Steel strands for prestressed concrete are made of the high carbon steel wire rods SWRH82B and have the characteristics of high tensile strength, low relaxation, steady modulus of elasticity, relieved stress, and high adhesion with concrete through continuous drawing with large deduction stranding and stabilization treatment to meet the ASTM A 416, GB/T5224-2003, BS5896, JISG3536-88 standards. Especially for large-span concrete constructions in bridges, railway, highway, coal mine, stadiums and multi-storey buildings. Technical Treatment in Production to Ensure Proper Using with Concrete: The pc strands are made of continued drawing with large deduction stranding then stabilizing treatment; The carbon steel materials have high rate of yield strength and ultimate strength, Low relaxation; Steady modulus of elasticity, stress relieved in production, highly fixed with Concrete.

A Prestressed Anchorages consist of wedges, anchor head and bearing plate for transfer the post-tensioning force from the prestressing steel to the structure.  In addition, Its including all accessories for grouting. Furthermore, Stressing anchorage is the most common form of post-tensioning system. It is widely used in concrete structure and soil / rock retaining walls. post tensioning anchorages consist of wedge, anchor head, bearing plate and spiral reinforcement. Flat Anchor: The Flat Anchor accommodates a maximum of five strands in a single plane, allowing them to deviate into one oval duct. This design is primarily intended for use in thin structural members. It is commonly employed in the transverse post-tensioning of the top slab in box-girder bridges and prestressed flat slabs. The system connects strands that run through steel or flat corrugated galvanized steel ducts, which are manufactured in our facility. Each strand is individually stressed using a mono-strand jack.

PC steel bars are mainly used in the construction industry. It is the main steel for pipe pile foundations. It has high strength, small amount of metal materials, convenient use, and easy quality assurance. It has a wide range of uses in the construction industry. Features of PC steel bars PC steel bars (also referred to as Prestressed Concrete Steel bars) is high tensile, low relaxation steel wire made from high-carbon steel and widely used for prestressed and post-tensioning technology in various shapes of PC structures. It has the following characteristics and advantages: ● High tensile strength and low relaxation ● More bonding stress between wire and concrete ● Stable modulus of elasticity Properties Product Name PC steel bar Type of Surface Spiral Ribbed, Indented, Plain Materials SWRH82B Diameter 4.0mm, 4.8mm, 5.0mm, 6.0mm, 7.0mm, 8.0mm, 9.0mm Tensile Strength 1470Mpa-1770Mpa Relaxation (%) ≤2.5 Elongation (%) ≥3.5 Standard ASTM A 421, GB/T5223, BS5896, JISG3536, and required standard. Packing Packed in coils (around 700-1300kg/coil). Each coil is strapped by steel bands at 8 places, fully wrapped with anti-rust plastic & PP woven sheet. Application PC Wire is characterized with high tensile strength and low relaxation. It's widely used in production of prestressed spun concrete poles, PHC Piles, in construction of large scale railroad, high-way bridges, building trusses, overhead crane beams, industrial and civil prefabricated concrete slabs, wall board, power station, etc.

In the application of pre-tensioned concrete, the pre-stressed steel wire is initially tensioned to approximately 70 to 80% of the minimum specified breaking load of the steel wire before the concrete is cast. Once the concrete sets to a certain degree, the pre-tensioned steel wire is released, and this induces compressive stress in the concrete. This compressive stress helps offset the tensile stress caused by the loads acting on the concrete member. For effective pre-tensioning, it is crucial to establish a strong bond between the steel wire/bar and the concrete. This bond allows the desired compressive force to be efficiently transferred from the steel wire to the concrete. One method to improve the bond strength and achieve a consistently low transmission length is by introducing regular indentations of a specified shape on the surface of the steel wire/bar. These indentations can be slotted in opposite or 120-degree or 90-degree planes. To create indented steel wire or rod, a process known in the industry is to perform intermittent indentation on the wire's surface using appropriate indenting rolls. Typically, this indentation process takes place on a wire- drawing machine, where the wire is pulled through the indenting rolls to achieve the desired pattern.
