Low relaxation presstressing steel strands are produced using high carbon wire rod.
The production steps include descaling (remove of oxides and surface preparation), wire drawing and stranding followed by a thermomechanical treatment. Those processes are the basis to achieve the desired mechanical properties in order to fulfill the requirements of standards or customer specifications.
