LGS History
Why LGS?


  • High ‘strength-to-weight ratio’ (individual members are lighter per unit length than traditional wood, steel or concrete framing members).
  • 100% recyclable (can be continuously recycled without losing physical properties).
  • Inorganic (will not rot, warp, split or crack).
  • Inert (does not emit fumes, gases, vapor or support the growth of molds & fungi).
  • Dimensionally stable (does not expand or contract with moisture content).
  • Produced in strict accordance with national standards (no variation in quality).
  • Non-combustible (does not contribute fuel to a fire, not susceptible to fire.).
  • Structures can be designed to meet any degree of loading (e.g. high seismic or high wind loads).
