The FSTFZ fixing system is used to secure reinforced concrete ceilings and false ceilings. This type of work, done on all types of buildings in need of renovation, is very important in securing public buildings such as schools, cafeterias and hospitals. The system is made up of a Ø 68 mm disk with a cap, a 4 sector anchor in PA6 Nylon, and a Phillips flathead galvanized steel screw. In order to secure the structure, the system allows for the fixing of reinforced material meshes to the ceiling, which can then be finished with a plaster or appropriate resin grout or left naked. The disk’s closing cap allows for complete insolation in order to avoid thermic bridges and, in the case of visible structures, a pleasant design.
