Quality Twisted Macro-Synthetic Fiber

The Tenabrix manufacturer’s unique production process results in superior twisted macro-synthetic fiber quality.
Tenabrix twisted macro-synthetic fiber plays an irreplaceable role in concrete applications.In particular, it shows excellent performance in durability, crack resistance and toughness.

What is Twisted Macro-Synthetic Fiber?

        TenaBrix® Twisted Macro Synthetic Fiber is a high-performance fiber composed of a blend of polypropylene and polyethylene resins, specifically engineered to enhance the durability and performance of conventional concrete, pre-cast concrete, and shotcrete. 

        Its unique twisted bundle design creates a strong mechanical bond with the concrete matrix, providing tensile and bending properties comparable to traditional steel reinforcement. This innovative fiber significantly improves crack resistance and toughness, making it an ideal replacement for steel fibers in fiber-reinforced concrete, while optimizing the overall structural integrity of the material.

Excellent performance

Superior Crack Control

Distributes stress more evenly throughout the concrete, effectively controlling cracks caused by shrinkage, temperature fluctuations or load stresses and preventing large cracks from forming.

Enhanced Toughness

These fibers bridge cracks, providing additional support, allowing the concrete to absorb more energy before failure, which significantly improves the toughness of the concrete.

Excellent Corrosion Resistance

Twisted Macro-Synthetic Fiber is unlike with traditional steel fiber, synthetic fibers do not corrode, making them especially suitable for use in corrosive environments.

Reduced Construction Costs

Compared to traditional rebar placement, twisted macro-synthetic fibers are easier to mix into concrete, significantly reducing construction time and labor costs.

Why Choose Tenabrix Twisted Macro-Synthetic Fiber?

  • Durable and Long-Lasting Unlike steel fibers that can rust, synthetic fibers ensure long-lasting performance with minimal maintenance.
  • Versatile Applications Performs exceptionally well in extreme temperatures and moist environments, making it a versatile choice for various concrete applications.
