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.

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.

Is Steel Fiber Still the Best Choice for Your Project?
Steel fiber is widely used in steel fiber reinforced concrete, offering high strength and reliable structural reinforcement in slabs and industrial floors.
However, in real construction, its performance often depends heavily on mixing and placement. Issues such as fiber balling, uneven distribution, surface exposure, and potential corrosion can affect workability, finishing quality, and long-term durability.
Where Steel Fiber Can Slow Down Your Project
On site, steel fiber can increase handling effort, affect pumpability, and lead to inconsistent reinforcement if not properly dispersed.
Exposed fibers may also interfere with finishing, making it harder to achieve a smooth and uniform surface.

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.
