About Rock Fiber (USA)

Rock Fiber, Inc. (USA) is advancing the future of sustainable advanced materials manufactured in the USA. Using proprietary electric melting technology, we transform igneous rock into near zero-emission, high-performance fibers for use in composites that outperform commodity E-Glass and other conventional glass fibers. Through our joint venture ReforceTech Americas, we are rolling out MiniBars™—a next-generation basalt composite structural macro-fiber already in successful use across Europe—into the Americas. MiniBars™ are designed to replace structural reinforcements such as rebar and steel mesh in concrete, delivering superior tensile strength, enhanced ductility, and corrosion resistance. The result: reduced cost, shorter project timelines, and dramatically lower carbon footprints and increased lifespan across the built environment. By pairing cutting-edge materials science with scalable U.S. production, Rock Fiber, Inc. is enabling a new generation of lighter, stronger, and more sustainable composite solutions for industries worldwide—solutions that are not only high-performing but also cost-effective.
