Why Is 18mm Monofilament Synthetic Fiber Our Strongest Structural Fiber Option?
At 18mm, we’re at the top of our synthetic fiber range — the length engineered for the heaviest structural demands our fiber lineup addresses. This is the product we point to when a project genuinely needs macro-level reinforcement: think heavy industrial flooring, pavements carrying sustained vehicle loads, or precast structural elements where post-crack load capacity isn’t a nice-to-have, it’s a design requirement. As a Macro Synthetic Fiber Manufacturer, this fiber represents the furthest point on our range from basic shrinkage control, built specifically to compete with — and in many applications replace — traditional steel fiber and wire mesh.
The extra length compared to our 6mm and 12mm synthetic fiber variants gives this product significantly greater crack-bridging reach and load transfer capacity, which is exactly what’s needed when a slab or pavement section is expected to keep performing structurally long after the first crack appears.
Product Overview
Manufactured using our engineered synthetic polymer formulation, this 18mm fiber is produced to deliver the highest tensile and post-crack performance in our range. As a serious Concrete Reinforcement Fiber Manufacturer alternative to steel reinforcement, we hold this product to strict quality benchmarks, since it’s typically specified in applications where structural performance is verified through design calculations, not just general assumption.

Key Features
This fiber’s length gives it substantial post-crack load-carrying capacity, meaning the concrete section retains structural performance well beyond initial crack formation — a critical property in heavy industrial flooring and pavement design. Being fully non-metallic, it eliminates the corrosion risk that eventually compromises steel fiber and wire mesh in moisture-exposed or coastal environments, without sacrificing the structural contribution steel is traditionally relied on for. It’s also considerably lighter than an equivalent steel reinforcement system, simplifying handling and reducing dead load on the structure.
Recommended Dosage
For heavy industrial flooring and structural pavement applications, dosage typically ranges from 3–6 kg per cubic meter, depending on the specific structural design and load requirements. Given the structural implications involved, dosage for this product should always be confirmed against a validated mix design and, ideally, reviewed with a structural engineer alongside our technical team — this isn’t a fiber where general estimates are appropriate.
Mixing Compatibility
Compatible with ready-mix concrete and site-batched concrete used in industrial flooring and heavy pavement applications. Adequate mixing time should be allowed at the higher dosage rates typical of structural applications to ensure full, even dispersion throughout the batch. Compatible with standard admixtures including plasticizers, accelerators, and curing compounds.
FAQ
Can 18mm synthetic fiber fully replace steel fiber in industrial flooring?
In many industrial flooring designs, yes — though the final specification should always be confirmed through structural engineering review based on the specific load and design requirements of the project.
What makes 18mm the right choice over shorter synthetic fiber variants?
Its longer length provides significantly greater crack-bridging reach and post-crack load capacity, making it the appropriate choice for heavier structural demands than our 6mm or 12mm synthetic fiber options address.
Is this fiber suitable for pavement applications carrying heavy vehicle traffic?
Yes, it’s specifically engineered for these demanding applications, offering fatigue resistance and sustained load-carrying performance under repeated heavy traffic.
