  • Figures 1a) and 1b) show two examples of a lattice structure 4 consisting of longitudinal bars 2 and transverse bars 3. These are special mats, which are used, for example, for precast concrete elements.
  • the geometry of the welded wire mesh can vary greatly and must correspond to the geometry and the static requirements of the concrete element in which the welded wire mesh is used.
  • the lattice structure 4 shown in FIG. 1 a) has a door opening 37, window 38 and sloping roof 39.
  • the lattice structure 4 shown in FIG. 1 b) has openings 40 and bevels 41.
