Abstract: Disclosed is a suspended ceiling having rectilinear panels held within a co-planar matrix of inverted T-grid elements; each T-grid element possesses a horizontal and a vertical component.The T-grid elements are suspended by their vertical component from the natural ceiling or ceiling beams. The improvement set forth relates the use of imitation beams secureable to the horizontal components of the matrix of T-grid elements at a time after installation of the suspended ceiling has occurred. Each of the imitation beams is an elongate rectilinear element complemental on at least one surface with the horizontal component of the T-grid elements. Included are press-fit securement elements in the rectilinear elements, such elements imbedded within the complemental surface of the elongate elements. Thereby an imitation beam structure for a suspended ceiling may be achieved through the manual affixation of the rectilinear elements to the horizontal components of the matrix of the T-grid elements.
