Prestressed Material

Cordon De Acero De 2 y 3 Hilos

Cordon De Acero De 2 y 3 Hilos is Stress relieved two and three-wire strands, these are strands of drawn wire, consisting of 2 or 3 wires of the same diameter, coiled helically and with uniform pitch, around their longitudinal axis. their longitudinal axis. It is mainly used for the manufacture of joists and hollow core slabs.

Stress relieving process  is a thermal process in which the steel strands,  after braid forming, are heated to a temperature of 360 - 400°C to remove a temperature of 360 - 400ºC to remove the residual stresses in the residual stresses in the material that were obtained in the drawing and stranding.

We produce Cordon De Acero De 2 y 3 Hilos strictly in accordance with IRAM–IAS  U500–07
