The UNI4 structure, which consists entirely of galvanized steel, has an innovative 4-branch head to which the stringers can be attached. This support is used both in stringerless and stringered versions. There are different configurations available depending on the different load conditions: Light or Medium with an open section and Heavy and H with a closed section. The upper surface of the structure is covered with plastic gaskets in order to improve sound absorbtion and make it airtight.
The advantages of the UNI4 model are: its compact structure, the speed and ease of installation, the wide height adjustment range which allows a large range of adaptation in the height of the floor slab, the “snap-on” system (present in the L and M stringer versions) which enables a particular conformation at the edges resulting in simple and correct assembly and the locking of the stringers before the final screwing.
