A structural support beam for use in buildings, bridges, mechanical frames and the like to resist bending due to gravitational and external forces comprising a top substantially flat flange disposed in fixed spaced relationship relative to a bottom substantially concave flange by an interconnecting web and a lower stabilizing brace disposed to engage the opposite end portions of the bottom substantially concave flange and the opposite end portions of the interconnecting web to reinforce the interconnection therebetween.

A truss assembly for use in building construction, comprising a first truss and one or more second trusses attached to the first truss to extend transversely to a face of the first truss upon erection of the truss assembly, wherein the or each second truss is hingedly connected to the first truss for swinging movement about a substantially vertical axis between a folded configuration in which the second truss lies adjacent the face of the first truss and an erected configuration in which the second truss extends transversely to said face.

A pinnacle truss has a first linear support member, a second linear support member stacked on the first support member and a third linear support member stacked on the first support member and the second linear support member. The first linear support member, the second linear support member, and the third linear support member form a triangular support structure. The first linear support member has an L-shaped cross section. The second linear support member and the third linear support member each has a C-shaped cross section.

A pre-cut and pre-measured system for building a metal wall frame is disclosed translated directly from architectural plans of the wall assembly. The metal wall frame includes a track member and a stud member, where the stud member contains a pair of dimples located on either end portion. The pair of dimples nests into an associated pair of indent portions located in the track member. The location of the indent portions and dimple portions are determined by an architectural plan, reducing installation time. The stud and track members come pre-cut to length in bundles connected with metal nips, eliminating the need for any shearing or cutting of the metal pieces.

An arch for a metal canopy, including: a right-hand rafter; a left-hand rafter; and an apex brace, wherein each of the right-hand and left-hand rafters includes: an upper rafter beam and a lower rafter beam, the upper and lower rafter beams having an I-beam shape, a plurality of pylons, each of the pylons having upper and lower I-shaped opening adapted to receive therethrough the upper and rafter beams respectively, and at least a portion of the pylons including an opening for receiving the apex brace therethrough, and a plurality of slanted profiles disposed between the every two pylons of the plurality of pylons
