We deliver eco-friendly, highly sustainable industrial textile and structural reinforcement elements. We partner closely with infrastructure constructors, petrochemical giants, and aerospace manufacturers.
Our uncompromised commitment to strict international quality standards, active technology integration, continuous optimization of thermal drawing, and highly tailored support for global custom requests.
Basalt fiber represents the most significant breakthrough in industrial material science of this century. Engineered directly from natural volcanic igneous rocks through advanced single-component high-temperature melt drawing, it delivers superior structural and thermo-chemical characteristics. Our specialized Twisted Basalt Fiber Yarn leverages multiple micro-filament configurations (ranging from 9μm to 15μm) combined with precise mechanical twisting cycles to dramatically enhance structural coherence, tensile strength, and composite wet-out qualities.
Unlike organic or plastic-based glass fibers, twisted basalt yarn exhibits a vast operational thermal threshold, ranging from -260°C to up to +700°C (with a melting point exceeding 1450°C). It does not experience catastrophic softening or drop in yield strength, making it ideal for exhaust wrap systems, insulation tapes, and extreme cryogenic or high-furnace environments.
The chemical composition of basalt (rich in SiO₂, Al₂O₃, Fe₂O₃, and CaO) offers superb natural defense mechanisms against highly alkaline environments, acid attacks, moisture absorption, and salt sprays. Twisted basalt yarn maintains close to 85% of its initial tensile strength even when submerged in alkaline concrete environments for extended periods, far outstripping E-glass fibers.
With an elastic modulus exceeding 85 GPa and tensile strength breaking the 3000 MPa mark, twisted basalt yarn delivers critical structural stiffness and durability while maintaining high lightweight indices. The mechanical twisting of the filaments adds physical interlocking, preventing structural slippage and dramatically reducing surface micro-abrasions during high-speed weaving processing.
For procurement managers and composite engineers looking to optimize their structures, comparative analysis proves why basalt is rapidly replacing classical reinforcing materials across high-spec industries.

China Beihai Group stands at the forefront of automated basalt production, deploying proprietary furnace innovations and drawing systems that deliver massive technological advantages to global clients.
Operating from Jiujiang, Jiangxi, we leverage proximity to high-purity natural basalt deposits. The mineral composition provides a perfectly balanced silica-aluminosilicate raw state, which reduces impurities inside the finished yarn.
Our facility uses advanced multizone, fully closed electric melting furnaces. These furnaces sustain a highly uniform, rock-liquid pool state at 1450°C. Maintaining this precise temperature eliminates micro-crystal inclusions and guarantees continuous fiber thread integrity.
Equipped with high-performance ring twisting and assembling machines, we offer customized twists (S-twist or Z-twist), adjusting thread counts from 68tex to 136tex and beyond. Custom sizing coatings ensure optimal compatibility with Epoxy, Phenolic, and Polyester resins.
Jiujiang's direct river-to-sea port transport channels enable efficient, cost-effective container shipping to any worldwide hub. Backed by strict QA, custom sizing profiles, and heavy-duty, moisture-proof export packaging, our supply lines remain resilient all year round.
From standard building infrastructure reinforcements to deep space technology protections, continuous basalt fiber products show outstanding performance in demanding application scenarios.
China Beihai runs on strict adherence to international quality baselines. Our manufacturing and sorting processes meet strict testing parameters to ensure full design safety margins in the field.
As global manufacturing transitions towards mandatory carbon limits and strict environmental oversight, basalt continuous fiber stands as a key 100% eco-friendly mineral material. With zero chemical additives during raw material drawing, the carbon footprint of basalt fiber production is over 60% lower compared to glass or carbon fiber manufacturing cycles, supporting green construction initiatives.
Traditional concrete structures reinforced with steel require costly rehabilitation cycles due to rust and chemical swelling. Advanced engineering groups are increasingly utilizing basalt FRP rebar and durability geogrid meshes. They bypass corrosion entirely, extending concrete service life from 50 years to well over 100 years, even in harsh coastal and high-salt road environments.
As unmanned aircraft and automated systems navigate industrial zones, lightweight material shielding becomes crucial. Because twisted basalt fiber operates as a highly efficient electromagnetic insulator, it provides transparent shielding for radio frequency and MRI scanners. This helps smart systems perform high-precision work with zero signal interference.
