This disclosure relates to a reinforced metal stud for use in a hollow wall. The wall includes sheet metal studs placed horizontally between adjacent, horizontally extending gypsum core boards, typically in the walls surrounding an elevator shaft and stairwells, and in area separation walls and the like. The metal studs include an inner flange, an outer flange and an adjoining web connecting the flanges, with a core board abutting each side of the web. Standard or special fire-retardant gypsum wallboards are attached by fasteners to the outer flanges of the metal studs. A hollow space is thus formed between the core boards and the wallboards, the outer flange and a portion of the web being within the hollow space. A reinforcement channel is provided for attachment to and strengthening of the stud. The web and the outer flange of the stud form a partially enclosed space, and the reinforcement channel nests in the enclosed space. Fasteners secure the channel to the web of the stud, and additional fasteners may secure the wallboard to the outer flange of the stud and to the channel.
