Claim:
A preassembled suspended ceiling grid module comprising a plurality of parallel main tees and a plurality of cross tees, the main tees having a nominal length that exceeds twice the nominal length of the 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 each of 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 a plurality of the cross tees connected on a side of a particular main tee being folded in a common direction relative to their end connections, and where connected to an adjacent main tee said plurality of cross tees being folded in an opposite direction relative to their end connections with said adjacent tee.
