    摘要： Sag in ceiling tiles is reduced by the present coated ceiling tile and method which decreases sag in the coated ceiling tiles. Calcined gypsum and water are combined to form a coating which is applied to the back side of a base ceiling tile in a thin layer of about 100 micrometer to about 1000 micrometers. The coating optionally includes a set time modifier. This method makes a coated ceiling tile from a base ceiling tile having a front side and a back side opposing the front side. The coating is applied to the back side of the base ceiling tile, the coating comprising an interlocking matrix of calcium sulfate dihydrate. Optionally, remnants of the set time modifier are present within interstices in the gypsum matrix. The remnants of the set time molecule include ions, molecules, particles or combinations thereof.

    摘要： Suspended ceiling grid runners include a flange extending laterally to both sides, the flange forming a three dimensional face including sides visible from below a plane of the grid, opposed cross runners intersecting through runners with their ends joined by mutually interlocking end connectors extending through a slot in the through runner, the cross runner ends including end edges configured to abut a respective side of the flange of the through runner, a connector when connected to an opposite connector causes the associated end edges to resiliently locally deflect the abutted flange side to substantially eliminate any gap therebetween.

    摘要： An elongated grid runner, and its manufacture, comprising a pair of overlying metal strips roll-formed together into a shape suitable for use in a rectangular grid to support ceiling panels, one of said strips serving as a visible cap for concealing the other strip forming the main body of the grid runner when the grid member is employed in a completed ceiling, the strips being lanced at each end of the grid runner to lock the cap strip on the main body strip whereby when the overlying strips are simultaneously cut to a finish length prior to finish roll-forming, the ends of the strip are maintained in substantially overlying end-to-end registration where the cap is visible in a finished ceiling.
