OKAYAMA GIKEN (Mining) Co., LTD., manufactures and export high-quality steel fibers for sprayed concrete in infrastructure, mining, and underground projects. we offer both technical support and reliable delivery timelines.
Our hooked-end steel fibers improve the ductility, crack resistance, and post-crack load-carrying capacity of sprayed concrete, offering a safer, longer-lasting solution for modern construction demands,reinforce your tunnel linings, mine walls, slopes, or underground structures with high-strength steel fibers specifically designed for shotcrete.
Increased Crack Control
Fibers distribute internal stress and minimize early-age shrinkage cracks.
Excellent Bonding with Cement Matrix
Hooked ends anchor firmly inside concrete, boosting tensile strength.
Improved Load Transfer
Enhanced toughness and impact resistance in dynamic environments.
No Need for Traditional Mesh Reinforcement
Reduces labor and installation time in tunnels or narrow sections.
Durable in Harsh Conditions
Performs well in underground, humid, or high-stress areas.
● Tunnel linings (subway, railway, highway)
● Mining shafts and galleries
● Slope stabilization
● Retaining walls
● Underground car parks and basements
● Hydroelectric projects
● Compatible with both dry-mix and wet-mix shotcrete methods.
