In combination, extruded aluminum trim strips joined end-to-end and a splice plate, the trim strips together, the trim strip cross-sections including a web and a pair of opposed angles, the angles and web forming a track for receiving a mid-section of the splice plate with a close sliding fit, the splice plate having lever tabs at opposite ends, notches at sides of the plate, the plate being disposed in the tracks of both lengths of trim strips, the lever tabs and associated edges of the lever tabs formed by the notches being outside of the tracks, the associated edge being arranged in a locking manner with outer surfaces of the angles as a result of the lever tabs being bent in place towards the web.

A slat ceiling apparatus includes a frame and a plurality of slats spanning the frame. The frame includes first and second frame members, each having an inner side and an outer side. A plurality of slots are defined in the inner side of each frame member. Each slat includes first and second longitudinal ends. The first longitudinal end is positioned in a slot on the first frame member, and the second longitudinal end is positioned in a slot on the second frame member. A plurality of slats are arranged spanning the first and second frame members, each having longitudinal ends received in corresponding slots on the first and second frame members. The slats are arranged in a substantially parallel orientation in some embodiments, and a gap is provided between each slat.

A ceiling system including: a ceiling structure suspended in an interior space. The ceiling structure includes: a perimeter frame defining a central opening, the perimeter frame comprising a fabric gripping member; a support grid comprising a plurality of intersecting struts defining a plurality of grid openings, the support grid disposed within the central opening and coupled to the perimeter frame; a plurality of acoustic ceiling panels, each of the acoustic ceiling panels mounted to the support grid and disposed in one of the grid openings; and a tensioned fabric sheet having a perimeter portion that is engaged by the fabric gripping member of the perimeter frame, the tensioned fabric sheet located below the acoustic ceiling panels and covering the central opening.

A ceiling system is disclosed in which two type of ceiling panels are mounted in a support grid. In one embodiment, the ceiling system may comprise: a support grid defining a plurality of grid openings; a plurality of grid-concealment ceiling panels mounted to the support grid and disposed in the grid openings, each of the grid-concealment ceiling panels comprising peripheral edge portions which extend beneath and at least partially conceal the support grid; and one or more tegular ceiling panels mounted to the support grid and disposed within the grid openings, wherein the one or more tegular ceiling panels do not extend beneath the support grid.

A metal panel configured to be supported in a suspension ceiling grid is provided comprising a metal sheet with a central planar portion and upturned edges defining a plurality of sides of the panel. The upturned edges comprise a first, generally-upwardly extending portion sharing a common edge with the central planar portion, a second, generally horizontally portion extending inwardly from and sharing a common edge with the first portion, and a third, generally downwardly extending portion sharing a common edge with the second portion, the first, second and third portions of the edges defining downwardly-opening channels. At least one cross brace is provided that extends between at least two sides of the panel, the cross brace having ends configured to be received in the channels. The central planar portion of the panel is secured to the cross brace to limit deflection of the central portion.
