Low relaxation process

Consisting of a thermo mechanical technique in which the PC strand is tempered at a temperature of 300 – 400 ºC, whilst subjected to a tensile force so that the material undergoes a plastic deformation of 1%. By means of this process the residual stresses of the material produced by wire drawing and cabling are eliminated.
