Steel fiber EN 14889-1:2006
Steel anchoring fibre is a product made from high-strength steel wire with a tensile strength of at least 1100 MPa, specially designed to be used to reinforce concrete structures, in an amount of 20 to 25 kg per cubic metre of concrete mortar.

Steel anchor fibres are an alternative to traditional concrete reinforcement methods, such as reinforcement cages and masonry mesh. The fibres are distributed evenly throughout the concrete mass, providing more uniform support and increased tensile and flexural strength. This reduces material and construction costs, especially where large masses of concrete are needed - floors, roads, tunnels, and more. Construction time is reduced by 30-40%.
We offer steel fibres in different sizes and strengths for different projects.
