Loose hook-end steel fibre intercept micro-crack expansion Loose hooked end steel fiberCold-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 can be fully dispersed and cracking propagation be effectively controlled. Unlike conventional reinforced fiber, steel fibers focus on three dimentional reinforcement and make it impossible for plain crack to follow. How hook-end steel fibre benefit you? Substantially enhance initial crack strength; Continuously provide post-crack strength; Increase speed of construction; Stronger joints lower the possibility of maintenance. Save MONEY and time.
