I. What is copper-plated steel fiber

Copper-plated steel fibers, by coating the surface of steel fibers with a layer of copper, not only retain the original high strength and high modulus characteristics of steel fibers, but also significantly enhance their corrosion resistance and electrical conductivity. Copper-plated steel fibers possess multiple properties such as reinforcement, strengthening, corrosion resistance, and crack resistance. They are golden yellow in color, with a length of 13mm and a diameter of 0.2mm. These characteristics enable copper-plated steel fibers to maintain stable performance even in harsh environments.

II. How does it differ from ordinary steel fibers

Compared to ordinary steel fibers, the biggest difference of copper-plated steel fibers lies in the copper coating on their surface, which significantly enhances their corrosion resistance and durability. Furthermore, copper-plated steel fibers can also improve the conductivity of concrete, making them widely used in floor coatings, industrial wear-resistant floors, anti-static floors, and other fields. Ordinary steel fibers do not exhibit these properties.

III. What are the advantages of copper-plated steel fibers

1. Corrosion resistance: The copper coating of copper-plated steel fibers effectively prevents corrosion, thereby extending the service life of the steel fibers.

2. Electrical conductivity: Copper-plated steel fibers can enhance the electrical conductivity of concrete, making them widely used in floor coatings, industrial wear-resistant floors, anti-static floors, and other fields.

3. Wear resistance: Copper-plated steel fibers possess high tensile strength and resistance to stretching, significantly enhancing the durability and load-bearing capacity of concrete.

4. Convenient for construction: Copper-plated steel fibers can be directly added to concrete without requiring special operational procedures.

IV. What are the application areas of copper-plated steel fibers

1. Concrete reinforcement and crack resistance:

One of the most widespread applications of copper-coated steel fibers is as a reinforcement material in concrete. Their high strength and excellent crack resistance make concrete structures less prone to cracking under load, enhancing the overall integrity and durability of the structure. Copper-coated steel fibers, with their high strength, are particularly suitable for applications such as bridge decks and road surfaces, which require heavy loads and frequent traffic flow.

2. Wear-resistant materials:

The wear resistance of copper-plated steel fibers makes them an ideal material for manufacturing wear-resistant flooring, wear-resistant pipelines, and other products. These products require long-term use in high-friction environments, and the addition of copper-plated steel fibers significantly enhances their service life. Ultra-high-strength RPC copper-plated steel fibers not only possess high strength, tensile resistance, and wear resistance, but are also suitable for multiple fields such as high-speed railways, RPC covers, and high-performance concrete prefabricated parts, demonstrating their wide applicability.

3. Electromagnetic shielding materials:

Due to copper's excellent conductivity, copper-plated steel fibers can also be utilized in the manufacture of electromagnetic shielding materials, safeguarding electronic devices from electromagnetic interference. This characteristic is particularly crucial in fields such as electronic communication, aviation, and aerospace.

V. Production Process： 

The production process of copper-plated steel fibers primarily involves steel fiber preparation, surface treatment, and copper plating. Among these steps, the copper plating process is a crucial one, as it directly affects the corrosion resistance and conductivity of the product. By controlling the thickness and uniformity of the copper plating layer, the comprehensive performance of the product can be optimized.

VI. Precautions:   

Dosage control: When using copper-plated steel fiber reinforced concrete, it is necessary to strictly control its dosage. Excessive dosage may lead to deterioration of the workability of the concrete, affecting the construction quality.

Uniform dispersion: Ensure that the copper-plated steel fibers are uniformly dispersed in the concrete, avoiding clumping, so as to fully exert their reinforcing effect.

Construction environment: In harsh construction environments, such as high temperature, high humidity, or corrosive media, special attention should be paid to the corrosion resistance of copper-plated steel fibers. Additional protective measures can be taken if necessary.
