Why Use Metal Fiber?

Steel fiber reinforced concrete is a revolutionary composite material that dramatically improves structural performance across multiple dimensions.

Increased Strength

Steel fiber concrete significantly enhances compressive, tensile, and flexural strength compared to conventional concrete.

Enhanced Toughness

Improves impact strength, crack resistance, and fatigue endurance—ideal for high-stress environments.

Thermal Stability

Refractory steel fibers improve resistance to thermal cycling, corrosion, and abrasion in extreme heat.

Durability & Longevity

Extends service life of concrete and refractory structures, reducing maintenance and replacement costs.

Seismic Resistance

Ideal for earthquake-prone regions due to enhanced ductility and energy absorption capacity.

Easy Integration

Simple mixing process: add fibers during batching to ensure uniform dispersion in concrete or refractory matrix.

Frequently Asked Questions

What is the correct way to mix steel fiber into concrete?

1. Add sand and gravel to the hopper.
2. Mix briefly, then add steel fibers uniformly (preferably on top of stones).
3. Add cement and mix for ~2 minutes.
4. Add water and mix for another 2 minutes.
5. Transport and place immediately. Proper dispersion ensures optimal performance.

Where are refractory steel fibers typically used?

In high-temperature environments such as steel mills, non-ferrous smelting, kilns, incinerators, and nuclear containment systems where thermal shock resistance is critical.

What are the advantages of melt-extracted stainless steel fibers?

They feature a microcrystalline structure, high strength, natural rough surface, and excellent high-temperature corrosion resistance—ideal for refractory enhancement.

Can polypropylene fibers replace steel fibers?

No—they serve different purposes. PP fibers control plastic shrinkage cracking, while steel fibers enhance structural strength and toughness. They can be used together.

Do you offer custom fiber specifications?

Yes. We manufacture to client specifications including length, diameter, aspect ratio, and coating requirements for both steel and synthetic fibers.
