Chunpeng Group presents premium prestressed concrete steel strand engineered for durability, strength, and long-term structural integrity in demanding environments worldwide. As a trusted manufacturer with over three decades of expertise, we specialize in producing high-performance PC steel materials tailored to modern infrastructure needs—from bridges and marine structures to underground tunnels and railway systems. Our advanced steel strands combine superior mechanical properties with exceptional resistance to environmental degradation, making them ideal for projects where reliability and longevity are non-negotiable. Whether you're working on coastal developments exposed to salt-laden air or subterranean installations facing moisture-rich conditions, our products deliver consistent performance under extreme stress and prolonged service life. Key Features: - **Enhanced corrosion protection** through zinc coating technology ensures resilience against chemical exposure, particularly beneficial in saline or humid climates. - **Exceptional tensile strength**, typically exceeding 1860 MPa, supports heavy-load applications such as bridge girders and precast elements. - **Low relaxation characteristics** maintain tension stability over time, minimizing maintenance and maximizing structural efficiency. - **Surface finish options**—smooth or indented—optimize bond strength with concrete matrices, improving load transfer and overall system performance. - **Compatibility with standard
Post-tensioning anchorage systems** allows seamless integration into existing design workflows without requiring specialized components. These high-strength steel strands are manufactured using precision-controlled processes that ensure uniformity, consistency, and compliance with international standards. Each batch undergoes rigorous quality control checks to meet the demands of global construction projects, including those governed by Eurocodes, ASTM, and ISO specifications. Ideal Applications: Engineered for use in critical infrastructure across diverse sectors, our prestressed concrete steel strand excels in: - Bridges, viaducts, and elevated highways requiring long-span capabilities - Marine piers, breakwaters, and offshore platforms exposed to seawater erosion - Underground tunnels, culverts, and subway systems where moisture resistance is vital - Slabs, beams, and railway sleepers located in regions with high humidity or aggressive atmospheric conditions - Structures in industrial zones or urban environments where pollution accelerates material degradation Users consistently report improved project outcomes when specifying our products, citing reduced need for retrofitting, enhanced safety margins, and extended service life even in harsh settings. Engineers appreciate the predictable behavior of our strands under dynamic loading, while contractors value their ease of installation and compatibility with conventional reinforcement techniques. Frequently Asked Questions: What makes your
Prestressed Steel strand suitable for marine environments? The galvanized zinc layer provides a robust barrier against chloride penetration, significantly extending the lifespan of reinforced concrete elements in saltwater proximity. Can this product be used in seismic-prone areas? Yes, its high tensile strength and low relaxation make it well-suited for earthquake-resistant designs, offering reliable performance during cyclic loading events. Is it compatible with both bonded and unbonded tendon systems? Absolutely—it meets the requirements for both types of post-tensioning methods, ensuring flexibility in structural design approaches. How does surface texture affect bonding with concrete? Indented surfaces increase interlock between steel and concrete, enhancing load distribution and reducing slippage at critical junctions. For engineers, architects, and project managers seeking durable, high-efficiency solutions for large-scale civil engineering works, Chunpeng Group’s prestressed concrete steel strand stands out as a globally recognized choice for resilient infrastructure development.
