Abstract
The present invention provides for a metal stud for use in sound attenuating wall systems utilizing high density, abuse resistant wallboard, the metal stud having specific steel chemical and mechanical properties to result in increased sound attenuation properties while maintaining the load carrying capacity and screw performance providing improved economics. The metal stud is a generally C shaped metal stud constructed of 0.0180 steel having at least 57 ksi strength having two parallel spaced apart flanges joined along the length of one edge by a central web and being provided with an in-turned double thickness hemmed ledge along the length of the second edge, the flanges having a width of greater than 1⅜ inches between the one edge and the second edge, each of the flanges being provided with a reinforcing rib centrally located in the flange extending the length of the flange. The central web has a main central section bordered by channel shaped ribs extending longitudinally of the stud outwardly of the central web, the edges connected to the edges of the flange.
