Abstract: A roll formed sheet metal grid tee, having a multilayer web, is rigidified by a series of longitudinally spaced tabs lanced through the web. The tabs are cut with a dovetail shape and are foreshortened relative to the holes, made when they are formed, by bending them along a line parallel to a side of the tab that remains uncut. After being foreshortened, the tab is pressed back into its associated hole and tight locking interference is developed between the divergent dovetail sides of the tab and the hole. The tab is incompletely pushed back into the hole so that the layers of the tab are misaligned with corresponding respective layers of the web to assure that the tabs prevent relative shear-like movement and/or spreading of the web layers.

Abstract: A method for securing two pieces of sheet material is provided using a stitch preferably made by sequentially passing the grid member through two die sets. The first die set lances a strap out of the two sheets of metal such that, at the approximate center or midsection of the strap, the first layer of material is displaced completely out of the plane defined by the web, while the second layer is only partially displaced out of the plane of the web so that a portion of the second layer remains in the space vacated by the first layer of the strap. The lanced strap is then passed through a second die set, in which the first and second layers of the strap are deformed or “swaged” such that the first layer is flattened and expanded in width beyond the edges of the hole in the web created when the strap was lanced. This provides interference such that the first layer of the strap cannot pass back through the hole.
