A lightweight steel truss combines thin-gauge, cold-formed steel chords and webs in a rigid triangular lattice that carries roof loads with surprising ease. Because it delivers exceptional strength at a fraction of the mass of conventional hot-rolled beams—or even timber—this technology is rapidly becoming the truss … Read more
