High-Performance Loose Hooked-End Steel Fiber | PIONEER®
Steel Fibre Reinforcement Solution for Durable Concrete
Enhance your concrete’s durability, crack control, and flexural strength with PIONEER® steel fibre reinforcement solutions engineered for modern infrastructure and industrial projects.
What Is PIONEER® Loose Hooked-End Steel Fibre?
PIONEER® PNE® ES-6660 loose hooked-end steel fibers are high-tensile steel fibre reinforcements designed to replace or reduce traditional rebar and welded mesh in steel fiber reinforced concrete (SFRC) and ultra-high-performance concrete (UHPC). Their precisely formed hooked ends provide superior anchorage and pull-out resistance, while the loose, tangle-free form ensures immediate, uniform dispersion during batching for reliable performance across industrial floors, shotcrete, pavements, and precast applications.
International Standards Compliance for Steel Fibre Reinforced Concrete
PIONEER® steel fibres comply with global standards to ensure consistent, reliable performance in steel fibre reinforced concrete:
-
ASTM A820 – Standard Specification for Steel Fibers for Concrete Reinforcement
-
ASTM C1116 – Standard Specification for Fiber-Reinforced Concrete and Shotcrete
-
EN 14889-1:2006 – Fibres for Concrete, Part 1: Steel Fibres

Key Benefits of Using Loose Hooked-End Steel Fibre in Concrete
Unlock advanced concrete performance and cost-efficiency with PIONEER® steel fibre reinforcement:
-
Superior Crack Control: Effectively manages plastic and drying shrinkage cracking in SFRC and UHPC.
-
Enhanced Flexural Strength: Increases post-crack load capacity, impact resistance, and fatigue durability.
-
Efficient Dispersion: Loose form ensures immediate, even distribution during batching without clumping.
-
Reduces Rebar and Mesh Use: Simplifies construction workflows while saving labor and material costs.
-
Durability in Harsh Environments: Corrosion-resistant steel fibres extend service life even under aggressive conditions.
-
Compatible with High-Performance Concrete: Ideal for SFRC, UHPC, and shotcrete requiring high tensile and flexural reinforcement.
Applications of Steel Fibre Reinforced Concrete
PIONEER® loose hooked-end steel fibres are suitable for a wide range of steel fibre reinforced concrete and shotcrete applications, including:
-
Industrial floors and heavy-duty warehouse slabs
-
Slab-on-ground and pavements requiring high toughness
-
Shotcrete for tunnels, slopes, and mining structures
-
Precast concrete pipes, panels, and tunnel segments
-
Bridge decks, overlays, and jointless floors
-
UHPC requiring advanced crack control and flexural strength

Usage Guidelines for Optimal Fibre Reinforcement
Achieve maximum performance in your SFRC and UHPC projects by following these guidelines:
-
Dosage: 15–45 kg/m³ depending on structural and durability requirements.
-
Mixing: Add fibres after aggregates and before water, mixing for 3–5 minutes to ensure full dispersion.
-
Placement: Compatible with pumping, casting, screeding, and vibration methods without specialised equipment.
-
Finishing: Standard concrete finishing tools can be used; minor fibre exposure does not affect long-term performance.
Custom Steel Fiber Packaging Options
To support streamlined logistics on your job sites, PIONEER® offers:
-
Water-Soluble Paper Bags (5 kg, 10 kg): For direct addition into mixers without unwrapping.
-
Cardboard Cartons: For organized site handling.
-
Bulk Options: Available on request for large projects.
