Gypsum grid ceilings, also known as suspended or drop ceilings, consist of a framework (the grid) made from metal or other materials that supports gypsum panels. These ceilings are installed below the main structural ceiling, creating a space that can accommodate electrical wiring, plumbing, and HVAC systems. Their smooth finish and adaptability make them a popular choice for various settings, including offices, shopping malls, hospitals, and residences.
