In this article, I, as a manufacturer of PC strands, explain what is the use of PC strands.

PC strand, or prestressed concrete strand, is a high-strength steel wire used to reinforce concrete structures. It is made by cold drawing high-strength steel wire into strands, which are then heated and stretched to prestress the strand. PC strand is used in a variety of concrete construction applications including bridges, buildings, car parks, and other types of infrastructure.

One of the main benefits of using the PC strand is that it allows concrete structures to be designed with longer spans and smaller cross-sections, thus using less material and making the construction of the structure more economical.PC strand also has a high tensile strength, which means that it can withstand large amounts of stress without breaking. This makes it an ideal reinforcement material for concrete structures subjected to heavy loads, such as bridges and multi-story buildings.

In addition to its tensile strength, the PC strand has good corrosion resistance, which means it retains its strength and integrity even in harsh environments. This makes it a suitable reinforcement material for use in marine environments and highly polluted areas.

PC strand is often used in conjunction with other reinforcement materials such as rebar to provide additional strength and support to concrete structures. It is also used with prestressed concrete beams, which are prestressed using PC strands before being placed into the structure. This allows the beam to carry heavy loads without cracking or deforming.

PC strand is available in a range of sizes and strengths and is usually supplied in reels or spools for ease of handling and installation. It is commonly installed in concrete structures using one of several methods, including stressed tendons, post-tensioning, and pre-tensioning.

Overall, the PC strand is an important reinforcement material that is widely used in the construction of concrete structures. It enables designers to create more efficient and economical structures that can withstand heavy loads and maintain their integrity in harsh environments.

General Intro

Prestressed Steel Strand is an engineered steel PC wire with multi-sides profiles, special for reinforcement of prestressed concrete structure.

PC steel strand is the simplified term describing Prestressed Concrete Steel Strand Wire. With the advantages of high tensile strength and good corrosion resistance at elevated temperature, PC strand wire is used in heavy loading concrete constructions. It is made with galvanized steel wire or carbon steel wire through drawing, twisting or stranding and stabilizing. The stranded wire structures allow high tension and less distortion in uses.

Common sizes: 9.3 mm. 9.6.12.7, 12.5, 12.9, 11.11, 11.3, 15.24 and 15.7 mm.

Raw Materials: High-carbon steel wire rods, SWRH 82B

Processing: Continuous drawing by means of big reduction of area, twist, stabilizing treatment

Features: High tensile strength, low relaxation, stable modulus of elasticity, stress-relieved, firm connection with concrete, low stress, stable construction, good combination with steel reinforced concrete; saving material, reducing distortion and construction weight, increasing the abrasion resistance, water resistance, stiffness.

Standards We Follow: Concreate PC Strand confirms to the technical standards such as GB/T , GB/T , ASTM A-416, BS , JIS G or the standards agreed by both of the customers and us.

Prestressed steel concrete strand or PC strand can also be supplied in various forms for pre- or post-tensioning applications, with plain or galvanized material ranging from 3 wires, 7 wires, 19 wire and compacted construction.
Packing: Export anti-rust packing with vapors corrosion inhibiting technology and 3 coatings. There are two wooden pallets on the bottom.

Application
Our PC strand is mainly used for the reinforcement of prestressed concrete structures, such as large-span railway and road bridges, major bridges, silos, buildings, dams, floor slabs, foundations, large concrete vessels, atomic reactor buildings, stadiums, airport hangers, pre-cast segments, crane beams, anchorages and multi-storey industrial buildings etc.
Our PC strand is also used for the construction of highways, poles and water towers in civil construction, and energy source sea transportation, house buildings, water control projects, and rock and earth anchoring components to increase the tensile force.
