Abstract: A light steel structural member includes a web portion and a pair of flanges. The web portion has a web face. The pair of flange portions each extend generally orthogonally from each end of the web portion. The flange portions each having a plane and the planes are generally parallel each other and each flange has a flange face. At least one of the web face and the flange face has a plurality of embosses formed therein. In another embodiment the light steel structural member further includes a pair of restraining ribs. In a further embodiment the light steel structural member further includes a pair of lips and a pair of multi-cranked stiffeners. A method of making the light steel structural members is shown.

Abstract: A wall panel includes an outer surface layer, an oriented strand board layer, and mounting channels. The outer surface layer includes an outer surface, an inner surface, and edges. The oriented strand board layer includes an outer surface, an inner surface, and edges, with the outer surface of the oriented strand board layer being attached to the inner surface of the outer surface layer. The mounting channels are defined along and between the edges of the outer surface layer and the oriented strand board layer, and define a region recessed from the edges of the outer surface layer and the oriented strand board layer.

Abstract: A portable, rapidly erected fabric covered building-type structure has a plurality of articulated arch frames which may be hoisted from the ground to extend transversely in longitudinally spaced vertical planes. Spreaders rigidly connect the arch frames. Individual rectangular fabric sections extend transversely between corresponding adjacent pairs of the arch frames to provide an interior sheltered from the outside environment. The side edges of the fabric sections are connected to the rails of removable ladder-like mechanisms carried by the frames for tensioning the sections across their widths. The ends of the fabric sections are also pulled downwardly at the sides of the building by other mechanisms for tensioning the fabric sections lengthwise.
