E04C5/00—Reinforcing elements, e.g. for concrete; Auxiliary elements therefor
E04C5/01—Reinforcing elements of metal, e.g. with non-structural coatings
E04C5/06—Reinforcing elements of metal, e.g. with non-structural coatings of high bending resistance, i.e. of essentially three-dimensional [3D] extent, e.g. lattice girders
E04C5/0627—Three-dimensional reinforcements composed of a prefabricated reinforcing mat combined with reinforcing elements protruding out of the plane of the mat
