Hooked End Steel Fiber Improves Impact-Resistant & Bearing Capacity

Some durable hooked end steel fibers.

Hooked end steel fiber is a part in building construction, floor pavement and tunnelling project.

Hooked end steel fiber is manufactured by quality base steel bar, characterized by high tensile strength. Thus, the average tensile strength of the steel fiber surpasses 1100 MPa. Owing to its 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 dimensional reinforcement and make it impossible for plain crack to follow.

Hooked end steel fiber used in various places, such as highway pavement, tunnel project, hydropower station, etc.
