Filled Epoxy Coated Seven Wire Prestressed steel strand
Manufactured in accordance with strict ISO 14655 standards, this strand utilizes prestressing steel that conforms to ISO 6934-4, providing long-lasting corrosion protection and enhanced durability for structural applications.
Primary Advantages
Our Filled Epoxy-Coated Seven-Wire Prestressed Steel Strand is engineered to deliver exceptional strength, durability, and corrosion resistance. Each epoxy-coated prestressing strand complies with the highest international standards, ensuring long-term structural performance in demanding environments.
The Prestressed Steel Strand fully satisfies ISO 6934-4 requirements for characteristic maximum force, 0.1% proof force, and elongation.
The epoxy-coated strand exhibits relaxation losses of ≤4% after 1,000 hours when initially loaded to 70% of its specified characteristic maximum force.
The cured epoxy coating is free from holes, cracks, voids, or any visible damage.
Continuous holiday detection ensures coating integrity — no more than two holidays per 30 meters are permitted, and any defects are promptly sealed using approved materials.
The coating shows no cracking or disbonding during bending or tensile tests, ensuring superior durability and performance.
Why Choose Our Filled Epoxy Coated Seven-Wire Prestressing Steel Strand?
Our Epoxy-Coated Seven Wire Strand undergoes a multi-layer coating process to achieve the ideal thickness, providing enhanced protection and adhesion compared to conventional products. This ensures long-lasting corrosion resistance and mechanical stability in harsh conditions.
The Filled Epoxy Coated Prestressed Steel Strand is ideal for:
External tendons in box girders
Stay cables in bridges and high-rise structures

Q: What is a Filled Epoxy-Coated Seven-Wire Prestressed Steel Strand?
A: It’s a high-strength prestressed steel strand made of seven wires coated with a filled epoxy layer. The epoxy coating enhances corrosion resistance and ensures long-term durability in structural applications.
Q: What are the main advantages of epoxy-coated prestressing strands?
A: The epoxy coating protects the steel from corrosion, reduces relaxation losses, and maintains high tensile strength. It also prevents cracks and voids, ensuring better structural performance.
Q: Where can this product be used?
A: The Filled Epoxy Coated Prestressed Steel Strand is used in external tendons for box girders, stay cables for bridges, high-rise buildings, and other post-tensioned concrete structures.
Q: How is coating quality ensured during production?
A: Each strand undergoes continuous holiday detection to identify coating defects. No more than two holidays per 30 meters are allowed, and all coatings are tested for cracking, adhesion, and uniform thickness.
Q: What sizes are available?
A: We offer 12.7 mm and 15.2 mm epoxy-coated strands, suitable for a wide range of construction and engineering applications.
