Low Relaxation PC Strand

PC Wire
Standard GB/T5223-2003
        The low relaxation process is applied to PC wires to decrease the loss of relaxation, which
represents the stress decrease as a function of time, under an imposed strain of constant
magnitude. Structural calculation takes into consideration this loss; therefore, if relaxation loss is decreased, the
steel section for a given stress is also lesser.
The low relaxation characteristics are conferred to the product through a thermo-mechanical
process that heats the steel wires at a temperature of approximately 400 º C and
simultaneously submits them to a tensile stress such that it creates on the material a plastic
strain of the order of 1%.
Application: PC pipeline, PC Sleeper, Bridge, Inclined Cable,
