Loose Hooked-End Steel Fibres

About

Loose Hooked-End Steel Fibres

Discrete, unbundled hooked fibres for maximum flexibility and anchorage in large-volume and general concrete reinforcement.

Loose hooked-end steel fibres are individual (unbundled) fibres with hooked ends on both ends. Because they are loose, they allow maximum flexibility in dosing, mixing, and adaptation to concrete design. Hooked ends ensure strong mechanical anchorage, controlling crack width even under heavy loads or cyclic stresses. These are a standard, proven solution in general structural, industrial, and infrastructure concrete reinforcement. Widely used in flooring, pavement and precast applications, they offer the same mechanical performance without the need for glue.

Key Features

Maximized Anchorage

Hooked ends give strong pull-out resistance, improving residual strength post-cracking.

Flexible Dosing

Being loose, they adapt well to different mix designs, batch sizes, delivery and dosing modes.

Proven Durability

Well tested in many standard concrete reinforcement applications.

Relative Cost Efficiency

Without bundling/glue, manufacturing and handling costs are lower, which can translate to savings for large-volume use.
