15.2mm Filled Epoxy Coated 7-Wire PC Strand
The 15.2mm Filled Epoxy Coated 7-Wire PC Strand is a high-performance prestressed steel strand designed for applications requiring advanced corrosion protection and long-term structural durability. The seven-wire strand is fully coated with epoxy, with all inter-wire voids filled to block corrosive agents from penetrating through capillary action or hydrostatic pressure.
Manufactured in accordance with ISO 14655, this prestressing strand uses steel conforming to ISO 6934-4, ensuring reliable mechanical performance, enhanced fatigue resistance, and extended service life in aggressive environments.Key Advantages of 15.2mm Filled Epoxy Coated 7-Wire PC Strand
The Filled Epoxy-Coated Seven-Wire Prestressed Steel Strand is engineered to deliver exceptional strength, coating integrity, and corrosion resistance for demanding structural applications.
Primary Advantages
Complete Epoxy Filling for Superior Corrosion Protection
The epoxy coating fully fills the spaces between the seven wires, effectively preventing moisture, chemicals, and corrosive substances from entering the strand.
Compliance with International Prestressing Standards
The prestressed steel strand fully meets ISO 6934-4 requirements for characteristic maximum force, 0.1% proof force, and elongation, ensuring consistent mechanical performance.
Low Relaxation Loss
The epoxy-coated strand exhibits relaxation losses of ≤4% after 1,000 hours when initially loaded to 70% of its specified characteristic maximum force, supporting long-term prestressing efficiency.
High-Integrity Epoxy Coating
The cured epoxy coating is free from holes, cracks, voids, or visible damage, ensuring uniform protection and long-lasting durability.
Strict Holiday Detection and Quality Control
Continuous holiday detection is applied during production, allowing no more than two holidays per 30 meters. Any detected defects are immediately sealed using approved repair materials.
Excellent Adhesion and Flexibility
The coating shows no cracking or disbonding during bending or tensile testing, maintaining coating integrity under load and movement.
Why Choose Our Filled Epoxy Coated Seven-Wire Prestressing Steel Strand?
Our 15.2mm Filled Epoxy Coated PC Strand is produced using a multi-layer epoxy coating process that achieves optimal coating thickness and strong adhesion. Compared with conventional epoxy-coated strands, this process delivers enhanced corrosion resistance, improved mechanical stability, and reliable long-term performance, even in harsh environmental conditions.
