Leading the market with precision-engineered basalt composites.
Basalt fiber is no longer a niche material. As the world pivots toward the "Carbon Neutral" goals of 2050, basalt fiber (produced by melting volcanic rock at 1450°C) offers a 80% lower carbon footprint than carbon fiber. It is the definitive green alternative for sustainable industrial growth.
From the high-speed rail networks in Asia to the bridge seismic retrofitting in North America, China Beihai’s basalt solutions are replacing traditional steel and E-glass. Our bulk yarn production capabilities meet the intensive demands of global supply chains.
Unlike glass fiber, basalt is 100% natural and non-toxic. During processing and end-of-life disposal, it poses no environmental threat, aligning with EU and US strict ecological regulations for construction materials.
China Beihai's R&D department has established a rigorous technical roadmap focusing on Surface Silane Sizing and Multi-Filament Homogeneity. This ensures that our Basalt Fiber Yarn Bulk products achieve maximum resin compatibility (Epoxy, Polyester, Vinyl Ester).
Our 2024 technical update introduces high-speed air-jet texturizing for basalt yarns, allowing for bulk orders that maintain zero-defect counts over 100,000 meters. This is critical for automated pultrusion and filament winding processes.
Through plasma treatment, we increase the surface roughness of the fiber at the nano-scale, enhancing the interfacial shear strength (IFSS) between the fiber and the composite matrix by 35%.
Founded in 2015 and headquartered in Jiujiang, Jiangxi Province, China Beihai is a high-tech titan in the high-performance basalt continuous fiber industry. We specialize in the full lifecycle of basalt fiber—from raw material melting to final composite fabrication.
Solving specific engineering challenges with basalt technology.
In coastal regions, salt-spray corrosion destroys steel-reinforced concrete. Our basalt fiber rebar and wraps provide a lifetime of 100+ years with zero maintenance in high-salinity environments.
Utilized in drone fuselages and spacecraft thermal shields, our basalt yarn offers electromagnetic transparency, making it superior to carbon fiber for communication-heavy aerospace applications.
Replacing E-glass in brake pads and engine covers, basalt fiber reduces vehicle weight by 20% while providing superior heat dissipation and vibration damping.
Our basalt fireproof fabrics are integrated into high-rise curtain walls. Unlike polymers, basalt does not melt or emit toxic gases when exposed to direct flame at 1000°C.
China Beihai is investing in AI-driven melt-furnace control systems to reduce energy consumption by another 15%. We are also developing Basalt-Carbon Hybrid Yarns to achieve the stiffness of carbon with the toughness of basalt at a 40% lower price point.
We provide localized technical data sheets (TDS) and safety data sheets (SDS) compliant with GHS standards. Our engineering team offers on-site consultation for large-scale infrastructure projects to ensure correct fiber dosage and application techniques.
