发明名称 Grid tee for suspension ceiling
摘要 In one embodiment, a roll-formed sheet metal tee for grid type suspended ceilings with the face of its flange integral with the stem and the layers of the stem fixed together for improved torsional strength. An upper region of the stem can have one or more of its layers folded to increase suspension wire breakout strength. A stiffening bulb is below suspension wire receiving holes so that a loop of the suspension wire through the tee has a narrow profile and thereby avoids interference with ceiling panels during their installation or removal. Other embodiments of a tee share the feature of a narrow, suspension wire receiving upper stem portion.
