PC Strand is made
of 7 cold-drawn high carbon wire rods with six outer wires and one single wire which is slightly larger in diameter. The wires are spun together in the same direction and with the same laying length which is subjected to final thermo-mechanical treatment (annealing). The final output of the process is an unadjustable strand in the master coil of 20 – 27 net tonnes which is then wound into smaller diameter coils. It is typically used in pre-stressed concrete girders, bonded post-tensioned flooring system, hollow-core slabs, as well as ground and rock anchors.

Conforming with EN 15804:2012+A2:2019 and PCR 2019:14 v1.11 Construction Products, the EPD for PC Strand covers Cradle-to-gate (A1-A3) with options (A4: transport to customer), plus modules C1–C4 and module D.). Additional impact category results are also presented to support comparability across EPDs based on other PCRs aligned with version 3.01 of the GPI and comparability across EPDs conforming to EN 15804:2012+A1:2013.
