gridded ceiling
Metal grids are fundamental to the structure of a drop ceiling. They are typically composed of lightweight, durable materials such as galvanized steel or aluminum, designed to support the ceiling tiles. The grid system is installed perpendicular to the main beams and consists of two primary components main tees and cross tees. The main tees run the length of the room, while cross tees are used to create a lattice framework that holds the individual ceiling tiles in place.
