A structural section for use in frame construction where the section includes a horizontal segment and a pair of spaced apart legs. Each leg has a first end portion attached to the horizontal segment, a second end portion opposite the horizontal segment, and a flange that extends inward from the second end portion toward the centerline of the structural section. Each leg further includes a longitudinal surface located between the first end portion and the second end portion. The longitudinal surface is positioned inboard of the flange so that the distance between opposed flanges that extend along each leg of the structural section is greater than the distance between opposed longitudinal surfaces that extend along each leg of the structural section.

Structural shape for use in frame construction

The invention is directed to a lightweight steel frame system having end nailed connections where lightweight steel structural members frame into support members. The end nailed connection is made by driving fasteners through the support member and directly into the connection end of a lightweight steel structural member without the need for using additional connection hardware. Where the lightweight steel structural member is a roof or floor truss, the support member may include a leveling member to facilitate positioning each roof truss at an elevation set point to produce a level roofline along the finished structure.
