7-Wire Epoxy Coated PC Strand
Primary Advantages
Our seven-wire prestressing steel strand is designed with epoxy-filled interstices, minimizing the migration of corrosive substances through capillary action or hydrostatic forces.
During the continuous pinhole detection process, no more than 2 pinholes are detected per 100 feet (30 meters), ensuring superior quality and durability.
The epoxy-filled wires tightly bind the seven steel strands together, creating a friction-reducing layer between the wires. This significantly reduces dislocation and friction under load, preventing fretting wear fatigue and enhancing fatigue resistance. Additionally, the tensile strength of filled epoxy steel strands is 3–4% higher than standard single-wire epoxy-coated steel strands.
Why Choose This Epoxy-Coated PC Strand?
Our Epoxy Coated PC Strand offers exceptional chemical and abrasion resistance. It effectively addresses common prestressed steel strand failures caused by corrosion stress, providing a long-lasting anti-corrosion solution and substantially extending the service life of structures.
What Sets Our Product Apart?
We provide a reliable quality guarantee for every epoxy-coated steel strand we manufacture, ensuring consistent performance and longevity.
As a modern prestressed material, our Epoxy Coated PC Strand has become widely used in bridge construction and other infrastructure projects across China. Its excellent anti-corrosion properties make it ideal for various cable structures, including:
Cable-stayed cables
External and internal cables
Suspension cables
Tie cables
Geotechnical anchor cables
Anchor prestressed cables
With its superior durability and strength, our prestressed steel strand is the preferred choice for long-lasting, corrosion-resistant construction projects.

As per the client's requirement
Q: What is an Epoxy Coated PC Strand?
A: An Epoxy Coated PC Strand is a seven-wire prestressing steel strand coated and filled with epoxy resin to provide excellent corrosion resistance. It is a type of prestressed material widely used in bridges and cable structures.
Q: What are filled epoxy-coated strands?
A: Filled epoxy-coated strands have epoxy resin filling the interstices of the seven wires. This minimizes corrosion, reduces friction between the wires, prevents fretting wear fatigue, and increases tensile strength compared to standard epoxy-coated steel strands.
Q: Where can I use epoxy-coated steel strands?
A: Our epoxy-coated steel strands are ideal for applications such as cable-stayed cables, suspension cables, tie cables, internal and external cables, geotechnical anchor cables, and anchor prestressed cables.
Q: How are filled epoxy steel strands different from regular prestressed steel strands?
A: Filled epoxy steel strands provide higher tensile strength, better fatigue resistance, and superior chemical and abrasion resistance. Unlike ordinary prestressed steel strands, they effectively prevent corrosion stress failure, ensuring a longer service life.
Q: Why should I choose this 7-wire epoxy-coated PC strand?
A: Choosing our seven-wire prestressing steel strand guarantees high-quality, long-lasting performance. With minimal pinholes, tight epoxy filling, and a friction-reducing layer, it enhances fatigue resistance and reliability in demanding projects.
