ROCK FIBER INC.
Rebuilding the Composites Marketplace


Rock. Reengineered.
RockFiber Inc. uses a proprietary induction process to fiberize igneous
rock, engineering its natural strength into a high-performance material
for advanced structural composites. With near-zero emissions.
Molten rock erupts from deep within the Earth at 1,100°C, hardening
as it cools into a material that's dense, mineral-rich, and structurally
strong by nature. The perfect raw material for a high-performance fiber.
The game changing potential of rock-based fiber has been researched and recognized for decades. Producing it at industrial quality and scale has been the barrier- until now.

Rock Fiber Inc. is developing a new, superior and cost-effective fiber for reinforcement. Our fiber allows for lighter, stronger, more durable composites. From seawalls, to windows frames to bullet trains, we're engineering a fiber reinforcement product to move the world forward. Redefining what is possible in manufacturing.
In construction, this strength and durability translates to concrete reinforcement solutions that reduce or eliminate steel, prevent cracking and corrosion, and extends the life of the structures we build. Shortening timelines, reducing maintenance and downtime along the way.
Reinforcement. Redefined.

One of Earth's most abundant materials. Reengineered for what's next.
