0.2mm×13mm 2850MPa Corrosion Resistant Copper Coated Micro Steel Fiber for UHPC

Coppered Micro Steel Fibres Product Overview

Copper-coated micro steel fibre is an advanced concrete reinforcement material. Made of high-strength steel wire with a uniform electrolytic copper coating, it boasts a fine diameter, ultra-high tensile strength, and superior rust resistance, serving as a key raw material for UHPC and projects in all kinds of corrosive environments.

Coppered Micro Steel Fiber Key Specifications

Coppered Micro Steel Fiber Technical Advantages

◆ Uniform copper coating

     A uniform electrolytic copper layer greatly improves conductivity and long-         term corrosion resistance, effectively resisting damage from chloride ions      

    and salt-alkali corrosion.

◆ Micro-dimension design

      Fine wire diameter ensures the fibre disperses evenly in the concrete matrix, with no agglomeration, for a stable reinforcement 

      effect.

◆ Wide compatibility

      Fully compatible with various cementitious materials, suitable for concrete with strength grade of 40–80 MPa.

◆ Super high strength

      Tensile strength ≥2850 MPa, effectively inhibits microcracks and improves concrete toughness, flexural and impact resistance.

◆ Good workability

     Smooth surface won’t block pumping equipment, suitable for shotcrete, precast components and on-site pouring.

RFQ

1. Q: Will the micro steel fibre clump or tangle during mixing?

     A: Featuring a micro-dimension design, our fibre disperses evenly in concrete without clumping or tangling.

2. Q: What are the advantages of copper coating?

     A: The integrated copper layer greatly improves rust and corrosion resistance, suitable for coastal, chemical and saline-alkali 

          environments.

3. Q: What is the recommended dosage for different projects?

      A: 20–30 kg/m³ for civil floors; 30–50 kg/m³ for tunnel shotcrete; 60–90 kg/m³ for mine & metallurgy heavy abrasion areas; 40–90 

           kg/m³ for dams, wharves and revetments; 30–80 kg/m³ for coastal, chemical and saline-alkali areas.

4. Q: What’s the difference between copper-plated micro steel fibre and ordinary steel fibre?

     A: It has higher tensile strength, better corrosion resistance and more uniform dispersion. Its service life is 2-3 times longer than         

          common steel fiber.

5. Q: Is copper-plated micro steel fiber cost-effective?

     A: Though the unit price is higher, it requires lower maintenance and replacement frequency, bringing better comprehensive 

           economic benefits in long-term projects.

6. Q: Do you support bulk orders and customised packaging?

     A: Yes. We provide bulk supply and support customised packaging in line with customer requirements.

7. Q: What is your delivery time for steel fiber orders?

    A: Regular orders can be delivered within 7-15 working days. We can arrange urgent shipment for large projects.
