Repeatable production
Batch consistency, orientation, mold filling, finish and quality testing matter alongside fiber properties.
Regular Supply
4D-Type Glued Hooked-End Steel Fiber
A regular-supply, specification-driven hooked-end pathway for projects requiring higher-strength fiber options, controlled batching and documented residual performance.
Regular Supply
Verified UCGP commercial evidence
One confirmed quoted configuration
UCGP records include a glued steel fiber identified as 4D-type / 80/60 BG or equivalent. These values describe that quoted configuration, not every product available.

FormatGlued bundle
Other configurationsConfirmed against supplier documentation and quotation.
Brand terminologyManufacturer identity and permitted product naming confirmed per source.
Why glued bundles are used
Batching support without changing the fiber mechanism
Water-soluble glue can hold fibers in bundles during dosing. In the mixer, the bundle separates so individual hooked fibers can distribute through the concrete. Actual addition sequence and mixing time follow the supplied product instructions and plant trial.
- Controlled dosing into the mixer
- Reduced tendency for fiber clumps when handled correctly
- Homogeneous distribution remains a production-control task
- Keep supplied packaging dry and follow source instructions
Specification-led applications
Residual performance drives selection
Tunnel segments, precast components, infrastructure and demanding slabs may specify post-crack values rather than only a fiber dosage.
Documented acceptance
Product data, material standard, concrete test method and approval responsibilities must align.
System design
Loads, subgrade, joints, slab geometry, concrete and residual performance are considered together.

Plant trial observations
Verify separation and distribution, not only addition
Bundle separationConfirm glued bundles disperse into individual fibers during the selected mixing sequence.
WorkabilityRecord consistency before and after fiber addition; use the approved mix/admixture approach rather than uncontrolled water.
DistributionInspect for visible fiber balls, uneven concentration or incomplete bundle separation.
Placement routeTrial pumping, discharge, placing and finishing with the actual equipment and element geometry.
Performance evidenceUse the project-specified residual or toughness test and acceptance criteria.
Supply confirmationExact grade, packaging, MOQ and lead time are confirmed per quotation.
