Founded in 2015 and strategically located in Jiujiang, Jiangxi Province, China Beihai has emerged as a high-tech powerhouse. We specialize in the research, development, and mass-scale production of high-performance continuous basalt fiber (CBF). As a leading enterprise in China's basalt industry, our focus integrates raw material processing with advanced equipment manufacturing to ensure end-to-end quality control.
Our mission is to replace energy-intensive materials with eco-friendly basalt fiber solutions, reducing the carbon footprint across global supply chains.
Basalt fiber is manufactured by melting volcanic basalt rock at high temperatures (approx. 1450°C) and pulling it into continuous filaments. Our roadmap focuses on increasing the tensile modulus through advanced furnace homogenization and proprietary sizing agents.
The next generation of "Lightweight Basalt Fiber" will incorporate nano-coatings to enhance the bonding interface between the fiber and polymer resins, pushing the limits of impact resistance and durability in extreme environments.
Unlike carbon fiber, basalt is 100% recyclable. Our future development is geared towards a lower Life Cycle Assessment (LCA), making it the "Gold Standard" for sustainable construction by 2030.
From bridge pier protection to high-speed rail sleepers, our basalt rebar prevents internal corrosion—the primary cause of concrete structural failure in coastal regions.
Used in aircraft wings and engine heat shields, basalt's non-combustibility and electromagnetic transparency offer unique safety advantages over glass or carbon fibers.
Achieving significant weight reduction in brake pads, mufflers, and interior composites, enhancing fuel efficiency and meeting rigorous EV thermal safety standards.
Its inherent resistance to acids, alkalis, and salts makes basalt fiber the ideal reinforcement for underground storage tanks and corrosive chemical piping.
Leveraging China's manufacturing prowess, our Jiujiang facility utilizes AI-driven process monitoring to ensure batch-to-batch consistency.
Integrated pultrusion and weaving lines reduce intermediate handling, lowering costs and minimizing fiber damage. Our scale allows for rapid prototyping of custom basalt fiber products.
Proximity to high-quality basalt quarries ensures a stable supply chain, insulating global partners from raw material price volatility seen in synthetic fiber markets.
As a specialized factory, we offer bespoke filament diameters (7μm to 22μm) and specialized chemical sizings tailored to specific resin systems (Epoxy, Vinyl Ester, etc.).
China Beihai products are tested against international benchmarks including ASTM, ISO, and CE certifications. We provide comprehensive technical data sheets (TDS) and safety data sheets (SDS) for all exports.
Our localized support team assists global engineers in translating basalt fiber properties into structural design software (FEA), ensuring safe and compliant project integration.
