OKAYAMA GIKEN (Mining) Co., LTD., is a manufacturer and exporter of Steel wire fiber with competitive price ,fast delivery ,our steel fibers are specially designed for reinforcement in refractory castables, shotcrete, and concrete. With consistent dimensions, excellent tensile strength, and clean surface finish, they improve crack resistance, enhance thermal shock stability, and extend the life of your installations.whether you're working on a tunnel lining, industrial flooring, or high-temperature furnace, our steel fibers are the smart, cost-effective solution for structural durability.
Steel wire fiber is a steel wire-based reinforcement material that is widely used in multiple industrial fields, especially in the construction, metallurgy and refractory industries. Steel wire fiber does not replace traditional raw materials, but plays an extremely important "enhancement role" in structural durability and engineering life in a "small addition brings big improvement" way.
Compared with castables, the application of spray coatings in the refractory industry, steel wire fiber has many advantages:
1. Provide mechanical reinforcement. crack control. and improve thermal shock resistance
2. Actively improve the toughness and strength of the overall structure
3. Relieve cracking during drying and heating. increase service life.
4. Reduce the risk of bursting and peeling
5. Can be directly mixed into concrete. reduce construction procedures. save labor and construction time
6. Can be "synergistically reinforced" with steel bars
7. Precise measurement. almost no waste
8. Flexibly adapt to various structures. suitable for special processes such as shotcrete
1. Refractory industry
Liners of electric arc furnaces, ladles and tundishes in steel plants
Liners of high-temperature equipment such as cement rotary kilns and incinerators
Parts with heavy mechanical vibration or frequent thermal shock
After adding steel fiber, the service life of refractory materials is significantly extended, there are fewer cracks after construction, and the ability to resist mechanical impact is enhanced.
2. Construction industry (especially industrial flooring)
Industrial floors (Warehouse floors)
Airport runways
Tunnel linings
Port and dock concrete structures
Steel wire fibers are evenly distributed in concrete and can replace traditional steel bars to improve the crack resistance, impact resistance and durability of concrete.
✅ Especially suitable for:
Concrete floors that are required to bear heavy objects
Structures affected by dynamic loads, thermal expansion and contraction
3. Shotcrete
Tunnel support
Mining support
Subway/underground passage structure
steel wire fiber reinforced shotcrete can significantly reduce concrete rebound, improve early strength and overall toughness, and is widely used in underground engineering support systems.
4. Special uses
Railway sleepers
Bridge deck concrete
High temperature kiln lining (combined with refractory materials)
