Abstract
A light gauge metal truss system including trusses contructed of roll formed truss chord and truss web members and a two piece roll formed truss anchor for anchoring the truss to a wall. The truss chord members are roll formed to have a generally U-shaped cross-section with a base and two substantially parallel legs with reinforcement ribs and inwardly turned hems to improve structural capacity thus improving the strength-to-weight ratio of the chord member and minimizing costs. The truss web members are roll formed to have an H-shaped cross-section with the internal flange offset from the center of the legs to provide an enlarged attachment surface. The web member also includes reverse folds and hems to improve structural capacity thus improving the strength-to-weight ratio of the web members and minimizing costs.
