Metal suspended ceiling panels are a visually attractive and functional type of ceiling covering often used in modern architectural designs. These types of panels can be made from several different materials, but metals such as aluminum, steel, galvanized steel or copper are typically used. Metal suspended ceiling panels can be produced in a variety of sizes, shapes and surface treatment options. Smooth, patterned or perforated surfaces can be designed to suit acoustic performance or lighting requirements.
