Wire For Suspension Bridges
TechStar represents Baosteel and Shanghai Pujiang Cable outside of China. Both of these companies from Shanghai, China. Wire is produced by Baosteel and Shanghai Pujiang produces cables. Parellel wire is used as the main cable for all suspension bridges. The cable is erected in one of two ways. The original way, as Roebling did it, is aerial spinning. Boasteel produces the wire in coils and this is then spun back and forth across the bridge over the towers and back to the anchorages until the cable is complete.
