Founded in 2015 and headquartered in the pivotal industrial cluster of Jiujiang, Jiangxi Province, China Beihai has grown into a premiere high-tech enterprise focusing on the continuous research, engineering, development, and state-of-the-art production of continuous basalt fiber. Recognized domestically as a key drafting player for structural basalt fiber benchmarks, our corporate footprint bridges the gap between raw basalt melt science and scalable macro-engineering solutions.
Leveraging deep thermodynamic expertise, our factory designs and implements advanced crucible and gas pool furnaces capable of high-temp draw speeds that stabilize mechanical filament properties in high-volume outputs. We support multinational supply chains with consistent premium-grade materials optimized for challenging environments.
Why modern structural engineers are systematically phasing out E-Glass and conventional coatings in favor of raw volcanic basalt continuous reinforcement.
Operates seamlessly across extreme thermal fluctuations from -260°C to well over 820°C, providing unmatched structural integrity where carbon fiber and E-glass degrade rapidly.
Naturally inert and highly resistant to aggressive chemical exposures, such as salt sprays, alkaline concrete, and subterranean moisture systems.
Exhibits dynamic tensile strength parameters exceeding 3000 MPa and an elastic modulus reaching 89 GPa, delivering robust shear resistance and high modulus structural support.
Understanding structural performance requires analyzing primary material properties side-by-side. The table below represents certified benchmark values illustrating why basalt stands out as a high-performance alternative to conventional composite agents.

Woven basalt roving consists of multiple strands of continuous basalt fiber that are meticulously woven into bidirectional patterns, offering high-strength reinforcement. These patterns are designed to optimize multi-axial mechanical loads. Because basalt is manufactured from single-ingredient volcanic basalt rock without secondary chemical compounds, the material exhibits high structural stability under thermal stress. The unique composition minimizes structural shear deformation under continuous load cycles, making it highly effective for heavy industrial laminates, automotive structural panels, and seismic retrofitting layers.
How China Beihai Group integrates geopolitical resources, geological abundance, and technological innovation to command cost and quality leadership.
China is home to rich, chemically stable basalt reserves. The raw ore processed in Jiangxi possesses optimal concentrations of FeO and Fe2O3, which are critical for stable draw performance and consistent chemical composition. This geological advantage ensures that each production batch maintains reliable mechanical properties.
China Beihai Group operates multi-end draw lines utilizing modern automated feeding and temperature-regulation control systems. By scaling our operations, we minimize processing variances, maintain highly consistent yarn packages, and significantly reduce energy consumption per metric ton.
From raw basalt crushing and filament drawing to custom twisting, weaving, and rebar profiling, our production is completely integrated within one region. This eliminates inter-provincial shipping overheads and enables us to deliver highly competitive quotes and reliable delivery timelines.

Procuring woven basalt roving requires understanding structural variables that influence custom pricelists. Unlike fiberglass, basalt melting processes demand sustained temperatures above 1450°C. Fluctuations in fuel, natural gas, and raw electricity directly impact unit costs. Additionally, the following processing parameters shape manufacturer quotes:

Get answers to critical procurement questions about technical compatibility, international trade terms, and pricing metrics.
Pricing is influenced by raw material selection, target Tex density (typically 300 to 4800 Tex), weave architecture (plain, twill, or unidirectional), specific sizing requirements (epoxy, vinyl ester, or polyester compatible silane), and total order volume. Sizing compatibility and fine filament drawing (under 11μm) require slower output speeds, affecting the overall cost.
Operating since 2015 in Jiangxi, China Beihai Group utilizes local, chemically consistent basalt ore. We integrate filament drawing, custom twisting, and multi-axial weaving in a single facility. This unified workflow ensures raw material quality and lowers freight overhead, enabling us to offer highly competitive pricing compared to Western alternatives.
Basalt roving acts as a mid-to-high range bridge. It provides much higher tensile strength and chemical resistance than traditional E-glass at a lower cost than premium carbon fiber. Unlike carbon, basalt is non-conductive, does not corrode when exposed to concrete or salt water, and maintains its mechanical integrity under high heat (up to 820°C).
We supply continuous filament roving featuring multi-compatible silane sizing agents. They can be formulated for high compatibility with epoxy (EP), vinyl ester (VE), phenolic (PF), unsaturated polyester (UP), and polyurethane (PU) resin matrices, ensuring strong interfacial bonding and shear strength.
Standard custom weaving runs require 15 to 25 days depending on tooling and loom scheduling. We pack our basalt products in sealed moisture-barrier bags on robust fumigated wood pallets. This prevents humidity absorption during ocean transport, ensuring the fibers arrive dry and ready for resin infusion.
