XQV Epoxy-Coated PC Strand – Fusion-Bonded Epoxy Coated Prestressed Steel Strand for Corrosive Environments

High-Performance Anti-Corrosion PC Strand – Ideal for Coastal Bridges, Marine Structures & Industrial Facilities

Product Introduction

XQV epoxy-coated PC strand is an anti-corrosion steel strand with an epoxy resin coating applied to the surface of prestressed steel strands. By isolating the steel substrate from external corrosive media (such as moisture, chloride ions, oxygen, etc.), it significantly enhances corrosion resistance and is suitable for prestressed engineering in highly corrosive environments such as high-humidity areas, coastal regions, and industrial zones.

Key Features & Advantages

🛡️ Anti-Corrosion Protection: Epoxy resin coating isolates steel substrate from moisture, chloride ions, and oxygen.

💪 High Tensile Strength: Substrate steel strand with tensile strength ≥1860 MPa.

🔬 Thermosetting Epoxy Coating: Excellent chemical stability, acid/alkali resistance, and strong adhesion.

🔧 Pretreatment Process: Acid pickling or sandblasting ensures clean and rough surface for optimal coating adhesion.

⚙️ Two Coating Types: Single-wire coating (individual wire coating) or overall filling type coating.

🔥 High-Temperature Curing: Uniform and continuous coating layer for consistent protection.

🌊 Suitable for Harsh Environments: Ideal for high-humidity areas, coastal regions, and industrial zones.

📜 Compliant Standards: Manufactured to GB/T 25823, JT/T 737, GB/T 21073, and ASTM A882.

Application

XQV Epoxy-Coated PC Strand is specifically designed for prestressed concrete structures in aggressive environments where corrosion resistance is critical. Typical applications include:

Bridge Decks & Highways: Used in bridge decks exposed to deicing salts, coastal bridges, and highway structures requiring long-term durability. The epoxy coating prevents chloride-induced corrosion.

Parking Structures: Applied in post-tensioned parking garages where chloride penetration from vehicles is a concern. Ensures 50+ years of service life.

Marine & Coastal Structures: Used in piers, wharves, sea walls, and offshore platforms exposed to saltwater spray and tidal zones.

Water & Wastewater Treatment: Applied in water tanks, treatment plants, and containment structures exposed to chemicals and high humidity.

Underground Structures: Used in tunnels, subways, and foundation systems where groundwater contains aggressive chemical agents.

Precast Concrete Elements: Applied in precast beams, piles, and slabs for coastal or industrial environments requiring high durability.

Industrial Facilities: Used in chemical plants, power stations, cooling towers, and other facilities with corrosive exposure.

Rock & Ground Anchors: Applied in permanent ground anchors for slope stabilization in corrosive soil conditions.
