Suspended ceiling tees are horizontal framing elements that create a framework for holding ceiling panels in place. They are typically made from metal, such as galvanized steel or aluminum, and come in varying sizes and configurations. The name “tee” refers to the shape of the profiles that make up the grid system, resembling the letter “T.” These tees work in conjunction with vertical hangers, which suspend the grid from the structural ceiling, creating an air space above that can accommodate various systems.
