TUF-Strand SF is a high-performance macro synthetic fiber engineered to replace steel fibers, welded wire mesh, and light rebar in concrete applications.

Made from a proprietary blend of polyolefin materials, it provides superior toughness, ductility, and impact resistance to concrete.

Disperses uniformly throughout the mix, creating a three-dimensional reinforcement network that controls cracking and enhances structural integrity.

Designed for industrial floors, precast elements, pavements, tunnels, and shotcrete applications.

Offers an efficient, corrosion-free, and cost-effective alternative to traditional steel reinforcement.
