Coated Micro Steel Fiber for Concrete Reinforcement | PIONEER®
Advanced Copper-Coated Micro Steel Fiber for UHPC and SFRC

Upgrade your concrete reinforcement with UHPC copper-coated micro steel fibre that delivers long-term durability in high-speed rail, bridges, tunnels, and architectural structures.

What Are Copper-Coated Micro Steel Fibres?

PIONEER® PNE® MS-6013 Copper-coated micro steel fibres, also referred to as micro steel fiber, brass micro steel fibre, or copper-plated micro fiber, are high-tensile fibers engineered to improve post-crack performance, ductility, and crack bridging in ultra-high-performance concrete (UHPC), steel fibre reinforced concrete (SFRC), and powder concrete.

Cuts Rebar Requirements

Reduces Rrack Propagation

PNE® MS-6013 micro steel fiber reduces crack propagation and cuts rebar requirements in reinforced concrete structures.

International Standards for Micro Steel Fibre Reinforced Concrete

PIONEER® micro steel fibres comply with leading global standards for fibre-reinforced concrete:

  • ASTM A820 – Standard Specification for Steel Fibers for Concrete Reinforcement

  • ASTM C1116 – Standard Specification for Fiber-Reinforced Concrete

  • EN 14889-1: Steel Fibres for Concrete – Definitions, Specifications, and Conformity (Europe)

​These standards ensure consistent quality and performance in your UHPC and SFRC projects.

Key Benefits of Using Micro Steel Fibre in UHPC

Using copper-coated micro steel fibre reinforcement in UHPC and high-performance concrete offers:

  • High Tensile Strength: >2,500 MPa for exceptional crack control and toughness.

  • Corrosion Resistance: Copper coating resists corrosion in harsh conditions.

  • Efficient Crack Control: Fine fibres distribute uniformly for effective bridging.

  • Lightweight and Efficient: Supports thinner, lighter concrete designs without compromising strength.

  • Enhanced Post-Crack Load Capacity: Improves structural integrity in UHPC and SFRC.

Applications of Micro Steel Fibre in UHPC and Powder Concrete

Copper-coated micro steel fibres are widely used in:

  • High-Speed Rail Infrastructure: UHPC track slabs and joints for crack control and durability.

  • UHPC Bridges and Long-Span Structures: Enhanced flexural strength and impact resistance.

  • Tunnels and Underground Construction: Shotcrete and precast segments for ductility.

  • Powder Concrete Overlays: Ultra-thin overlays for structural repair and rehabilitation.

  • Precast UHPC Elements: Panels, façade components, and slim elements needing high strength.

  • Industrial Floors and Heavy-Use Pavements: Increased impact resistance under heavy loads.

  • Protective and Security Structures: Blast and impact resistance in UHPC barriers.

  • Bridge Decks and Overlays: Superior crack resistance and lifespan extension.

These fibres are ideal for SFRC, UHPC, powder concrete, and all advanced concrete systems where toughness and durability are critical.

How to Use Copper-Coated Micro Steel Fibre for Concrete

For optimal results with UHPC copper-coated micro steel fibre:

  • Dosage: 156–314 kg/m³, adjusted to design and project requirements.

  • Batching: Add fibres gradually during dry mixing for even distribution.

  • Mixing: Extend mixing time to prevent clumping.

  • Placement: Compatible with standard UHPC casting and finishing methods.

  • Finishing: Slight fibre visibility may occur but does not affect durability or performance.

FAQ

  • Copper-coated micro steel fiber is a high-tensile, fine-diameter steel fiber with a copper or brass surface coating. It is designed to enhance crack control, post-crack strength, and ductility in UHPC, SFRC, and powder-based concrete systems.

  • PNE® MS-6013 is commonly used in ultra-high-performance concrete (UHPC), reactive powder concrete (RPC), precast elements, thin-section concrete, and other applications where micro crack control and tensile performance are critical.

  • The copper coating improves corrosion resistance, enhances fiber dispersion during mixing, and increases bond performance between the fiber and the cement matrix, especially in dense or low-water concrete mixes.

  • Micro steel fibers help bridge micro-cracks, delay crack propagation, and improve post-crack load-bearing capacity. This results in higher toughness, improved ductility, and better durability compared to plain concrete.
