Abstract
The present invention relates to ceiling grid runners and associated assembly details that utilize metal reinforcement of thermoplastic compounds in order to obtain the necessary stiffness required to meet load/deflection standards for suspended ceiling systems. The metal is strategically positioned at the areas of highest stress, the top and bottom of the runner cross-section in what is analogous to the bulb and flange of traditional all metal grid.
