(54)	Method and system for making prefabricated structural grid-like panels for making buildings

(57) A system for making prefabricated structural grid-like panels for making buildings provides to use a pair of rollers which can be moved toward one another in order to press therebetween a preformed panel comprising a top net sheet and a bottom net sheet, therebetween an insulating material is arranged. As the net sheets are pressed, cross members of said sheets penetrate the insulating material to project from the opposite side thereof, thereby the cross members can be welded on wires of the corresponding net sheet.
