End-hooked steel fibers achieve mechanical anchoring through hooks at both ends, providing strong anchoring force. They are widely suitable for normal to medium-high strength concrete structures and offer high cost-effectiveness, making them the most common type in engineering.

Milled steel fibers have a rough surface and bond firmly to the matrix, offering excellent crack resistance and shear resistance. They are suitable for locations with high impact and shear resistance requirements, such as bridges and dams. Copper-plated micro-wires have extremely high strength, small diameters, and a large number of fibers. They are mainly used in ultra-high performance concrete such as UHPC and RPC, endowing the material with ultra-high toughness and durability. In actual selection, structural stress characteristics, construction conditions, and cost budget should be comprehensively weighed.
