As we are aware that Prestressed Concrete Wire (PC Wire) is reputed for low-relaxation that gives compression stress to compensate tensile stress to be exerted on a structure from an external force. It has got the varied application in the modern construction and building industry. PC wire is extensively used in major construction projects of cast concrete components. Because of its strength and elasticity, PC wire is used in bridges and high-rise buildings. To make it, drawing lines have to perform extremely effectively. Thus it is used ranging from railway track sleepers, ground stabilizing piles, floor beams, and pipe systems such as bridges, crane beams, cement poles, Prestressed concrete pressure pipe, multi-factory frameworks, subway, railway sleepers, poles, dams, nuclear power plants, high-rise buildings and houses, anchor, railway sleepers, panel, and concrete pipes, etc. The foremost reason behind the usage of PC wire in a variety of projects is its capacity to increase strength, and the process predominantly involves the incessant heating and stretching of a cold drawn high-carbon steel wire to manufacture the product with minimum follies that holds much better yield stress that leads to reduced load relaxation. Besides, it also increases the flexibility of a Pre-stressed Concrete Reinforcement that produces desirable results.
PC Wire (Indented) for pole reinforcement
The Indented PC Wire is an integral part of multiple construction projects and it is chiefly used in pole reinforcement. The main features of PC Wire (Indented) include higher fatigue, corrosion resistance this also helps it to perform well at elevated temperature. All these advantages make PC Wire (Indented) the best option for pole reinforcement.

PC Wire for Prestressed Concrete Pipes
Plain hard drawn steel wire for Prestressed concrete for home pipes
IS: 1785 (PT2)
Prestressed Concrete Wire (PC Wire) for concrete pipes holds high tensile strength and produce uniform compressive strength acting as a water barrier between concrete layers, the Prestressing wires produce a uniform compressive pressure in the core that offset tensile stresses in the pipe, and the mortar coating protects the Pre-stressing wires from physical damage and external corrosion. These are manufactured to different international standards and the specific requirement of each customer.

PC Wire for Bridge construction
As mentioned earlier, PC Wire is extensively used in Prestressed concrete construction and one of its important applications can be seen in bridge construction. PC Wires offer consistency in quality waterproofing, finishing, load-bearing capacity, and performance.
PC Wire for rock-soil anchoring Project
Just like the large-span bridges, PC Wire is also used in rock-soil anchoring Projects. The PC wire helps to regulate the soil movement such as ground displacement and subsidence Load distributive compression. It gives high tensile strength and bonding. It also strengthens, stabilizes soil and rock masses and resisting structural movements are achieved by anchoring via Prestressed reinforcement to withstand lateral forces temporary tie-backs in the soil are also necessary for the successful construction of shallow foundations.
