Global Export Network
Founded in 2015 and strategically situated in Jiujiang, Jiangxi Province, China Beihai is a premier high-tech enterprise focusing on the continuous research, engineering, scaling, and sales of high-performance continuous basalt fiber. Equipped with advanced melt-spinning technology, we specialize in high-capacity raw basalt melting and continuous multi-filament spinning to manufacture top-tier structural composite products.
We possess an integrated industrial footprint, which allows us to control the entire manufacturing process—from direct quarry sourcing of specific volcanic basalt rock to processing final structural elements, including continuous basalt rovings, chopped strands, rebar, woven fabrics, and customizable structural sleeves or tape.
We leverage advanced geology, high-temperature fluid dynamics, and automated machinery to provide unmatched value.
At China Beihai Group, we specialize in high-strength basalt roving, chopped strand mats, woven cloths, continuous yarns, structural rebar, and custom fireproof sleeves. We offer dynamic solutions that bridge architectural demand and raw material synthesis.
We do not just produce bulk fibers; we calibrate basalt compositions. From adjusting sizing chemistry to match specialized resins to offering precision tex values (from 600 to 4800 tex), our engineers match specific client design criteria for tensile, flexural, and shear requirements.
Partnering with China Beihai ensures high quality assurance. With optimized batch uniformity, state-of-the-art furnace thermal stability, and low coefficient of variation in fiber diameter, we provide high-performance fiber products with minimal mechanical degradation.
A comprehensive research-grade breakdown of Continuous Basalt Fiber (CBF) technology, mechanical structures, supply-chain dynamics, and global price architectures.
Continuous Basalt Fiber (CBF) is an inorganic fiber extruded from molten volcanic basalt rock at temperatures ranging from 1450°C to 1500°C. Composed of silicon dioxide (SiO₂), aluminum oxide (Al₂O₃), calcium oxide (CaO), magnesium oxide (MgO), and iron oxides (FeO and Fe₂O₃), basalt roving possesses inherent atomic advantages over conventional glass fiber (E-glass) and competitive metrics compared to high-performance S-glass and carbon fibers.
Unlike composite materials that blend synthetic materials, basalt roving is 100% natural, biologically inert, and boasts high thermal insulation, acid/alkali corrosion resistance, and high tensile mechanical strength. With a modulus of elasticity surpassing 85-90 GPa and a tensile strength range exceeding 2800-4000 MPa, continuous basalt fiber allows designers to engineer extremely thin, ultra-lightweight structural laminates with high load-bearing capacity and impact resistance.
"Continuous Basalt Fiber sits at the intersection of extreme thermal resistance and heavy-duty structural reinforcement. Its natural chemical composition forms a highly stable silicate network, impervious to strong acids, high-salinity marine air, and extreme alkaline concrete mixtures."
As a leading hub for global basalt continuous fiber manufacturing, China offers deep supply-chain stability. China Beihai’s facilities in Jiujiang, Jiangxi, leverage domestic technological infrastructure to scale up production capacity while maintaining rigorous quality control.
Our factory relies on advanced single-component raw material melting technology. By heating selected high-purity basalt stones in fully automated multi-bushing furnaces, we eliminate chemical impurities and regulate fiber diameter down to the micron level (typically 9μm to 22μm). This raw material stability, coupled with lower local energy costs and complete upstream-downstream integration, enables us to manufacture top-tier high-strength basalt roving at highly competitive wholesale prices compared to Western producers.
Global industrial buyers evaluating basalt roving must assess total cost of ownership (TCO) rather than just initial purchase price. The pricing structure of custom basalt roving depends on several parameters:
Deploying basalt continuous fiber composites globally requires strict alignment with localized construction codes and environmental regulations. China Beihai prioritizes systematic testing and certification to ensure our materials fit into complex regulatory environments:
Our product formulations undergo extensive ASTM testing to establish certified design values for tensile strength, shear resistance, thermal expansion, and durability in marine environments. For European applications, we conform to REACH and RoHS chemical safety frameworks, ensuring that no harmful organic binders or hazardous heavy metals leach out during the product’s multi-decade lifecycle.
Demonstrating how basalt fibers outperform legacy materials in complex engineering environments.
Reinforcing concrete structures, highways, and bridge decks. Basalt rebar completely prevents internal oxidation and concrete cracking.
Manufacturing lightweight structural components, internal cabin soundproofing, and thermal insulation shields for spacecraft engines.
Ideal for lightweight automotive panels, structural brake pads, exhaust silencers, and highly resilient structural composites.
Corrosion-resistant piping, underground storage tanks, and offshore drilling platforms subject to aggressive organic solvents.
Tested by globally recognized quality verification institutions to assure absolute mechanical performance.
Detailed technical answers for composite engineers, procurement managers, and industrial designers.
As intelligent drones inspect harsh, chemical-heavy industrial fields and deep sea platforms carry out continuous operations, structural reliability has become the key differentiator. Basalt continuous fiber composite solutions serve as the "hardcore support" behind smart next-generation equipment, keeping components light, strong, non-conductive, and completely rust-proof.
