| Parameter | Specification |
|---|---|
| Dimensions (L×Φ) | 20-60 mm × 0.3-1.2 mm |
| Aspect Ratio | 20-100 |
| Tensile Strength | ≥600 MPa |
| Buckling Resistance | ≥3 cycles |
| Surface Profile | Anchoring ends with micro-texturing (h=1.5-2.0mm) |
Notes:
1.Fiber count per kg calculated using nominal dimensions (steel density: 7.85 g/cm³).
2. dimensions and coatings available.
High anchorage — milled ends with rough texture for superior bond and crack resistance.
Good dispersion — uniform shape, no clumping, easy mixing and placement.
High impact & wear resistance — suppresses microcracks; ideal for roads, floors, tunnels.
Cost-effective production — consistent sizes, cheaper than stainless or shear-wave fibers.
| Dimensions (Length × Diameter) | L/D | Dispersion | Features & Applications |
| 20mm×0.6mm | 33.33 | PERFECT | Non-clumping, low rebound — ideal for shotcrete, thin-walled elements and pumping. |
| 25mm×0.7mm | 35.71 | PERFECT | Standard grade — floors, repairs, conventional pavements; highest construction compatibility. |
| 30mm×0.8mm | 37.5 | VERY GOOD | Main market sizes — suitable for cast-in-place, precast, and highway pavements. |
| 32mm×0.8mm | 40.00 | GOOD | Heavy-duty floors and bridge decks — mixes fine with normal mixing; pay attention at high dosages. |
| 35mm×0.9mm | 38.89 | GOOD | Erosion/abrasion resistance and structural strengthening — not recommended for long-distance pumping. |
| 40mm×0.9mm | 44.44 | GENERAL | Prone to slight clumping — suitable only for hand mixing / localized casting; pumping prohibited. |
1.Q:How to ensure uniform dispersion of fibers in concrete?
A:Use forced-action mixers, add fibers in stages, prepare a good paste first, avoid tossing in fiber mats, follow manufacturer mixing
times, and inspect samples.
2.Q:Will milled fibers affect slump and pumpability? How to improve?
A:High dosages reduce slump and may affect pumpability. Improve with PCE superplasticizers, viscosity modifiers, optimized
aggregate grading, staged fiber addition and longer mixing.
3.Q: What performance can milled steel fiber improve for concrete?
A: It greatly enhances concrete crack resistance, impact resistance, wear resistance, impermeability and fatigue resistance.
4.Q:What are packaging, MOQ and lead time?
A:Common packaging: 25kg bags/boxes, bulk or big bags; MOQ depends on supplier (samples to tons); lead time typically 7–15 days depending on stock and order size.
