A high-strength grid member is provided that comprises two standard Tee-shaped grid members that are vertically aligned to form an I-beam configuration with the strengthening bulbs of each being spaced apart. A plurality of clips is secured to the spaced-apart bulbs by means of fasteners to secure the two grid members together.

High strength grid member for suspended ceilings

A suspended ceiling system is described composed of a grid of tees, ceiling tiles supported on the tees, a perimeter molding supporting the tees and the tiles adjacent a wall to which the wall molding is secured. The perimeter molding has an elongated, longitudinally-extending metal body with a first vertical leg configured to be secured to a wall. A first horizontal leg extends from the lower end of the first vertical leg. A second vertical leg extends from the first horizontal leg and a second horizontal leg extends from the upper end of the second vertical leg toward the first vertical leg. The second horizontal leg includes a free end spaced from the first vertical leg.

Suspended ceiling system including perimeter molding

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.
