◆ 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.

Traditional concrete wall construction faces a long-standing set of operational challenges. Labor-intensive steel mesh installation consistently slows down project timelines. Over time, moisture penetration creates severe spalling risks as internal steel begins to corrode.
Traditional secondary reinforcement relies heavily on welded wire mesh. This approach demands significant manual labor. It frequently suffers from improper placement on job sites. Worse, it rarely prevents early-stage plastic shrinkage cracking.
Rising costs of heavily polymer-modified asphalt (PMA) and Stress Absorbing Membrane Interlayers (SAMI) are forcing pavement engineers to seek alternative mechanical reinforcement strategies.
Uncontrolled foam in industrial processes doesn't just look messy. It causes severe equipment cavitation and significantly reduces usable tank capacity. It also slows down production throughput and introduces critical defects into finished products.
Modern highway and industrial road construction faces massive pressure. Project owners demand aggressively accelerated timelines. They also expect extended lifecycle durability from every pavement slab.
Concrete contractors and specifying engineers face mounting operational challenges today. Unpredictable steel costs frequently squeeze tight project margins. Placing traditional welded wire mesh demands intensive manual labor and slows down pour schedules.
The concrete reinforcement industry is undergoing a massive shift. Engineers and contractors are rapidly moving away from labor-intensive traditional steel like rebar and wire mesh. Advanced engineered polymers now offer a smarter, highly efficient alternative for modern builds.
Managing foam generation remains a massive hurdle in food, beverage, and packaging production. Excess foam severely reduces processing throughput. It causes messy spillovers on facility floors. You must control this rapid macrofoam expansion without violating strict food-contact safety regulations.
