A structural element for a supporting system of photovoltaic modules having a cross section comprising a first part (1 ) U-shaped and symmetric with respect to a symmetry axis (a) so that said first part (1 ) comprises a first seat of gaskets (12 or 12') in each of the stems defining said U. Each seat (12 or 12') is symmetrically arranged with respect to the other and turned towards the outside of said U. Said first part (1 ) being U-shaped so as to define a slide 13 suitable to house the head of an hammer head screw (31 ). Extruded profiles having different shapes and sizes, based on said structural profile, can be assembled together since each profile comprise a recess (128, 127',227,227',228,228') suitable to house perpendicularly a structural profile having sizes less than said recess and compatible with the recess itself. |
