Steel Fibers For Crack Control
Why we use steel fiber for cracking control?

The steel fiber has a high tensile strength of 1000Mpa, which could ensure that the steel fiber will not be broken when working with concrete;

The end hooks at both ends of steel fibre supplier ensure the best anchor between steel fiber and concrete solid so that steel fiber can effectively transmit and distribute stress, which can effectively control the development of cracks in concrete.
