Swing-down MESH ceiling on concealed profiles with D92s and D92t panels
Office and hospital corridors
PLAFOMETAL-EM-110 is a system adjustable to the dimensions of corridors. The D92s and D92t expanded metal panels are self-supporting from wall to wall, avoiding the need for suspended grids in crowded plenums with numerous distribution networks. They create an elegant reveal joint with the wall. Their durability, combined with a wide opening by tilting on both sides, will facilitate maintenance phases throughout the building's lifespan.
Selection guide
- Acoustic comfort
- Active fire protection
The advantages of the system
- Aesthetics: panels on concealed framework with offset edge featuring a hollow joint to absorb alignment deviations with the wall for a straight finish
- Opening: swing-down from below, ideal for crowded plenums, and robust in handling
- Plenum ventilation: suitable for hospital environments
- Acoustic: high correction, absorption coefficient αw up to 1 (NRC = 1)
Description
- Self-supporting ceiling made of expanded metal panels hung on a concealed profile creating a closed gap joint between the panel ends and the wall
- Self-supporting steel panels with seamless edges
- The panels have raised inner hook ends (BRIC) allowing them to be suspended on the framework and tipped. This provides the panel with robustness for handling
- The edge profile consists of a reprise ledge to be fixed to the wall and a hooking profile to be offset and fixed under the wing of the ledge according to the length of the panels between notches. It allows the closed gap joint thus formed to absorb alignment deviations with the wall
- Optional acoustic enhancements
Bulk cut
A gap A is required between the panel and the wall. Dimensions in mm.
Appearance

Expanded mesh
Dimensions
- Mesh: Geometry WL x WD - LG 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, the panels can be installed in the same direction or alternating every two.
