Crimped Steel Fiber for Fiber-Reinforced Concrete | PIONEER®
Durable, Cost-Effective Steel Fiber Reinforcement Solution
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.

Applicable standards and test methods
PIONEER® steel fibers are developed with reference to internationally recognized standards for steel fiber products and fiber-reinforced concrete. Applicable standards and documentation depend on the product grade, intended application, project requirements, and destination market.
-
ASTM A820/A820M — Standard Specification for Steel Fibers for Fiber-Reinforced Concrete
-
ASTM C1116/C1116M — Standard Specification for Fiber-Reinforced Concrete
-
EN 14889-1:2006 — Fibres for Concrete — Part 1: Steel Fibres — Definitions, Specifications and Conformity
These standards provide technical references for steel fiber selection and use in precast concrete, industrial floors, shotcrete, and other fiber-reinforced concrete applications. Product suitability should be confirmed according to the project design, required performance, and applicable local regulations.

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
PNE® CS-4025 is a crimped steel fiber for fiber-reinforced concrete. Its mechanically deformed profile distinguishes it from hooked-end and corrugated steel fiber products.
The crimped profile creates multiple mechanical-interaction points between the steel fiber and the surrounding concrete matrix. When cracks develop, fibers crossing the crack plane can contribute to crack bridging and post-crack load transfer.
Final dosage should follow the current PNE® CS-4025 TDS and should be selected according to the concrete application, required performance, applicable test method and project design.
It can be evaluated in concrete mixes containing common admixtures, but compatibility should be confirmed for the specific mix design, fiber dosage, workability target and batching procedure.
It may be considered in selected applications where project design, performance testing and applicable approvals support substitution or reduction of conventional reinforcement. It is not a universal replacement.
