MESH ceiling hooked on concealed carrier with D91s and D91t panels
Entrance halls and wide corridors
PLAFOMETAL-EM-240 is a system with a modern aesthetic appearance. The D91s and D91t expanded metal panels are self-supporting, hooked between concealed carriers, and are suitable for wide corridors where the self-supporting feature of the EM-110 system is not sufficient. Their robustness combined with a wide opening will facilitate maintenance phases throughout the life of the building.
Selection guide
- Acoustic comfort
- Active fire protection
The advantages of the system
- Aesthetic: panels with a modern look featuring hollow joints between panels and the wall.
- Dimension: selection of various panel widths and lengths.
- Opening: demountable with wide plenum access.
- Acoustic: high correction, absorption coefficient αw up to 1 (NRC = 1).
Description
- Wall to wall suspended ceiling composed of expanded metal panels hung on carriers forming a concealed joint
- Self-supporting steel panels
- The panels are equipped with an interior hook-end (BRIC) at one end for suspension on the grid and at the other end with a Z-shaped hook-end (BRZ) resting on the end of the adjacent panel
- The carriers are made of steel
- Optional acoustic enhancements

Expanded mesh
Dimensions
- Mesh: Geometry WL x WD - L x Th
- Panel: width in the WL direction of the mesh, length in the WD direction

Installation
- The direction of light entry through the mesh depends on its laying direction, visually recognizable by its inclination
- Depending on the desired visual effect, panels can be installed in the same direction or alternated every two panels
