The installation of grillo ceilings begins by fixing the supporting frame in the form of a crate, using spring suspensions. Then modules of grilles are inserted into the finished cells. Lighting devices exist in several versions: the size of one or more ceiling cells, or typical spotlights designed to fix in suspended ceilings. It is possible to install and multilevel ceilings of such a system. In these cases, gratings of various configurations are used: pyramidal, pronunciation, asymmetric and standard straight.
