Hooked end bundled steel fibers are bonded together with water-soluble glue, featuring strong anchoring force with hooked ends. They disperse evenly automatically during mixing, effectively enhancing concrete crack resistance, flexural strength and impact resistance, widely used in floors, bridges, tunnels and shotcrete
High-Purity Material Selection: To ensure the strength and ductility of the steel fiber, we use custom-made, high-quality low-carbon steel wire rod with a purity exceeding 99.5%.
Strong Anchorage: The steel fiber end hooks are specially designed to match different concrete types and application scenarios.
High Strength: The steel fiber strength reaches 1000-2300 MPa, 2-3 times that of ordinary rebar.
High Aspect Ratio: The high aspect ratio ensures the effectiveness of the steel fiber.
High-Quality Glue: High-quality water-soluble glue ensures uniform dispersion of the steel fiber in the concrete without clumping.
Excellent Dispersion: During the concrete mixing process, the steel fiber undergoes a secondary dispersion process, during which the water-soluble glue begins to dissolve. The rows of steel fibers, after their primary dispersion, are then redispersed into single steel fibers in each corner, forming a three-dimensional fiber network within the concrete, providing comprehensive reinforcement.

Hooked end bundled steel fibers are widely applied in highway pavements, bridge deck paving, tunnel shotcrete, mine roadway support, water conservancy projects, port terminals, airport runways, heavy-duty industrial floors, civil defense projects, precast concrete components, building reinforcement, culverts and slope protection. It greatly improves crack resistance, impact resistance, fatigue resistance, wear resistance and impermeability of concrete, and extends the service life of building structures.
