Rockfiber

What Rockfiber does

Rock Fiber Inc. (DBA Rockfiber) is a Houston, Texas-based advanced materials company founded in 2022 that manufactures basalt fiber from igneous rock using a proprietary induction melting process. The company's core technology transforms igneous rocks (basalt, andesite) into high-performance, environmentally friendly fibers using an induction process that claims near-zero emissions, better temperature control, and the ability to accept a wider range of rock inputs than conventional methods. Its product portfolio centers on Rockfiber™, a basalt fiber material offered in roving and chopped forms for fiber-reinforced polymer (FRP) composites used across industries from athletic equipment to aerospace, and MiniBars™, a high-performance basalt macrofiber engineered to replace or reduce steel reinforcement in concrete for bridges, sea walls, precast products, and large industrial slabs.

The business model is hardware sales of basalt fiber materials to FRP composite manufacturers and infrastructure/construction end-users. MiniBars are distributed exclusively in the Americas through ReforceTech Americas (RFTA), a March 2025 joint venture with ReforceTech, and through a September 2025 channel partnership with Roman Stone for the U.S. precast market. The company also pursues direct enterprise sales (contact: Rob Klawonn, [email protected]). Capital formation to date consists of an SEC Form D exempt securities offering filed in August 2024, targeting $5 million with $1.2 million sold at a $100,000 minimum investment. Rockfiber positions its materials as a cost-competitive, drop-in substitute for glass fiber with claimed end-use benefits of 100% steel reinforcement reduction, 50% concrete reduction, 50% labor reduction, and 50% carbon footprint reduction in concrete applications.

The company operates with 1–10 employees and a leadership team with deep domain credentials: CEO Col. Bryan Green (former U.S. Army Corps of Engineers Commander), President/COO Rob Klawonn (ex-Teijin N.A. President, ex-4M Carbon Fiber CEO, 30+ years composites), Founder/CTO Alex Biland (25+ years igneous rock fiber fabrication, multiple patents), and Board Chairman Gerry McDougall (former PwC senior partner). The company does not disclose revenue, production volume, or named end-customers, and is currently in a pre-commercial to early-commercial stage.
