Crimped Steel Fiber for Fiber-Reinforced Concrete | PIONEER®
Durable, Cost-Effective Steel Fiber Reinforcement Solution
Enhance crack resistance, toughness, and load distribution with high-tensile crimped steel fibers engineered for SFRC .
Designed with a crimped / zigzag profile for stronger mechanical anchorage, these fibers provide reliable reinforcement for industrial floors, pavements, precast concrete, and shotcrete applications.
What Are PIONEER® Crimped Steel Fibres?
PNE® CS-4025 crimped steel fibres are cold-drawn, high-strength fibers designed to reinforce concrete by reducing early-age shrinkage cracking, improving ductility, and enhancing post-crack load-carrying capacity.
The crimped (zigzag/wavy/deformed) geometry increases pull-out resistance and provides three-dimensional reinforcement, making the fibers suitable for:
-
Industrial flooring & pavement slabs
-
Precast elements & composite decks
-
Shotcrete for tunnels & underground structures
-
UHPC requiring high toughness
Compared with traditional welded wire mesh, crimped fibers help reduce labor cost, improve uniform dispersion, and enhance structural durability.

Usage Guidelines for Steel Fibre Reinforced Concrete
Follow these recommendations to maximize the performance of crimped steel fibres in your concrete:
-
Dosage Recommendation: 15–45 kg/m³ depending on load demands, slab thickness, and crack control requirements.
-
Mixing Instruction: Add fibers after aggregates, mix 3–5 minutes to ensure uniform dispersion and avoid balling.
-
Placement: Fully compatible with pumping, casting, screeding, and vibrating.
-
Finishing: Standard tools apply; minor fiber exposure does not affect structural performance.

FAQ
Yes. Crimped steel fibers are fully compatible with water reducers, superplasticizers, accelerators, and most concrete admixtures. Proper mixing order—typically adding fibers after aggregates—ensures stable workability.
Not significantly. When properly mixed and placed, most fibers remain below the finished surface. For exposed architectural surfaces, adjustments to mix design and finishing tools can ensure a smooth, fiber-free appearance.
Engineers often reference ASTM C1609, EN 14651, and JSCE SF testing methods to evaluate flexural toughness, residual strength, and post-crack behavior of fiber-reinforced concrete.
In many light-to-medium duty applications—such as industrial floors, pavements, precast elements, and shotcrete—crimped steel fibers can partially or fully replace welded wire mesh, reducing labor and improving crack control.
Crimped steel fibers should be kept in dry, covered spaces to prevent moisture exposure. Although minor rust does not impact performance, proper storage ensures clean dosing and consistent batching efficiency.
