A direct mount ceiling grid system comprising a plurality of base grid members, cross grid members, and channel grid members for mounting ceiling panels close to a mounting surface. The base grid members are elongated T-shaped beams having a base flange and a transversely extending web having a thicker bulb portion at its marginal end. The base flange of each base grid member is directly mounted to a mounting surface. The channel grid members are elongated beams having two parallel transversely extending webs forming a channel therebetween. Upon installation of ceiling panels, the channel of the channel grid members removably engage the bulb portion of the transversely extending web of the base grid members. The channels have hook portions of the parallel webs of the channel grid members and deflect to allow capture of the bulb portion. The base flange of the base grid members and the base flange of the channel grid members capture the ceiling panels placed therebetween. The ceiling panels are also supported by the base flange of one or more cross grid members.

[What is claimed is:] [1.]a plurality of base grid members each having a T-shaped cross-section formed by a base flange portion and a transversely extending web portion, the transversely extending web portion defining two sides of the web portion and having a relatively thicker bulb portion at its transversely extending marginal end, the bulb portion having a predominantly annular cross-section thereby providing a curved outer surface, the base flange portion directly mounted to the mounting surface such that the web portion depends downwardly;a plurality of channel grid members each having a base flange and two transversely extending parallel webs forming a channel therebetween, each of the webs having a hooked portion bent inwardly and downwardly into the channel along its marginal end, thereby providing a hook edge, the channel removably and frictionally fitted over the bulb portion of the transversely extending web portion of the base grid members whereby the hooked portions of the parallel webs of the channel grid members capture the bulb portion with the hook edges abutted against the curved outer surface of the bulb portion, the base flange portion of the grid members and the base flange portion of the channel members capturing the ceiling panels placed therebetween so that the ceiling panels are positioned in a common plane adjacent to the mounting surface.
