Polypropylene Mesh Fiber, also known as PP Mesh Fiber, is an innovative synthetic fiber used in various construction applications to improve the strength and durability of concrete. It is made from 100% virgin polypropylene, adopting unique manufacturing process to make high strength bundle monofilament fiber. When the fiber is put into the concrete, concrete (or mortar) can effectively control concrete (or mortar) micro-cracks which is caused by plastic shrinkage, temperature changes and other factors, to prevent and inhibit the formation and development of cracks, greatly improved crack resistance of concrete, impact resistance and seismic capacity.
PP mesh fiber is widely used as a cost-effective alternative to traditional steel reinforcement methods due to its excellent features and advantages.

Application:
- PP mesh fiber is suitable for a wide range of construction applications, such as:
- Concrete floors and pavements
- Bridges, tunnels, and highways
- Precast and tilt-up concrete panels
- Shotcrete and gunite applications
- Industrial and agricultural floors
- Basement and retaining walls
- Parking garages
Storage:
PP mesh fiber should be stored in a dry and cool place, away from direct sunlight. Avoid exposing the fiber to heat, moisture, or humidity, as this may affect its quality and performance. It is recommended to use the fiber within six months of receiving it.
FAQ
Q. Can PP mesh fiber replace steel reinforcement in construction projects?
A. Yes, PP mesh fiber can be used as an alternative to steel reinforcement. It offers several advantages over steel, including corrosion resistance, lightweight, and easy handling.
Q. What is the dosage of PP mesh fiber for concrete?
A. The recommended dosage of PP mesh fiber is typically between 0.6 to 1.5 kg per cubic meter of concrete, depending on the construction application.
Q. Is PP mesh fiber easy to mix with concrete?
A Yes, PP mesh fiber can be mixed with concrete using a standard mix design. It is recommended to use a mechanical mixing system to ensure an even distribution of fibers.
