Bridge Tension Steel Strands made up of stranded steel wires can be divided into prestressed steel strands, unbonded steel strands, galvanized steel strands, etc.
Galvanized steel strands are commonly used for load-bearing cables, pull wires, reinforcement cores, etc. It can also be used as a ground wire for overhead power transmission, blocking cables on both sides of roads, or structural cables in building structures.
Prestressed strands Commonly used prestressed strands are uncoated low relaxation prestressed
strands, and some are galvanized.

Prestressed cable is mainly for the use of prestressed concrete structure reinforced. Such as large -span bridges on railway and highway, overhead crane beam, rock-soil anchoring project, multi-story industrial buildings, stadiums, coal mines and etc.
The prestressed tensioning construction design of the prestressed steel strand controls the tensioning force, which refers to the tensioning force of the steel strand before the anchoring fixture after the prestressed tensioning is completed. Therefore, in the calculation of the theoretical elongation of the prestressed tension of the steel strand, the distance between the anchor points at both ends of the steel strand should be used as the calculated length of the steel strand, but the controlled tension of the steel strand during prestressed tensioning The tension is controlled at the jack tool anchor, so for the convenience of control and calculation, the distance between the anchor points at both ends of the steel strand, plus the working length of the steel strand in the tension jack, is used as the pre-strand of the steel strand.
