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.
| Parameter | Specification |
|---|---|
| Base Material | Low-carbon steel (SAE 1008-1018 equivalent) |
| Fiber Length | 6/8/13 mm (Custom lengths available) |
| Wire Diameter | 0.14-0.40 mm |
| Tensile Strength | ≥2000 MPa |
| Surface Treatment | Electroplated copper coating |
| Aspect Ratio (L/D) | 15:1 to 93:1 |
◆ 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.

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.
Concrete is everywhere—bridges, houses, highways, dams. It’s the backbone of modern construction. But anyone working with concrete knows it doesn’t always cooperate. Once cement and water mix, the clock starts ticking.
