Eventually the reel is cut into individual tendons (refer to http://www.youtube.com/watch?v=iq_ZZV… ).

This process is for Unbonded Post-Tensioning System used in Concrete Construction.

The steel strand is moving at over 200 feet per minute in the extrusion machine. First the steel PC strand is coated with corrosion-inhibiting Post-Tension Coating (“grease”). Then, the coated steel has either 40ml or 50ml of HDPE (high-density-polyethylene) plastic extruded over it. Finally, the extruded strand is cooled within a long trough of chilled water.
