The system consists of parallel supporting bars (1) and cross-members running in two perpendicular directions and incorporates a hollow extrusion or rail which is open at the bottom and has at least one lip seal (7) on its inner surface running parallel to its lower edge. The supporting bars (1) of the system have channels (9) at the bottom with open lower surfaces and horizontal ribs for supporting suspended components such as lighting. The seal lips (7) are, for example, of PVC, and can be used to seal the upper edge of a partition (c).
