Roman Stone partners with Rock Fiber, introduces basalt fibers to U.S. precast concrete market
MiniBars reinforcement is four times stronger than traditional rebar and weighs 30% less, in addition to delivering strength, ductility and greener benefits.

Precast concrete company (Bay Shore, N.Y., U.S.) is now partnering with to introduce MiniBars, a reinforcement product made from basalt fiber-reinforced macro-fibers, to the U.S. precast concrete industry.
“Bringing MiniBars to our precast portfolio will give the industry a smarter, faster and more durable way to build,” says Daniel Murray, president and CEO of Roman Stone. “The addition of this novel reinforcement gives us the ability to streamline our manufacturing processes and enables us to offer a more sustainable and durable product for our customers far beyond a traditional precast product.”
Through its own extensive engineering and testing, Roman Stone has proved that the performance of the MiniBars enables the company to develop, engineer and launch new products in less time versus traditional product development. Additionally, the product is substantially stronger, more durable and — most importantly — greener.
MiniBars are engineered to replace or reduce traditional steel reinforcement. Designed to mix evenly throughout concrete, they provide uniform reinforcement and deliver optimal post-crack strength, impact resistance and fatigue durability, without the drawbacks of other macro-fibers.
Composite MiniBars made with basalt fibers deliver four times the strength of conventional rebar at just 30% the weight of rebar, and flood the concrete matrix, delivering strength and ductility throughout while being immune to corrosion, ensuring longer service life in harsh environments such as marine, wastewater and de-icing salt exposure. Using fibers produced directly from volcanic rock, MiniBars also have a substantially lower carbon footprint than steel without corrosion and support longer lifecycle infrastructure.
MiniBars also eliminate the need for rebar cages, saving labor and fabrication time while enabling thinner, lighter precast units.
