A suspended three-dimensional ceiling system 10 of improved appearance and performance that includes closely dimensioned main tees 11 and lay-in panels 14. The main tees 11 have opposed vertical surfaces adapted to abut the edges of the panels 14 to avoid any noticeable non-parallelism between the main tees and/or panels. The vertical surfaces are provided by a protrusion 28 at the juncture between a panel supporting flange 21 and a vertical stem 22 of the main tee. The protrusion allows the panels to be dimensioned to avoid undue interference with a stiffening bulb 26 on the upper part of the stem 22 and provides an attractive reveal 33 on the visible face of the flange 21. |
