ABSTRACT:
A metal truss structure which is characterized by chord and web members formed of rectangular tubing and with the chords of double construction to take advantage of the weight and cost savings and high torsional strength of rectangular tubing and arranged for easy and inexpensive fabrication by avoiding precise cutting and difficult welding requirement. This metal truss structure comprises chords, each including a pair of laterally spaced-apart rectangular tubing members positioned flat against opposite sides of the rectangular tubing web members at one corresponding end and welded exclusively by weld lines extending along the longitudinal intersections of the chord members with the web members for simple and automatic welding.
