Drywall grid systems by Armstrong World Ind.
November 1, 2004
The company's Drywall Grid Systems offer numerous cost and performance benefits compared to traditional framing and installation methods. The systems are suspended from above using hanger wires, thereby eliminating the cost of material and labor to frame down with stud and track. The systems' main beams and cross tees feature a wide 11⁄2-inch knurled face with a reverse hem that allows easier installation of screw-applied gypsum wallboard by reducing screw skate. They are also rotary stitched, which provides additional torsional strength and stability by reducing twisting of the components when the screws are attached.
