ABSTRACT:
A structural metallic member particularly useful for framing interior and exterior walls, ceilings and floors of building structures consists of a hollow generally quadrangular in transverse cross-section stud consisting of at least three contiguous walls with the middle of the at least three walls being provided with a multiplicity of parallel, spaced, longitudinal rows of longitudinally spaced slits with alternate rows of slits being staggered such that the longitudinal spaces of one row are positioned substantially midway of the length of the slits of adjacent rows. In a form of studs where there are four contiguous walls, the slits are provided in the pair of opposed walls that will connect the inside and outside walls of the structure.
