Round crimped steel fiber is a new type of reinforced fiber. It is fabricated by cold-drawn low carbon steel wire which conforming to EN 4889-1 Type 1 and ASTM A820/A820M-04 Type 1. Corrugated profile adds pull-out resistance compared with rebar, which is increasingly replaced by steel fibers.
When fully annealed, melt extract stainless steel fibers are more pliable and ductile. They not only allow for more user-friendly than the stiff cut fibers, but also have better flow features. It is especially characterized by thermal shock resistance, steep thermal gradients resistance and mechanic
Glued steel fiber refers to loose hooked end fibres glued together in a row way (shown as below figure). The big difference between loose and glued fibers is that the former is easy to block together and the latter is easy to disperse uniformly.
Cold-drawn hooked end steel fiber is manufactured by quality base steel bar, which has excellent mechanical properties including high tensile strength. Hence, the average tensile strength of the reinforced fibre surpasses 1100 MPa. Owing to high strength and uniform distribution of fibers, stresses
Flat end steel fibers are cold-drawn steel fibers with high tensile strength up to 1150 MPa. Special design of flat end provides optimum anchorage within the concrete mix rather than relying on the friction between concrete and steel. Flattened end steel fibres are ideal for shotcrete and precast ap
Flat crimped steel fiber are manufactured by milling steel ingots. Compated with other steel fibers, its tensile strength is a little lower, about 600 Mpa. To achieve the same performance, the percentage of steel fibers should increases.
