Abstract: An extruded metal construction stud for use within a multitude of different interior room wall systems is disclosed as comprising a substantially U-shaped structure defined by means of a base web and a pair of perpendicular sidewalls. Each of the sidewalls is substantially S-shaped in configuration, and the corresponding parts thereof are reversed such that the sidewalls are, in effect, mirror-images of each other. Each of the sidewalls defines a pair of oppositely facing open channels integrally connected by means of a common flange. One of the channels is open to the exterior of the stud and accommodates edge portions of wall board panels. Flanges of the channels separate from the common flange serve to define support surfaces for wall board panels as do laterally outer portions of the sidewalls. The different wall systems are able to be expeditiously erected by incorporating one or more of the construction studs within the particular wall structure in a variety of different modes.
