Abstract: A building truss that is light weight, and easily manipulated yet provides superior strength for support is disclosed. The building truss is defined by a pair of parallel and spaced apart square tubing members, having joined between them, a lattice of cold rolled round reinforcing rod having a sinusoidal or zig-zag pattern. Additional spacers are provided to prevent twisting. Also, angled reinforcing pieces may be attached to the lattice for increased load bearing capabilities.
