Recycled Steel

Our products use a high degree of steel, the world’s most-recycled material. Given the increased awareness of green construction, steel is the material of choice because of its positive recycled content and recyclability attributes. Steel products also use less energy to manufacture, ship and install than their concrete counterparts.
