Abstract
A method is provided for adding strength to a T-bar grid fabricated with a double web and capped system. The addition of strength is achieved by coating the inside portions of the T-bar with a hot melt adhesive. Cooling sets the adhesive and results in the parts of the grid member becoming a unitized structure.
