ABSTRACT:
A support runner for use in a suspended ceiling system is disclosed with the support runner being useful in ceiling systems having an exposed flange for decorative purposes. The support runner has a decorative trim having a decorative lower surface and an engageable upper surface. An inverted-T runner is supportingly engaged about the engageable upper surface of the decorative trim and extends along the decorative trim a distance sufficiently less than the length of the trim to accomodate heat expansion distortion of the inverted-T runner. When the ceiling system is exposed to heat, the inverted-T runner continues to hold the ceiling panels even though the decorative trim becomes inoperable due to expansion caused by the heat.
