Abstract: A light weight metal building truss preferably constructed of 20 gauge steel wherein there are a pair of top chord members and a bottom chord member. The top chord members and bottom chord members are united together at their respective ends forming a triangle. Extending between the top and bottom chord members are supports which are united therewith.The top chord sections in cross section are generally hat shaped being an inverted U with flanges projected from the end of each leg of the U to effect stability of the completed truss.

Abstract: The present invention comprises a portable wall structure including a metal cap forming the top of a wall structure, a metal floor track forming the bottom of the wall structure, and a series of channeled load-bearing studs that are secured vertically between the cap member and the floor track member. These vertical studs are composed of steel of about 20 gauge thickness. A vertical steel stud is positioned at each end of the wall structure to provide closed ends of the wall structure. This wall structure forms a separate unit of substantially rectangular configuration which may be prefabricated and separately transported to a building construction site. Some parts, such as top plates, corners, door surrounds, and window surrounds, made of wood, are included in some embodiments of the invention.

Abstract: The present invention comprises a portable wall structure for use on the top floor of a multiple story building. The wall structure includes a metal cap forming the top of a wall structure, a metal floor track forming the bottom of the wall structure, and a series of channeled load-bearing studs that are secured vertically between the cap member and the floor track member. These vertical studs are composed of steel of about 26 gauge thickness. This wall structure forms a separate unit which may be prefabricated and separately transported to a building construction site for use on the top floor of a multiple story building. Some parts, such as top plates, corners, door surrounds, and window surrounds, made of wood, are included in some embodiments of the invention.

Abstract: A prefabricated sheet metal wall module comprises: an upper horizontal cap member of inverted U-shaped cross-sectional configuration with a pair of parallel longitudinal dependent side flanges; a lower horizontal floor track member of U-shaped cross-sectional configuration with a pair of parallel upwardly extending longitudinal side flanges; and a series of parallel upright studs each having a pair of opposite longitudinal side flanges. The upper and lower ends of each stud telescope into the upper and lower horizontal members respectively with the side flanges of the stud in intimate surface contact with the side flanges of the horizontal members thereby providing four rectangular areas of two layers of metal.
