Product Overview

Glued Hooked-End Steel Fibers are high-performance reinforcement materials manufactured from premium cold-drawn steel wire, specifically engineered with an exceptional tensile strength of 1100-1800MPa to ensure superior structural integrity. These fibers are designed to achieve uniform distribution within the cement matrix, providing high bonding strength that significantly enhances the crack resistance, fracture toughness, and shear strength of concrete. Ideal for heavy-duty applications such as highway pavements, bridges, tunnels, and industrial flooring, our Glued Hooked-End Steel Fibers deliver outstanding durability, fatigue resistance, and post-crack ductility for the most demanding construction projects.

Glued Hooked-End Steel Fibers are precision-engineered reinforcement solutions manufactured from high-quality cold-drawn wire, specifically designed to meet the rigorous demands of industrial concrete projects. Featuring a versatile range of models including ZDM 80/60, ZDM 75/60, and ZDM 46/35, these fibers offer customized performance with tensile strengths ranging from 1100MPa to 1800MPa. The advanced glued bundle technology ensures that each fiber is uniformly dispersed during the mixing process, creating a high-strength 3D reinforcement network within the cement matrix.

Our Glued Hooked-End Steel Fibers are optimized to provide exceptional aspect ratios (up to 80 L/D), significantly improving the concrete’s post-crack ductility, impact resistance, and fatigue life. Whether applied in heavy-duty industrial flooring, tunnel linings, or bridge engineering, these fibers effectively bridge micro-cracks and prevent structural failure. By choosing ZDM’s specialized steel fibers, you ensure long-term durability and superior mechanical performance for highway pavements, airport runways, and complex hydraulic structures.

Product Advantages

• Excellent Crack Control
• High Flexural Strength
• Improved Load-Bearing Capacity
• Uniform Dispersion
• Enhanced Durability

Excellent Crack Control The hooked ends provide an exceptional mechanical anchorage within the cement matrix. This unique structure effectively bridges micro-cracks from the initial stage, preventing them from propagating into major structural fissures and ensuring long-term integrity.

High Flexural Strength By incorporating Glued Hooked-End Steel Fibers, the flexural performance of concrete is significantly improved. This allows for thinner slab designs without compromising on safety, making it a cost-effective solution for high-performance concrete (HPC) projects.

Improved Load-Bearing Capacity The high tensile strength (up to 1800MPa) of our fibers distributes stress more evenly across the structure. This leads to a substantial increase in the concrete’s ability to handle heavy dynamic and static loads, which is essential for industrial floors and bridge decks.

Uniform Dispersion (Glued Technology) The “Glued” bundle technology prevents the fibers from “balling” during the mixing process. As the concrete is mixed, the glue dissolves, allowing each individual fiber to disperse uniformly throughout the entire batch, creating a consistent 3D reinforcement network.

Enhanced Durability Our fibers provide outstanding resistance to impact, fatigue, and abrasion. By enhancing the overall toughness of the concrete, you reduce maintenance costs and extend the service life of infrastructure in harsh environments like tunnels and hydraulic engineering.

Frequently Asked Questions about Glued Hooked-End Steel Fibers

Q1: What are the main applications of Glued Hooked-End Steel Fibers? A: Glued Hooked-End Steel Fibers are primarily used in heavy-duty industrial flooring, tunnel shotcrete, bridge decks, and high-performance precast concrete elements. Their unique hooked ends provide superior mechanical anchorage, making them ideal for projects requiring high impact and crack resistance.

Q2: Why is the “Glued” feature important for steel fibers? A: The “Glued” bundle technology prevents the fibers from “balling” or clumping during the mixing process. As the concrete is mixed, the environmentally friendly glue dissolves, allowing each Glued Hooked-End Steel Fiber to disperse uniformly throughout the entire batch, creating a consistent 3D reinforcement network.

Q3: Can I combine these fibers with other reinforcement materials? A: Yes. Many engineers use Glued Hooked-End Steel Fibers in conjunction with traditional rebar or our [Copper Coated Micro Steel Fiber] to achieve a hybrid reinforcement effect, balancing macro-crack control with micro-crack prevention for maximum durability.
