Spatial reticular Beams in hot galvanized steel or in AISI 304 stainless steel with a system of linkage according to the patent number 0001334730. Its mesh is composed by tightened poles that are previously compressed in tubular section hollow sectional steel. The pole extremity is made by PRESSOSCHIACCIATURA, converging on superimposed sheets hearts and linked among them by bolting. The fabrication allows an excellent level of standardization being the structure totally prefabricated: all this offers notable assets for the storage and the transport. The assembling occurs normally in spot, in parts or in aggregate and the construction is subsequently positioned in altitude with a crane. With the Profilspace system is possible to achieve great windows on two supports. Profilspace offers the ideal solution for great buildings where an excellent architectural appearance is required just like airports, stadiums coverings, gyms and hangars.
