PC strand, also known as prestressed concrete strand, is a type of steel reinforcement used in construction. It is made by taking high-tensile steel wire and subjecting it to a process known as prestressing.
YUANXIAN Product Page
During the prestressing process, the steel wire is stretched to a specific tension and then anchored in place. This creates a compressive force within the concrete that counteracts any tensile forces that may occur during the life of the structure. As a result, PC strand is able to provide a higher level of strength and stability to concrete structures than traditional reinforcing methods.
PC strand is typically made from high-carbon steel and is available in a variety of sizes and grades to suit different construction needs. The wire is made by drawing it through a series of dies to achieve the desired size and shape.
PC strand is used in a variety of construction projects, including bridges, buildings, and other infrastructure projects. It is used to reinforce concrete in pre-tensioned and post-tensioned applications. It is also used in the construction of parking garages, stadiums, and other large structures. It can also be used in the repair and retrofitting of existing structures. One of the most common uses of PC strand is in pre-tensioned concrete. This method of prestressing involves stretching the PC strand before the concrete is poured, and then anchoring the strand in place. The concrete is then poured around the strand, creating a compressive force that counteracts any tensile forces that may occur during the life of the structure.
In addition to its strength and stability benefits, PC strand also offers other advantages over traditional reinforcing methods. For example, it requires less steel overall, which can reduce the overall weight of the structure and decrease the amount of steel needed to be produced. This can also help to reduce the overall cost of the project.
Another advantage of PC strand is that it can be easily cut and bent to fit into tight spaces, making it an ideal solution for structures with complex or irregular shapes. Additionally, its smooth surface can help to reduce the risk of concrete cracking and improve the durability of the structure.
PC strand is made in many countries worldwide, with the United States being the largest producer. In the US, Madison Steel is one of the leading distributors of PC strand. They offer a wide range of products for different applications such as bridges, buildings, and other infrastructure projects.
Overall, PC strand is a versatile and reliable reinforcement option for concrete structures. Its ability to provide a high level of strength and stability makes it an ideal choice for a wide range of construction projects. With the help of logistic professionals like Madison Steel, Prestressed strand is widely available and can be easily incorporated into any construction project.

In order to improve service performance of constructions, we can put prestressing force ahead. Structures or constructions receive prestressing force ahead can completely or partially bear the load caused by the tensile stress, therefore it can avoid structural damage or delay the structural damage time. Our company is one of the leading manufacturers of PC wire, PC strand and reinforcing steel bars. Our prestressing concrete wire strand with high bonding force, low relaxation and high corrosion resistance is your best choice. We have various kinds of PC wire and PC strand, and can supply products according to different diameters, different length, different surface treatment and different standards. All can be produced according to customers' special requirements.
Kinwey offers Prestressed Concrete Wires (pc wire) in mainly two types: Mono pc wire and Multi-wire strand.
PC steel wires are widely used in concrete construction industry for pre-stressed steel structures: large-span bridges ( stay cable system), overhead crane beam, cement poles, coal mines rock-soil anchoring project, multi-storey frameworks (slab and hollow floors), subway, railway sleepers, dams, shell safety of nuclear power stations, high-rise buildings (television tower, water towers, concrete silo, sewage treatment, hydropower project, stadiums) and etc.
Quality: ASTM A-416, BS , JIS G, the standards and cutomized specifications.
Common wire materials for production: High tensile wires, plain or galvanized.
The process involves the continuous heating and stretching of a cold drawn high-carbon steel wire to produce a finished product with a much improved yield stress and greatly reduced load relaxation.
Prestressing concrete steel wire can be divided according to wire diameter, the intensity level, the surface coating or cross-section:
1. According to diameter, PC steel wire can be categorized as: 4mm, 4.8mm, 5.0mm, 5.1mm, 6.0mm, 6.35mm, 7.0mm, 7.8mm, 8.0mm, 9.0mm, 10.0mm, 11mm, 12mm and so on.
2. According to tensile strength, pc wire can be classified as: MPa, MPa, MPa, MPa and MPa.
3. According to the surface coating, pc wire can be classified as: uncoated prestressed steel wire, prestressed epoxy coated steel wire and galvanized prestressed steel wire.
4. According to forms of the surface, it can be classified as: Round plain wires, spiral ribbed (spiral ribbed or helix grooved) steel wires, crimped wires, slotted (indented) wires, and so on.
5. According to wire treatment process, pc wire can be categorized as follows: cold-drawn pc wire and low relaxation pc wire.
6. According to wires applied, pc wire can be classified as single individual pc wire and helically stranded wire ( pc strand).
7. According to applications, pc wire / strand can be divided into:
Un-bonded strand: zinc coated, grease filled; uv stabilized polymer sheath, for post tensioning
Bonded strand, retardant, galvanized bright, with PE shielding, for stable cable, suspension wire cable for bridge construction
8. According to structures, stranded wire can be classified into 2 wire strand, 3 wire strand or 7 wire strand mostly.
Post-tensioning is very useful to defeat the natural weakness of concrete in tension and to optimize its strength in compression. In concrete structures, using high-tensile steel wire / strand placed in the element prior to casting will:
1, Reduces occurrence of cracks .
2, Increase in durability.
3, Less deformations (improved serviceability).
4, Increase in shear capacity.
Since concrete is weak in tension, the reinforcing steel bar / rebar is used inside concrete for strengthening and reinforcing the tensile strength of concrete. Reinforcing steel bars are used to absorbs the tensile, shear, and sometimes the compressive stresses in a concrete structure.
