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

1. Available in various shapes: straight steel fibers, fluted steel fibers, wavy steel fibers, hooked steel fibers, bulbous steel fibers, double-pointed steel fibers, bundled steel fibers, and more.

2. Divided by cross-sectional shape, there are: circular, rectangular, slot-shaped, and irregular.

3. Divided by production process, there are: cut steel fiber (cut with fine steel wire); sheared steel fiber (cut with thin steel plate or strip steel).

Machined Steel Fiber (cut from thick steel plates or ingots); Melt-Drawn Steel Fiber (manufactured from molten steel).

4. Divided by material types:

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. Divided by surface coating status:

Uncoated, with an epoxy resin coating on the surface, galvanized, etc. In the industry, uncoated plain steel fibers are widely used.

6. Categorized by construction techniques, there are: spraying and casting types.

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.
