Our Epoxy-Coated 1x7
PC Strand (12.7mm) is a premium prestressing steel solution engineered for exceptional performance in demanding structural applications. Designed with high-strength, low-relaxation steel wires arranged in a compact 1x7 configuration, this product delivers unmatched durability and long-term reliability. The advanced epoxy coating provides robust protection against environmental degradation, making it ideal for use in marine environments, bridge construction, industrial facilities, and other harsh conditions where corrosion resistance is critical. This strand offers superior tensile strength—typically exceeding 1860 MPa—which ensures efficient load transfer and enhanced structural stability in both post-tensioned and pre-tensioned concrete systems. Its corrosion-resistant properties significantly extend service life compared to uncoated alternatives, reducing maintenance costs and increasing asset longevity. Whether used in highway overpasses, offshore platforms, or commercial buildings, the 12.7mm epoxy-coated strand maintains consistent performance under dynamic stress and extreme weather exposure. Key features include: - High tensile strength for improved structural integrity - Durable epoxy layer that resists chemical attack, saltwater exposure, and moisture ingress - Enhanced bond performance between steel and concrete matrix - Long-term durability in aggressive environments such as coastal zones or chemical processing plants - Compliance with international standards like ASTM A416, EN 10138-2, and ISO 10138 The material’s optimized design supports efficient installation processes while minimizing relaxation losses over time—an essential factor in maintaining pre-stress levels throughout a structure’s lifecycle. Chunpeng Group, a global leader in prestressed concrete materials for over three decades, manufactures this strand using precision engineering and rigorous quality control. As part of their comprehensive portfolio, which includes unbonded strands, galvanized options, and weather-resistant variants, this product exemplifies innovation tailored to modern infrastructure needs. Common applications span bridge decks, parking structures, high-rise buildings, tunnel linings, and wind turbine foundations. It's particularly favored by engineers seeking durable reinforcement solutions for projects requiring minimal upkeep and maximum safety margins. In regions with high humidity, saline exposure, or frequent freeze-thaw cycles, this strand outperforms conventional alternatives due to its protective barrier and mechanical resilience. User feedback consistently highlights the strand’s reliability during long-term installations, especially in challenging climates. Contractors appreciate its ease of handling, compatibility with standard anchorage systems, and reduced risk of premature failure. Engineers value its predictable behavior under sustained loading and its ability to meet stringent regulatory requirements across multiple jurisdictions. Frequently asked questions often center around installation best practices, compatibility with different grouting methods, and expected lifespan under various environmental stresses. While specific details may vary depending on project parameters, the general consensus among users is that proper application of this epoxy-coated strand results in fewer repairs, lower lifecycle costs, and greater confidence in structural performance over decades. Chunpeng Group continues to innovate in
Prestressed Steel technology, offering customizable solutions that align with evolving global infrastructure demands—from sustainable urban development to resilient coastal engineering. This 12.7mm epoxy-coated PC strand stands as a benchmark for quality, safety, and performance in today’s competitive construction market.
