This suspended ceiling system not only can realize sound absorption, noise reduction, ventilation and other functions through the hole rate, hole diameter and arrangement mode, but also can meet the individualized needs of modern large public buildings and commercial complexes for space rhythm and light performance.

In the embodiment, the transverse keel 2 is a light steel keel made of hot-dip galvanized rectangular steel pipe.

[0026] The suspended ceiling connector 4 is arranged below the transverse keel 2, and the upper end thereof is fixedly connected with the transverse keel 2. A plurality of suspended ceiling connectors 4 are arranged at intervals along the length direction of the transverse keel 2. The distance between two adjacent suspended ceiling connectors 4 on the transverse keel 2 should be set according to the size of the perforated aluminum plate 3, so that the two adjacent suspended ceiling connectors 4 are connected with the same perforated aluminum plate 3 and serve as the load-bearing member of the perforated aluminum plate 3. The suspended ceiling connector 4 is a structure with adjustable length in the vertical direction, which provides adjustment of the size of the suspended ceiling connector 4 during installation, so as to install perforated aluminum plates 3 with different heights or angles.
