(57) The invention relates to a system for the building of wide span roofings, in which it is foreseen the use of a frame made of shaped sheet purlins (3) which are placed on the frame structure (1) of a building at different distances, depending on the span and on the weight. It is also made of covering (2) and ceiling panels (15), that can be made of insulating panels or the like fastened to said purlins.
According to an embodiment of the invention, these covering and ceiling panels have their stiffening ribs right-angled with respect to the purlins.
