This lightweight steel truss study was carried out on a full scale with a span of 6 m and a slope of 300, while the loading test pattern at the placement points of battens was like truss in the community. The goals of this study to measure and observe several parameters including weight, maximum capacity, stiffness, ductility, price, length of work, and failure pattern.
