At OKAYAMA GIKEN (Mining) Co., LTD., we produce high-strength Steel Fibers For Concrete Reinforcement engineered to reinforce concrete and enhance durability under extreme conditions. Our Steel Fiber is crafted for optimal performance, providing exceptional crack resistance and structural integrity in demanding applications such as tunnels, bridges, and industrial floors. Built to meet the highest standards, our Steel Fiber ensures long-lasting support, making it the trusted choice for projects that demand strength and resilience.
Our high-performance steel fibers for concrete reinforcement are engineered to enhance flexural strength, control shrinkage cracking, and increase concrete toughness in construction applications.Ideal for use in industrial floors, pavements, precast elements, tunnel linings, shotcrete, and foundations.
High Tensile Strength: ≥1100 MPa
Perfect for heavy-load and impact-resistance concrete applications.
Enhanced Crack Control:
Minimizes plastic shrinkage and thermal cracks in slabs and walls.
Uniform Mixing:
No clumping or balling during batching; easy to mix with standard equipment.
Improved Load Transfer:
Works as micro reinforcement to distribute load and stress uniformly.
No Need for Traditional Rebar in Some Cases:
Saves time and labor on-site.
● Electric Arc Furnace (EAF) walls and roofs
● Steel ladle & tundish lining castables
● Precast refractory blocks
● Cement rotary kiln linings
● Garbage incinerator lining
● Boilers and industrial furnaces
● Hooked-end steel fibers provide mechanical anchorage in the cement matrix, significantly improving post-crack performance and ductility.
