third step in which the web (16), placed inside the half-shells (11, 12) so as to bring the hills and the valleys into contact with the half-shells (11, 12), is rendered rigidly and permanently integral with the half-shells (11, 12), and the half-shells in turn are rendered integral with each other; provision is also made for a fourth step, in which the space inside the half-shells (11, 12) is filled with a rigid synthetic resin.
