PC Strand, the prestressed concrete steel strand, is a twisted steel cable composed of 2, 3, 7 or 19 high strength steel wires and is stress-relieved (stabilized) for prestressed concrete or similar purposes. PC Strand is mainly used for concrete structure, such as railway and highway, overhead crane construction, multi-floor industrial building and etc. Products have been widely applied to the engineering construction of large scale of railroads, highways, bridges.
According to the number of steel wire in a strand: 2 wire strand, 3 wire strand, 7 wire steel strand and 19 wire steel strand.
According to the surface morphology can be divided into smooth steel strand, scoring strand, mold pulling strand (compact), coated epoxy resin steel strand.
Stranded wire types according to the surface shapes: smooth plain steel strand, indented steel strand, Helix strand, compact steel strand (compact), Epoxy coated PC Strand (7 wires individually coated), etc.
It can also be categorized by wire diameter, or intensity level, or by standard.

Common sizes: Diameter 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm indented PC wire for metal building materials.
Wire Shapes: Plain wire, Spiral ribbed steel wire
Standard: GB/T, ASTMA421, BS, JISG, ISO, EN
Coil weight: 1&#;3 tons
Elongation: 3.5%
Tensile Strength:Mpa-Mpa
Function: Low relaxation pc wire is used for prestressed steel structure, prestressed and post-tensioning, in large, medium and small sizes.
In the description and list of the table we often see, there are 15&#;7Φ5, 12&#;7Φ5, 9&#;7Φ5 and other specifications of the prestressed steel strand.
To 15&#;7Φ5, for example, 5 said a single diameter 5.0mm of steel, 7Φ5 said seven of the steel wire to form a strand, and 15 that the diameter of each strand of 15mm, the total meaning is &#;one The beam consists of 7 strands of diameter 15 mm (each having a total diameter of about 15.24 mm, a dimensional deviation +0.40 -0.20; a diameter of about 5.0 mm per filament).
The general sectional area is calculated according to 140mm ^ 2. The theoretical breaking value is 140 * = 260.4kN, which can withstand the tension of 156.24&#;169.26kN according to the prestressing standard of 60% -65%.
Using high-carbon steel wire rod, after surface treatment of cold drawn into steel wire, and then by the strand structure will be a number of steel wire stranded into shares, and then through the elimination of stress from the stabilization process.
In order to extend the durability, the wire can have metal or non-metallic coating or coating, such as galvanized, epoxy resin coating. In order to increase the bond strength of the concrete, the surface can have nicks and so on.
The prestressed strands of the mold are twisted to form a mold compression process, the structure is more compact, and the surface layer is more suitable for the anchor.
Production of unbonded prestressed steel strand (unbonded steel strand) using ordinary prestressed steel wire, coated with oil or paraffin after the package of high-density polyethylene (HDPE) into.
The main characteristic of the prestressed steel strand is high strength and relaxation performance is good, the other when the more straight. Common tensile strength level of MPa, as well as ,,,, MPa and the like intensity level. The yield strength of this steel is also higher.
