Steel fiber for concrete

Steel fibers replace clasic reinforcement from bar and mesh in certain concrete structures. They are used to increase the concrete flexural strength and improve construction speed. We produce the fiber from our wire according to standard EN 14899-1. It is then packed into 20 kg bags to ensure easy handling at the construction site.
