Abstract
A suspended three-dimensional ceiling system of improved appearance and performance that includes closely dimensioned main tees and lay-in panels. The main tees have opposed vertical surfaces adapted to abut the edges of the panels to avoid any noticeable non-parallelism between the main tees and/or panels. The vertical surfaces are provided by a protrusion at the juncture between a panel supporting flange and a vertical stem of the main tee. The protrusion allows the panels to be dimensioned to avoid undue interference with a stiffening bulb on the upper part of the stem and provides an attractive reveal on the visible face of the flange.
