This general con struction is well known in the art and it is believed that further description is unnecessary. In the usual studs of this type, the aligned flanges present only a flat surface to the wall boards, and the boards are secured snugly against this flat surface by means of the nails driven into the studs. In the present invention the out standing flanges 3 are provided at spaced inter vals throughout the length of the stud with out wardly extending projections I0. The projec tions are spaced along the edge of the flanges a - 4 jections I6 are slightly rounded to provide a somewhat wider bearing surface, which may be preferable when soft wallboards are used, while the projection |'| shown in‘Fig. 5 provides more nearly a line contact, which may be preferable for some types of boards. , Figs. 6, 7, and 8 illustrate a wall structure in cluding a corner stud I8. This stud may aptly be called a Y-beam and is preferably formed of a wide web member I9 having a laterally extend ing web 20 welded thereto as at 2|. This pro vides a Y-beam in which the arms of the Y are the outwardly extending web portions 22 and 2l at an angle to each other corresponding to the applied tothe face of the stud will contact with 15 angle of the corner, the apex of the angle being intersected by an inwardly extending web por a plurality of the projections and the boards will tion 24 which forms the leg of the Y-beam.

Another important advantage is that a materially 35 of the angular flanges 3| throughout the extent of the boards and an air space 33 will be provided less amount of metal is required in the manufac between the body of the stud and the boards and ture of the studs.
