Steel fibers have a relatively short history, but their application fields are expanding widely. Correspondingly, the variety of steel fibers is also increasing continuously.

1. Available in various shapes, including straight, ribbed, wavy, hooked, headed, double-pointed, and bundled steel fibers, among others.

2. Divided by cross-sectional shape, they include: round, rectangular,槽型, irregular.

3. By production process, there are: cut steel fiber (using fine steel wire to cut); sheared steel fiber (using thin steel plate or strip to shear).

Machined steel fiber (cut from thick steel plates or ingots); Molten drawn steel fiber (manufactured from molten steel).

4. Divided by material:

Plain carbon steel fiber (tensile strength typically ranges from 300 to 2500 MPa).

Stainless Steel Fibers (including grades 304, 310, 330, 430, 446, etc.)

Other metal fibers (aluminum, copper, titanium, and alloy fibers). 5. Categorized by surface coating status:

Uncoated, surface coated with epoxy resin, galvanized, etc. The commonly used in the industry is uncoated plain steel fiber.

6. Categorized by construction techniques, there are: jetted and cast.

7. Classified by diameter size:

Standard steel fibers (diameter d > 0.08mm)

Ultra-fine steel fibers (diameter d≤0.08mm)

Ultra-fine steel fibers are primarily used to reinforce plastics and asbestos friction materials.
