Steel fiber refers to fibers with an aspect ratio of 40-80 produced by cutting fine steel wires, shearing cold-rolled strips, milling steel ingots, or rapid cooling of molten steel. It is an industrial material used to strengthen concrete. Adding fiber to concrete is a common practice to improve its strength, durability, and performance
Hooked Ends Steel Fibers are microscopic strands of steel, used to reinforce and strengthen concrete structures. A Hooked End Steel Fiber is made up of 100% steel wire and features a hooked end that enhances bonding with the concrete matrix. This design increases the bond strength between the fiber and concrete matrix resulting in improved mechanical properties.
Hooked End Glued Steel Fiber is a low carbon, cold-drawn and hooked-end steel wire fiber designed to provide concrete with temperature and shrinkage crack control, enhanced flexural reinforcement, improved shear strength and increase the crack resistance of concrete.
The fiber can be loosed or glued, 2types.
Hooked End Glued Steel Fiber complies with ASTM C1116, and EN14889-1
Glued hooked steel fiber is a high-performance composite material used for concrete reinforcement. It is a prefabricated reinforcement material formed by bonding rows of hooked steel fibers together with a water-soluble adhesive.
Cut steel fibers, produced using cold drawing technology below the metal crystal temperature with low-carbon alloy as the base material, can achieve tensile strengths of 1150-3000 MPa.
Steel fiber is a new type of composite material widely used in construction, road, bridge, and other engineering fields.
The metal steel fiber shotcrete replaces the hanging net construction, which not only saves the cost of hanging nets, but also reduces the risk of rockfall injury.
Application field:
1.Highway bridge
2.Hydraulic dam
3. Railway sleepers
4.Port and Ocean Engineering
5.Tunnel and mine engineering
6.Pipeline engineering
7.Other construction projects
Copper micro steel fiber is a type of steel fiber that is coated with copper to improve its electrical and thermal conductivity. These fibers are generally used in concrete to increase its strength and durability. The copper coating on the steel fibers enhances the bonding between the fiber and the concrete matrix, thereby improving the overall toughness and ductility of the concrete. Copper micro steel fiber is also known as copper coated steel fiber or copper clad steel fiber.
Steel fiber is a high-performance concrete reinforcement material with a high aspect ratio, widely used to enhance the mechanical properties of concrete structures.
Diameter: Typically 0.1–1.5 mm, with common values of 0.55 mm, 0.75 mm, 0.9 mm, and 1.0 mm.
Length: Ranges from 10–60 mm, commonly 25 mm, 30 mm, 40 mm, and 60 mm for engineering applications.
Aspect Ratio (Length/Diameter): 40–80, a key parameter for reinforcement effectiveness (50–60 is most widely used).
Tensile Strength: 1000–2100 MPa, with high-strength grades exceeding 1500 MPa.
Surface Treatment: Uncoated, epoxy-coated, or galvanized (to improve corrosion resistance).
Packaging: 20 kg/bag, 1000–1200 kg/pallet (standard industrial packaging).
