Loose Hooked End Steel Fiber

SDS Loose Hooked End Steel Fiber

Hooked end steel fibres are made of high-quality cold drawn steel line, in order to make sure that it has high tensile strength and animal tolerance. And the steel fiber in bulk ensures the mixing fast and convenient, and the distribution homogeneous. During pulling from the cement, the steel fiber hooked end is deformation slowly it is considered to be the best anchorage force.


Unlike conventional reinforced fiber, steel fibers focus on three-dimensional reinforcement and make it impossible for a plain crack to follow.


Advantages of Loose Hooked End Steel Fiber

  • Technology Advantage
    Technology Advantage

    The design of end hooks at both ends of steel fiber is the best anchoring design, which slowly deforms in the process of drawing, thus enhancing the binding force between hooked steel fiber and concrete.

  • Material Advantage
    Material Advantage

    SDS hooked end steel fibre is made of high-quality wire by cold drawing, and its tensile strength is greater than 1100MPa, which ensures extremely small tolerance and high tensile strength.

  • Economic Advantage
    Economic Advantage

    A. Compared with ordinary concrete, the same mixing and construction, do not need to add equipment.

    B. Under the same strength, the concrete consumption can be saved.

    C. Replace or partially replace reinforcement.

    D. Shorten the construction period, especially suitable for large projects requiring continuous and rapid pouring of concrete.

FAQs of Loose Hooked End Steel Fiber

  • Loose hooked end steel fiber is individually dispersed in concrete, while glued fibers are bundled together with water-soluble adhesive for faster batching. Loose fibers provide more uniform distribution, better crack control, and easier adjustment of dosage in high-performance concrete applications. Many contractors prefer loose hooked end steel fiber for precast concrete, industrial flooring, tunnel lining, and steel fibers for shotcrete because it improves reinforcement efficiency and reduces fiber balling when properly mixed. A professional steel fiber manufacturer can recommend the best option based on concrete mix design and project requirements.


    What is the difference between glued and loose hooked end steel fiber?
  • Loose hooked end steel fiber enhances concrete toughness, impact resistance, crack control, and post-crack load capacity. The hooked ends improve anchorage inside the concrete matrix, helping distribute stress more effectively than straight fibers. These concrete fiber solutions are widely used in slabs, warehouses, pavements, mining tunnels, and steel fibers for shotcrete applications where durability and structural performance are critical.


    Why use loose hooked end steel fiber in concrete reinforcement?
  • Typical dosage ranges from 20–80 kg/m³ depending on the application, structural requirements, and concrete grade. Steel fiber for industrial floors and pavements often use moderate dosages, while steel fibers for shotcrete and heavy-duty infrastructure may require higher fiber content for enhanced toughness and crack resistance. Professional concrete fiber solutions suppliers usually recommend dosage based on load conditions and performance standards.


    How much loose hooked end steel fiber should be added to concrete?

Loose Hooked End Steel Fiber Projects

  • Loose Hooked End Steel Fiber for Logistics and Storage
    Loose Hooked End Steel Fiber for Logistics and Storage

    A total of 500 tons of loose hooked end steel fibers (0.70mm diameter × 50mm length) were prepared for international delivery and warehouse storage. The products were carefully packed to maintain consistent performance and safe transportation for overseas construction projects.


    The steel fibers help enhance early crack resistance and provide continuous structural reinforcement after cracking. They are widely used to improve construction speed, strengthen concrete joints, and reduce long-term maintenance requirements while saving both labor and project costs. CE-certified quality standards are supported.


  • Loose Hooked End Steel Fiber for Shotcrete
    Loose Hooked End Steel Fiber for Shotcrete

    This project used loose hooked end steel fiber with a diameter of 0.55mm and a length of 30mm for shotcrete reinforcement applications. The steel fibers are widely used in building, bridge, and hydraulic engineering repair projects, helping improve crack resistance, structural strength, and bonding performance. They are suitable for reinforcing concrete slabs, beams, piers, dam surfaces, masonry structures, aqueducts, and underground waterproofing systems, while also enhancing seepage control, durability, and long-term maintenance performance.
