Steel fiber manufacturer

Micro steel fiber is a fiber material used to reinforce concrete and other composite materials. They are typically made of fine steel wires with high aspect ratios and small dimensions. Micro steel fibers have lengths ranging from 10 to 30 millimeters and diameters ranging from 0.2 to 0.5 millimeters.

Micro steel fiberAdvantages

1. Unmatched Strength & Durability

   • Ultra-High Tensile Strength: >2850 MPa ensures superior crack resistance and load-bearing capacity.

   • Elastic Modulus of 200 GPa: Maintains structural integrity under extreme stress and high-temperature conditions (ideal for tunnels, mines, and industrial flooring).

   • Brass-Coated Surface: Enhances bonding with concrete matrix while resisting corrosion in humid/underground environments.

2. Precision Customization

   • Flexible Dimensions: Diameter 0.12-0.3mm (±0.02mm) | Length 6-60mm (±1mm) – tailored to your project requirements.

   • Optimized Aspect Ratio: Scientifically calibrated length/diameter ratios maximize dispersion and reinforcement efficiency.

3. Cost-Effective Reinforcement

   • 30% Savings vs. Rebar: Reduce material costs and labor time with lightweight, easy-to-mix fibers.

   • Long-Term ROI: Minimize maintenance costs through enhanced concrete lifespan and crack prevention.

4. Safety & Compliance

   • Non-Toxic & Eco-Friendly: Meets ASTM A820 and EN 14889-1 standards for construction safety.

   • Fire Resistance: Withstands temperatures up to 800°C, suitable for fireproofing applications.

DAYE Copper/Brass Coated steel fiber is a special metal fiber with strong compression, tension and crack resistance. anti crack concrete fibers is widely used in high-speed railway prefabricated parts, RPC cover panels, UHPC prefabricated parts and other important engineering components.

Micro Steel Fiber Technical Parameters:

Economic Advantage：

• 1. Steel fiber costs less

• 2．Concrete consumption can be reduced by 30% ~ 50% under the same strength;.

• 3．Rebar partially or completely no needed anymore, or reduce the diameter of steel bar for1~2mm;

• 4．Construction cycle shortened by 25%, suitable for projects where continuous and fast concrete placing is required;

• 5. Mixing as conventional concrete, no extra equipment needed.

Main Applications:

• Underground Construction: Tunnels, subway systems, basements.

• High-Temperature Zones: Foundry floors, kiln foundations, chimneys.

• Industrial & Civil Engineering: Bridges, highways, precast elements, shotcrete.
