suspended ceiling

A suspended ceiling is a secondary ceiling that hangs below the main structural ceiling. It is typically constructed using a lightweight metal grid system suspended by wires or rods from the floor or roof structure above. This grid supports materials like plasterboard sheets or acoustical tiles.12

Suspended ceilings serve multiple purposes, primarily to conceal the mechanical and electrical equipment that runs between the main ceiling and the suspended one. This can include items such as electrical conduits, air-conditioning ducts, water pipes, sewage lines, and lighting fixtures. This design allows for easier access to this equipment for maintenance and upgrades, while also providing a clean and finished overhead surface for a room.2
