Steel fibre with hooked ends

KrampeHarex steel fibres with hooked ends are manufactured in their own manufacturing plant in Hamm, Germany. They are produced in different diameters and lengths, depending on the application field and customer requirements. The surface of the fibre is usually slightly grained. The raw materials are steel ribbed bars and the products contain no SVHC substances. Steel fibres with hooked ends are used as concrete reinforcement in combination with or as a substitution to rebars or meshes. The steel fibres bridge cracks of small width, distribute the stresses and increase the strength of the concrete in the cracked state. By adding a determined number of fibres in the concrete, tensile and shear strength, impact strength and fatigue resistance are increased.
