Lattice GirderLattice or Truss Girders are mainly used for the prefabrication of concrete planks, a medular element in the Hallow Block floor Slab System for constructing concrete slabs. Truss Girders have a triangular shape, are electro-welded and have three deformed longitudinal bars (one upper and two lower). They are joined by a smooth diagonal bar in a zig-zag pattern, and are Electo-Welded every 20 cm. |
