Glued steel fibres are individual steel fibres temporarily held together in small bundles with a water-soluble adhesive. The bundles help fibres feed into a concrete mixer and separate during mixing, supporting more even distribution when the mix design and mixing procedure are suitable. Buyers should select them by matching fibre geometry, steel properties, dosage, concrete mix, and placement method to the project’s performance requirements—not by choosing a fibre from length alone.

This guide is for concrete producers, contractors, engineers, and procurement teams evaluating glued steel fibres for a specific application. It explains where they may be used, what information to compare, and what to prepare before requesting a quotation. Final selection and dosage should be confirmed through project specifications, engineering review, and appropriate mix trials.
Glued steel fibres are discrete steel elements arranged in collated bundles using adhesive that is designed to release in the concrete mixing process. After separation, the fibres are distributed through the concrete rather than remaining as intact bundles. Their purpose is to help control cracking and provide post-crack reinforcement, subject to fibre type, dosage, concrete properties, and design requirements.
They are not a direct replacement for every form of conventional reinforcement. Whether fibres can supplement or replace another reinforcement detail depends on the structural design, applicable project requirements, and approval process. Buyers should therefore treat fibre selection as part of a coordinated design and production decision.
Glued steel fibres may be considered for industrial floors, warehouse slabs, precast concrete, shotcrete, and other projects where distributed reinforcement or post-crack behaviour is part of the design brief. Their suitability depends on factors such as loading, slab geometry, exposure conditions, placement method, and finishing requirements. A product that suits one application should not be assumed to suit another without review.
Collated fibres can be useful where feeding individual loose fibres consistently is a concern. The bundle format can support dosing and handling, while the mixing process must still be designed to disperse the fibres. Confirm the intended mixing sequence and equipment with the concrete producer and fibre supplier before production.
Steel fibres are available in different lengths, diameters, shapes, and end configurations. Straight fibres, hooked-end fibres, and other shaped options can differ in anchorage behaviour and how they interact with the concrete matrix. The appropriate geometry depends on the project’s specified performance and the design method being used.
As an initial comparison only, commercial products may include fibre lengths of approximately 30–60 mm and diameters of approximately 0.5–1.0 mm. These figures describe broad examples, not a universal specification or recommendation. Ask the supplier for the exact dimensions, tolerances, shape, steel grade or declared material properties, and relevant product documentation for the option being considered.
Start with the performance requirement, not a preferred fibre size. Clarify whether the project is focused on crack control, residual flexural performance, toughness, or another specified property, and identify how that requirement will be assessed. If the design documents specify a test method or acceptance criterion, provide it to the supplier and concrete producer.

Review the slab or element dimensions, reinforcement arrangement, concrete strength class, aggregate grading, placement method, and finishing process. These details affect both fibre performance and practical workability. Fibre geometry and dosage should be reviewed as a system with the mix design, rather than selected in isolation.
Dosage is project-specific and must be determined by design requirements and verification. For early budgeting or trial planning, a project team may compare a preliminary range such as 20–40 kg/m3, but this is only an illustrative range and is not a design recommendation. Do not adopt a dosage without engineering review and confirmation through suitable mix evaluation.
Ask how the collated product should be introduced into the mixer, what mixing sequence is recommended, and how dispersion will be checked. The adhesive is intended to release during mixing, but the result depends on the product, equipment, batch size, and mixing conditions. Discuss workability, pumping or conveying needs, finishing, and any risk of fibre balling with the concrete producer before a full pour.
Request a technical data sheet and verify that the offered product matches the project specification. Depending on the project and destination market, you may also need material declarations, inspection documents, packaging details, or other supporting information. Confirm which documents are available for the specific product rather than assuming that every item applies to every order.
| Selection area | Questions to confirm |
|---|---|
| Performance | What design outcome and acceptance criteria are required? |
| Fibre geometry | What length, diameter, shape, and dimensional tolerances are specified? |
| Mix compatibility | Will the proposed fibre and dosage work with the aggregate, mixer, and placement method? |
| Documentation | Which product data and quality documents must be supplied for review? |
| Commercial terms | What are the order quantity, packaging, production schedule, and delivery requirements? |
Pricing for glued steel fibres depends on the selected geometry and material, order quantity, packaging, customization, and destination. Minimum order quantities and lead times can also vary with product configuration, current production planning, and shipping arrangements. Because these terms cannot be reliably inferred from a general guide, buyers should request a project-specific quotation.
For a useful quotation, provide the requested fibre dimensions or performance requirements, target dosage if already established, estimated total quantity, packaging preference, delivery location, and required delivery date. If the specification is still under development, state that clearly and share the project stage. This helps the supplier distinguish a budgetary inquiry from a confirmed purchase requirement.
BEKA supplies glued steel fibres and can help B2B buyers review product options against their stated application and procurement requirements. To begin a technical discussion, share your project type, applicable specification, preferred or required fibre geometry, concrete mix information, estimated order quantity, and destination. If any details remain undecided, identify the open items so they can be clarified during evaluation.
Before placing an order, align the proposed fibre with the project designer, concrete producer, and contractor responsible for mixing and placement. Confirm the applicable performance criteria, product documentation, trial requirements, and delivery schedule in writing. This creates a more reliable basis for comparing suppliers and moving from product inquiry to project approval.
Glued steel fibres can be considered for concrete applications that require distributed fibre reinforcement, provided the product is matched to the design objective, mix, and construction process. The practical next step is to gather the project specification, application details, mix information, estimated quantity, and delivery requirements, then use those inputs to evaluate product options and quotation terms. Contact BEKA with this information to discuss suitable glued steel fibre configurations and the documentation needed for your review.
