EXPANDED METAL PRODUCTS ABSTRACT OF THE DISCLOSURE A novel and improved, expanded metal is dis- closed along with novel and improved products incorporat- ing such expanded metal. The expanded metal is formed from a piece of sheet metal which is lanced in nested arrays so that when the metal is expanded, diagonal legs are connected to the remaining portion of the sheet metal by folds. After the expanding operation, the legs are substantially coplanar with the adjacent portions of the piece of sheet metal, and the only material deformation of the metal occurs along the folds. The illustrated legs and adjacent projections, which are connected to the legs by folds, are curved so that the centers of the legs have a maximum width. The expanded metal is illustrated incorporated into various types of framing members used to position interior panels of building structures, such as drywall studs, floor tracks for drywall construction, and intersection tracks. Also disclosed are grid tees for suspension ceilings and wall molding members for sus- pension ceilings.
