A Loose Hooked-End Steel Fibre is a short, high-strength metallic filament with small hook-shaped ends that mechanically anchor into concrete. Unlike bundled or glued fibres, "loose" fibres are free-flowing and non-clumping, allowing rapid dispersion during batching.
These fibres distribute randomly throughout the concrete matrix, bridging microcracks as they form. As stresses increase, the hooked ends effectively "lock" within the cementitious structure, providing post-crack load-bearing capacity and preventing sudden structural failure.
This technology transforms concrete from a brittle material into a ductile, high-performance composite — capable of withstanding impacts, vibrations, and tensile stresses that traditional mixes could not endure.
