Parallel Wire Strands (PWS)

Shanghai Pujiang is the most recognized name in the manufacturing of PWS having produced cables for over 50 suspension bridges in the past ten years. PWS are stands containing a number of wires that are bundled together into hexagons. These bundles contain 127 wires or more. The process of erecting the bundles into the main cable is much faster than aerial spinning. There are documented cases where months of spinning were eliminated. In the case of Self-Anchored Suspension Bridges, such as the New Bay Bridge in San Francisco, Aerial Spinning cannot be performed and PWS is required.
