A grid tee for suspension ceilings is disclosed which includes a metal strip bent to provide a stiffening bulb along one edge, a pair of parallel web portions extending from the bulb in face-to-face adjacency, and a flange portion extending laterally in opposite directions from the side of the web remote from the bulb. A second elongated piece of sheet metal forming a cap is positioned against the side of the flange remote from the bulb and is connected to the flange along the edges thereof by a reverse bend. A band of cross-link cured adhesive is located at the interface between the flange and the cap, bonding the two together. The adhesive effectively closes the section and provides torsional stiffness to the grid tee.
