When prestressed concrete structures are exposed to moisture, chloride, salt, or other corrosive conditions, protecting the prestressing steel becomes an important part of long-term durability. Epoxy coated PC strand provides a protective epoxy barrier around high-strength prestressing steel, helping reduce exposure to corrosive elements while maintaining the mechanical performance required for prestressed concrete applications.
At Tianjin Wasungen Metal Products Co., Ltd., we supply epoxy coated prestressing strand for infrastructure and construction projects where corrosion protection and reliable long-term performance are important. Our products are available in commonly used diameters, including 12.7mm, 15.2mm, and 15.7mm, with specifications and coating options selected according to project requirements.
Our epoxy coated PC strand is suitable for applications such as bridges, parking structures, marine and coastal infrastructure, industrial facilities, and other prestressed concrete projects exposed to aggressive environments.
The epoxy coating creates a protective barrier between the steel strand and external moisture, chlorides, salts, and other corrosive elements. This makes epoxy-coated strand suitable for structures where corrosion protection is a major design consideration.
The seven-wire prestressing strand is manufactured from high-strength steel and is available in different grades and specifications according to project requirements and applicable standards.
A uniform coating helps provide consistent protection along the strand. Coating quality, thickness, and adhesion can be checked during production to support reliable product performance.
Low-relaxation grades are available for applications where controlling long-term prestressing losses is important.
The strand consists of seven helically arranged steel wires, providing the mechanical characteristics required for many prestressed concrete systems.
By helping limit the exposure of prestressing steel to corrosive environments, epoxy coating can contribute to the durability and service life of prestressed concrete structures.
Finished strands can be supplied in suitable coils or reels with protective export packaging for handling and long-distance transportation.
We supply epoxy coated PC strand in several commonly requested diameters. The appropriate size depends on the structural design, required prestressing force, anchorage system, and applicable project specifications.
Available options include:
For specific projects, we can also discuss filled epoxy-coated strand and other related prestressing products according to your technical requirements.
If you already have project drawings or a technical specification, send us the required diameter, grade, quantity, and standard. Our team can help identify a suitable product configuration.
Epoxy coated PC strand is commonly considered for prestressed concrete structures where additional corrosion protection is required.
Typical applications include:
Bridge decks and bridge structures
Marine and coastal infrastructure
Parking structures
Industrial and commercial buildings
Prestressed concrete elements
Infrastructure exposed to chloride or salt
Structures in humid or aggressive environments
Post-tensioning and other prestressing applications where the specified system permits epoxy-coated strand
The exact installation method depends on the structural design and the prestressing system being used. Contractors and engineers should follow the applicable project specifications, stressing procedures, and anchorage requirements.
The main purpose of the epoxy coating is to provide a protective barrier around the steel strand.
In a typical application:
High-strength steel wires are formed into a seven-wire prestressing strand.
The strand receives the specified epoxy coating under controlled production conditions.
The coated strand is inspected for coating quality and mechanical properties.
The finished strand is supplied in coils or reels for use in the specified prestressing system.
During service, the epoxy coating helps reduce direct exposure of the steel to moisture, chlorides, and other corrosive elements.
The actual installation and stressing procedure varies according to the construction system and project design.
We control the production process from steel wire preparation through final packing.
The general production and inspection process includes:
Preparation of high-carbon steel wire
Seven-wire strand formation under controlled production conditions
Heat treatment and mechanical property control where applicable
Surface preparation before coating
Application of fusion-bonded epoxy coating
Inspection of coating quality, thickness, and adhesion
Mechanical testing for strength and elongation
Final inspection, identification, and export packaging
Quality records and testing documentation can be provided according to the product and order requirements.
Typical product specifications may include:
| Item | Typical Specification |

Mechanical properties such as tensile strength, breaking load, elongation, and relaxation should be selected according to the required product grade and applicable standard.
For a quotation, we recommend confirming the required diameter, grade, standard, coating type, quantity, and delivery destination before production.
Our epoxy coated PC strand can be supplied according to applicable international and project-specific requirements.
Depending on the product specification, relevant standards may include:
ASTM A882
EN 10138
GB/T 5224
The applicable standard should be confirmed based on the specific product, coating system, and project requirements.
Mill test reports and relevant inspection documentation can be provided according to the order requirements.
For projects requiring additional protection of the spaces between the steel wires, filled epoxy coated strand may be considered.
Filled epoxy coating helps reduce the pathways through which moisture and corrosive agents could reach the steel core.
Whether filled or unfilled epoxy-coated strand is appropriate depends on the project design, specification, and applicable requirements.
If your project specifically requires filled epoxy coated PC strand, provide the required diameter and standard when requesting a quotation.
We supply epoxy coated pc strands to projects across multiple regions.
South America:
Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, Venezuela
Central Asia:

Epoxy coated PC strand is a high-strength seven-wire prestressing strand covered with a protective epoxy coating. The coating helps protect the steel from moisture, chlorides, salt, and other corrosive elements in demanding environments.
It is used in specified prestressed concrete applications where additional corrosion protection is required. Common applications include bridges, parking structures, marine and coastal infrastructure, and other structures exposed to aggressive environments.
Plain PC strand does not have an external epoxy protective layer. Epoxy coated PC strand has a protective coating designed to reduce the steel's exposure to corrosive elements. The appropriate option depends on the structural design and project requirements.
Neither coating system is universally better for every project. The appropriate choice depends on corrosion exposure, structural requirements, design specifications, applicable standards, and the required protection system. Epoxy-coated strand is commonly considered when a continuous protective barrier against corrosive exposure is required.
