What Are the Advantages and Uses of Unbonded PC Strands?

As a supplier of unbonded PC steel strands with many years of experience, Tianjin Yuanxian High-tech Materials Co., Ltd. has always been driven by technological innovation and quality assurance, providing high-performance and high-reliability prestressed solutions for global engineering construction. Its products help various engineering projects to operate safely and efficiently through unique structural design and strict production processes.

1. Structural Design

The Unbonded PC Strand produced by our company adopts a three-layer protective composite structure:

- High-Strength Steel Core: Selected 1860MPa grade low-relaxation high-carbon steel wire, with complete diameter specifications (12.7mm, 15.2mm, etc.), to ensure the ultimate bearing capacity and anti-fatigue performance;

- Special Anti-corrosion Grease: Self-developed high-performance lubricating anti-corrosion grease, the friction coefficient is reduced by 30%, effectively reducing tension loss and delaying steel wire aging;

- HDPE Protective Sheath: Using imported high-density polyethylene raw materials, seamless wrapping is achieved through a patented coating process, and the weather resistance and wear resistance far exceed the industry standard.

2. Guarantee of Production Process

Our factory keeps pace with the times, relying on intelligent production lines and full-process quality control systems to ensure the excellent performance of every meter of steel strand:

- Automated cold drawing and stranding: German imported equipment realizes precise processing and stable stranding of steel wire, eliminating internal stress;

- Online detection system: Real-time monitoring of grease thickness, sheath uniformity and mechanical parameters, with a defective rate of less than 0.1%;

- Customized production: Supports personalized orders with special strength grades, diameter specifications and anti-corrosion requirements.

3. Core Advantages

4. Application Fields Demonstrate Strength

The products produced by our factory have won the trust of many customers and established deep cooperative relationships. Its main application areas include:

- Super high-rise buildings: Helping 300-meter+ skyscrapers to achieve large-span spatial structures;

- Cross-sea bridges: As the core material of the cable-stayed cable, it ensures the wind and earthquake resistance of the bridge;

- Energy infrastructure: The preferred solution for key parts such as nuclear power plant containment and LNG storage tanks;

- Old building renovation and reinforcement: Through the external prestressing technology, the bearing capacity of existing buildings can be efficiently improved.
