Selection logic

Geometry must match the performance requirement

Hooked ends develop mechanical anchorage during crack opening. Straight micro fibers rely on high fiber count, matrix bond and dispersion in dense cementitious systems.

Length, diameter and aspect-ratio concept
Hook or straight geometry
Wire tensile strength and ductility
Loose or glued bundle format
Residual-performance test requirements
Batching, pumping and finish constraints

Standards and testing

Specify the test outcome, not only the fiber name

Projects may reference material classification and concrete flexural-performance methods. The applicable edition and acceptance criteria belong in the project specification.

ASTM A820/A820MSteel fiber material classification and dimensional requirements where specified.

ASTM C1116/C1116MSpecification framework for fiber-reinforced concrete.

ASTM C1609/C1609MFlexural performance of fiber-reinforced concrete using beam testing.

EN 14889-1 / ISO 13270Use only where the supplied product and project documentation support the required framework.

Steel-fiber selection language

Read geometry and material properties as a system

LengthControls embedment across a crack and must suit aggregate size, element geometry, pumping and placement.

DiameterInfluences fiber count for a given mass and is used with length to describe aspect ratio.

Aspect ratio (L/d)Fiber length divided by characteristic diameter. It is a comparison variable, not a performance guarantee by itself.

Tensile strengthUseful only with suitable anchorage, bond and concrete response; required values must come from the selected product data.

Anchorage and formatHooks, deformation, loose supply or glued bundles influence pull-out and batching behavior.

Coating / steel gradeBright, galvanized or stainless options require source-specific exposure, grade and documentation review.
