Method of producing spacing elements for concrete reinforcements and/or concrete structures, comprising: (a) providing at least six parallel longitudinal rods in a plane, comprising - two peripheral longitudinal rods; - at least one punching slot consisting of a pair of longitudinal rods situated next to each other (3, 4 and 5, 6); - a central longitudinal rod between each peripheral longitudinal rod and the adjacent punching slot; - if the longitudinal rods form two or more punching slots, a central longitudinal rod situated between each pair of adjacent punching slots; and - optionally, one or more additional longitudinal rods situated between the peripheral longitudinal rods and outside the punching slots; (b) placing transverse rods perpendicular to the longitudinal rods (2, 3, 4, 5, 6) on top of and/or under the latter, and fastening the transverse rods to the longitudinal rods (2, 3, 4, 5, 6), thus producing a lattice structure; (c) cutting transverse rods overhanging the peripheral longitudinal rods at an angle according to a plane angled to the longitudinal axis of the transverse rods such that one or more transverse rods have oblique ends; (d) punching out or cutting through the transverse rod portions between the adjacent longitudinal rods (3, 4 and 5, 6) of the punching slot, thus producing two or more elongate lattices (a, b, c), each comprising three parallel longitudinal rods which are connected to each other by transverse rods which run perpendicular and are laterally connected to the longitudinal rods; the transverse rods not projecting or at most projecting 0.5 mm beyond the bottom longitudinal rods (2, 3); and (e) bending the two or more elongate lattices (a, b, c), thus producing two or more spacing elements, each comprising three parallel straight longitudinal rods including two bottom longitudinal rods (2, 3) and a top longitudinal rod, connected to each other by U-shaped transverse rods which run perpendicular and are laterally connected to the longitudinal rods; the transverse rods not projecting or at most projecting 0.5 mm beyond the bottom longitudinal rods (2, 3).
