E04C5/00—Reinforcing elements, e.g. for concrete; Auxiliary elements therefor
E04C5/01—Reinforcing elements of metal, e.g. with non-structural coatings
E04C5/02—Reinforcing elements of metal, e.g. with non-structural coatings of low bending resistance, i.e. of essentially one-dimensional [1D] or two-dimensional [2D] extent
E04C5/03—Reinforcing elements of metal, e.g. with non-structural coatings of low bending resistance, i.e. of essentially one-dimensional [1D] or two-dimensional [2D] extent with indentations, projections, ribs, or the like, for augmenting the adherence to the concrete
