A suspended ceiling grid beam is provided that has an increased beam height to provide enhanced resistance to downward deflection. The beam has a cross-section generally in the form of an inverted T, with a central web, a pair of panel support flanges extending from one edge of the web, and a reinforcing bulb extending from the other edge of the web. The reinforcing bulb has a generally planar, fin-like structure extending therefrom opposite to and generally co-planar with the central web.
