Abstract (en)

[origin: WO2022152697A1] The invention proceeds from a steel wire mesh (54a-d), in particular a hexagonal mesh, made of steel wires (10a-d, 12a-d, 14a-d) having hexagonal loops (16a-d), in particular for use in the construction sector, preferably for use in the field of protection from natural hazards, wherein the steel wires (10a-d, 12a-d, 14a-d) are alternately twisted with adjacent steel wires (10a-d, 12a-d, 14a-d), and wherein the steel wires (10a-d, 12a-d, 14a-d) are made of a high-strength steel or at least have a wire core made of high-strength steel. According to the invention, a ratio, in particular an average ratio, of a loop width (18a-d), in particular an average loop width, of the hexagonal loops (16a-d), to a loop height (20a-d), in particular an average loop height, measured perpendicular to the loop width (18a-d), of the hexagonal loops (16a-d), is at least 0.75, preferably at least 0.8. The invention also relates to a production device and to a production method.
