Why use macro synthetic fibers in industrial floors?

Macro synthetic fibers improve load distribution, toughness, durability, and eliminate corrosion—making them ideal for industrial floor slabs.

What dosage of macro fibers is recommended for industrial slabs?

Typical dosages range from 4–6 kg/m³ for standard warehouses, 6–8 kg/m³ for heavy forklift traffic, and 8–10 kg/m³ for logistics or container yards.

Do macro synthetic fibers replace steel mesh?

Yes, macro synthetic fibers can replace steel mesh by providing full-depth reinforcement and eliminating corrosion and placement errors.

Suitable for architectural engineers, structural engineers, flooring contractors, precast component manufacturers, and technicians.

Industrial floors face extreme loading, frequent traffic, impact forces, and temperature gradients. Traditional reinforcement systems—such as welded wire mesh (WWM) and steel fibers—are increasingly replaced by macro synthetic fibers like HTM® Mono, HTM® Twist, and HTM® Emb.

This article explains why macro synthetic fibers deliver superior performance and reliability for industrial slabs-on-ground.

Challenges in Industrial Floors

Industrial slabs must withstand:
Repetitive forklift & truck loading
Impact from dropped loads
Abrasion and surface wear
Shrinkage and curling
Temperature variations
Lack of uniform support from subgrade

Traditional reinforcement limitations

WWM is often misplaced or resting on subgrade
Steel fibers increase mixing equipment wear
Steel is prone to corrosion
Labor-intensive installation

Why Macro Synthetic Fibers Provide Superior Performance

Macro synthetic fibers deliver multiple benefits across the entire slab thickness.

1. Better Load Distribution

Fibers form a 3D reinforcement matrix, unlike steel mesh which reinforces only one plane.

This improves:

Crack width control
Load transfer efficiency
Joint stability
Slab uniformity

2. Improved Impact and Fatigue Resistance

HTM® Mono and HTM® Twist absorb high levels of energy during pull-out, creating a ductile slab that withstands dynamic and repetitive loading.

3. Safer and Faster Installation

Using macro fibers eliminates:

Mesh placement
On-site cutting
Rebar tying
Crane lifting
This saves up to 30–40% labor time.

4. Zero Corrosion Risk

Polymer macro fibers do not rust, eliminating long-term durability risks—especially in:

Cold storage
Chemical plants
Coastal environments

5. Better Joint Performance

Macro fibers reduce joint spalling by improving load transfer between slabs. Many engineers use macro fiber dosages to increase joint spacing, reducing maintenance needs.

HTM® Fiber Options for Industrial Flooring

Different HTM® macro fibers suit different engineering needs:

Fiber Type	Characteristics	Best Use
HTM® Mono	Easy mixing, balanced toughness	Standard industrial slabs
HTM® Twist	High mechanical anchorage	Logistics centers
HTM® Emb	Maximum pull-out resistance	Heavy-duty floors

Dosage Guidelines

Typical industrial flooring dosages:

Standard warehouse：4–6 kg/m³

Heavy forklift / rack loading：6–8 kg/m³

Container yards or heavy logistics：8–10 kg/m³

Conclusion

Macro synthetic fibers provide a safer, cost-effective, and high-performance reinforcement system for industrial floors. The HTM® macro fiber family enhances ductility, toughness, and durability, making it an ideal choice for modern slab-on-ground designs.
