Fibers for concrete is a new composite materials that is one of the fastest growing products and the most extensive application. The specification of concrete will be changed after mixing into a little fibers, this is can increase the toughness, compression. Fibers for concrete thus is used widely in the project of tunnels, roads, bridges, civil engineering, water conservancy, mining, metallurgy, ports, airports and other concrete construction.

Steel fiber is high-risk products in construction, its quality make direct impact on the building’s security. Therefore, clients are interested in those products that pass CE certificate. Factory inspection should be conducted, thus, the whole production techniques are controlled by the European standard.

Fibers for concrete are including: steel fiber and polymer fiber.
