Abstract
A preassembled suspended ceiling grid module comprising a plurality of parallel main tees and a plurality of cross tees, the main and cross tees each having horizontal flanges extended to both sides of a central plane, the cross tees being joined at their ends to the main tees with end connections that enable the module to be folded in a plane corresponding to an eventual ceiling plane in a zigzag pattern, such that the cross tees lie in directions generally parallel to the main tees with the cross tees connected on a side of a particular main tee being folded in a common direction relative to their end connection, and where connected to an adjacent main tee being folded in an opposite direction relative to their end connections with said adjacent tee.
