Steel Fiber refers to the fiber whose diameter ratio (the ratio of fiber length to diameter, when the fiber section is non-circular, the diameter of equivalent section circle area is used) is 40 ~ 80 by cutting fine steel wire, cutting cold rolled strip steel, ingot milling or rapid condensation of molten steel.
The properties of steel fibers produced by different methods are also different.Although steel fiber came out soon, it has been more and more widely used and more kinds.
