Our Galvanized PC strand is a high-strength steel product with a galvanized layer added to the prestressed concrete strand. It has excellent tensile strength, corrosion resistance and low relaxation properties. Galvanized PC Strand is a critical material in modern construction and infrastructure projects requiring high strength, low relaxation, and exceptional corrosion resistance. Its widespread use in bridges, marine structures, and prestressed concrete systems demonstrates its versatility and reliability.
Our galvanized PC strand with strong fatigue resistance and excellent corrosion resistance can meet construction professionals’ requirements and ensure durable, long-lasting, cost-effective solutions for demanding environments.
Ⅰ. Its main application areas are as follows:
1. Bridges and Roads
- Bridge Main Structure: as prestressed tendons of main beams and towers, it improves the bending, compression and seismic resistance of bridges (such as cable-stayed bridge cables and main cables of suspension bridges);
- Highways/railways: used for slope anchoring and roadbed reinforcement to prevent collapse and deformation; blocking cables on both sides of the highway to improve safety.
2. Tunnels and Geotechnical Engineering
- Tunnel support: enhance the stability of surrounding rock and prevent ground subsidence or collapse.
- Slope Protection: fix the ground structure in geological disaster prevention and control (such as landslides and rockfalls).
- Mine Support: underground lifting systems and roadway anchors in coal mines, which can withstand humid and corrosive environments.
3. Concrete Reinforcement for Construction Projects
- Prefabricated Components: used for prestressed concrete beams, slabs and columns to enhance crack resistance and bearing capacity.
- Foundation and Floor Slabs: unbonded galvanized steel strands are suitable for foundation engineering and large-span floor slabs, simplifying construction and preventing corrosion.
4. Structural Cables and Load-bearing Systems: as load-bearing cables, guy wires or reinforcing cores in building structures, improving overall stability.
5. Power Facilities
- Overhead Transmission Ground Wire: acts as a lightning protection ground wire for high-voltage transmission lines.
- Submarine Cable Skeleton: the galvanized layer is resistant to seawater corrosion and protects the cable core.
Ⅱ. Some common attentions in using of galvanized PC strand：
- The deflection tensile coefficient of galvanized PC steel strand normally used (not for bridge cable system) shall not be greater than 28%.
- The deflection tensile coefficient of galvanized PC steel strand for bridge cable system shall be no more than 20%.
- The fatigue test of galvanized PC steel strand in general applications (not for bridge cable system) , steel strand shall not break after being subjected to 2 million times of load.
- The galvanized PC steel strand shall have a continuous zinc layer surface, free of local dezincification, iron exposure and other defects.
