- Increase fatigue resistance and toughness
- Provide long term durability of concrete
- Reducing embodied carbon through the replacement of convention steel reinforcement with synthetic structural fibers

Macro Synthetic Fibers had shown excellent performance in multiple applications

Macro Fiber for Shotcrete
- Improve the tensile strength, shear strength and fatigue resistance of concrete
- improve the toughness of concrete, better resist deformation and extend service life
- Significantly improve the construction performance of shotcrete
- Reduce the rebound rate of shotcrete by 80%-90%.
Macro Fiber for Precast Concrete
- Reduce cracks in precast concrete and maintain structural integrity.
- improve the toughness of concrete, better resist deformation and extend service life
- Significantly improve the tensile strength of precast concrete.


Macro Fiber for Slabs on ground
- Improve the tensile strength, shear strength and fatigue resistance of concrete
- improve the toughness of concrete, better resist deformation and extend service life
Macro Fiber for Pavement
- Improve the tensile strength, shear strength and fatigue resistance of pavement
- Resistant to high temperatures, less pavement damage.
- Note: After adding fibers, the viscosity of concrete mixture increases, and the roller should be crushed 2-3 times more than ordinary mixture.Or extend the vibration time for about 30 seconds as appropriate, and wipe the surface of the concrete after it is slightly blunted, so as not to bring out the fibers.


Macro Fiber for Composite Metal Deck
- Further improve the waterproof performance of composite metal decks.
- Improved corrosion resistance and longer service life.
Packing:More environmentally friendly!
20kg or 40kg / box , with water soluble bags.
Custom bag sizes are available.
