Types and characteristic parameters of steel fibers

According to the material, steel fiber can be divided into ordinary carbon steel fiber and stainless steel fiber. Among them, ordinary steel fiber is the most used; according to the shape, it can be divided into long straight shape, indentation shape, wavy shape, hook shape, big head shape and twisted shape; According to the cross-sectional shape, it is divided into round, rectangular, crescent and irregular shapes; according to the production process, it is divided into cutting type, shearing type, milling type and melting type; according to the construction purpose, it is divided into pouring steel fiber and spraying steel fiber.
In order to meet the reinforcement effect and construction performance of steel fiber, the length of steel fiber is usually 15~60mm, the diameter or equivalent diameter is 0.3~1.2mm, the aspect ratio is 30~100, and the volume content of the fiber is 0.5%~2 %.
