For the selection of steel fiber in the construction industry general low carbon steel cold cut steel fiber, with 

no need to add anti rust agent, preservative and other advantages, and can improve the performance of 

prefabricated 26 times, can replace or reduce the dosage of reinforcing steel barreinforced type, shorten 

production time, improve the degree of mechanization construction, than ordinary construction method can

not achieve the effect, such as inhibition of roof crack, culvertWater Leakage etc.. Steel fiber used in highway 

surface bridge, cement sleepers, explosion-proofwarehouse, nuclear test field, the rocket launching site precast concrete component of stress.Tunnel 

kiln mesa, power plant boiler flue, and other serious sudden cold and heat, the use ofrefractory lining and 

prefabricated parts mechanical function of impact crack easily grinding conditions.
