Basalt Fiber Reinforced Polymer Composites (BFRP)

Basalt Composite Rebar is manufactured with innovative Basalt Fiber Reinforced Polymer composite technology. Basalt (volcanic) rock adds unmatched strength, with superior mechanical properties and enhanced performance compared to competitive reinforcements. Basalt Rebar is a sustainable, rust-proof alternative to traditional steel reinforcement. It is only 25% of the weight of steel and has a Specific Tensile Strength that is 2.5 times greater! Basalt Rebar is the ideal choice for concrete construction applications.

Basalt Rebar Product Comparison

  • Basalt is impervious to attacks from alkali, chemicals or water, which causes Steel to corrode or rust.
  • Basalt has stable pricing, no buy-ups required to secure best pricing compared to steel which fluctuates.
  • Basalt has 2 times the working temperature (400°C vs. 200°C) of Glass FRPs.
  • Basalt has 20 - 40% better mechanical properties and puncture resistance than Fiberglass.
  • Basalt is very Eco-Friendly vs. other products.

Green Building Materials

Basalt Reinforced Rebar has less than 1/10th the carbon footprint of steel and basalt has the lowest environmental impact in a Life-Cycle Assessment compared with other FRP (Fiber Reinforced Polymer) rebars. Basalt fiber is all natural and produced from stone; without additives typically found in other materials such as glass fiber.
