Revolutionizing Concrete: Unveiling 3MAX Fiberglass Rebar

Property owners might not have heard of fiberglass rebar, but this innovative construction material has been around for 40+ years! Crafted as a revolutionary alternative to traditional steel supports, it is a high-strength composite reinforcing bar meticulously engineered for concrete flatwork. Its innovative composition is a beacon, surpassing traditional #3 and #4 grade 40 rebar.

Ingenious Composition of 3MAX Fiberglass Rebar

A strategic blend of materials lies at the core of this reinforcement, ensuring unparalleled durability.

The manufacturing process of 3MAX Fiberglass Rebar is a testament to precision and technological advancement. The combination of vinyl ester resin and ECR glass fibers undergoes a meticulous fabrication process, ensuring each bar meets the highest quality standards. The result is a composite rebar that exceeds strength expectations and showcases consistency and reliability.
