The Individual Epoxy Coated 1x7 PC Strand is a premium Prestressed Steel solution engineered for superior performance in demanding structural applications. Designed with a single wire configuration of seven high-strength wires twisted together, this strand delivers exceptional tensile strength while maintaining flexibility and ease of installation. The advanced epoxy coating serves as a robust protective barrier against moisture, chloride ingress, and chemical exposure—making it an ideal choice for infrastructure projects located in coastal zones, industrial environments, or areas subject to aggressive weather conditions.
This corrosion-resistant reinforcement product meets international standards such as ASTM A722, EN 10138-3, and ISO 10400, ensuring consistent quality and long-term durability. Its smooth surface finish enhances bond characteristics with concrete, minimizing the risk of delamination and cracking over time. Unlike conventional bare strands, the epoxy layer significantly extends service life by preventing rust formation and degradation due to environmental stressors—a critical factor in sustainable construction practices across bridges, highways, and precast elements worldwide.
Key features include high load-bearing capacity, excellent anchorage performance, and compatibility with both bonded and unbonded post-tensioning systems. Available in multiple diameters (from 9.5mm to 15.2mm) and customizable lengths, this strand supports tailored engineering solutions for diverse project specifications. With its lightweight design and reduced maintenance requirements, it offers cost-effective value throughout the entire lifecycle of reinforced concrete structures—from initial construction through decades of operational use.
Ideal for use in bridge decks, parking structures, tunnel linings, marine piers, and high-rise foundations, this epoxy-coated 1x7 PC strand ensures reliable structural integrity under dynamic loads and extreme climatic conditions. It’s particularly suited for engineers seeking durable, low-maintenance alternatives to traditional steel reinforcement in regions where saltwater exposure, freeze-thaw cycles, or chemical contamination pose significant challenges.
Engineered by Chunpeng Group—a globally recognized manufacturer with more than three decades of expertise in prestressed concrete materials—this strand combines precision manufacturing techniques with rigorous quality control processes. As part of their comprehensive portfolio that includes unbonded strands, galvanized variants, and weather-resistant options, the epoxy-coated 1x7 PC strand stands out as a dependable choice for modern infrastructure development.
Users consistently report improved constructability, enhanced bond strength, and extended service life compared to non-coated alternatives. Many engineers appreciate how the product simplifies installation while delivering predictable performance even in harsh environments—reducing long-term repair costs and increasing overall project resilience.
Common questions often revolve around the longevity of the epoxy coating under prolonged exposure, the recommended tensioning procedures, and compatibility with different grouting methods. Manufacturers typically advise proper handling during transport and storage to avoid mechanical damage to the coating, and recommend adherence to standard installation protocols for optimal bond development and structural safety.
