Abstract
Filiform element usable for reinforcing moldable materials particularly concrete, said filiform element having crimpings or corrugations distributed over its length, showing the following features: maximum wave amplitude of the longitudinal axis: 1 to 1.5 d; maximum wave-length: 10 d; minimum wave-length: 7 d; maximum fiber length: 65 d; minimum fiber length: 45 d; fiber diameter (d): max. 1.2 mm; nature of the steel: ultimate tensile strength higher than 110 kg/mm.sup.2 and lower than 150 kg/mm.sup.2.
