Founded in 2015 and situated in the industrial manufacturing hub of Jiujiang, Jiangxi Province, China Beihai Group has emerged as a vanguard enterprise in the development, formulation, and commercial-scale production of high-performance continuous basalt fiber and downstream performance composite products.
As a national recognized high-tech enterprise, we direct significant assets towards scientific research, operating state-of-the-art furnace draw assemblies, and custom sizing line designs. We supply critical mechanical raw materials to industries demanding unmatched performance, chemical stability, and eco-sustainable profiles. Our dedication guarantees continuous industrial-scale output backed by stringent quality controls.
We deliver customized molecular performance, resilient supply chains, and absolute structural reliability for infrastructural challenges.
At China Beihai Group, we specialize in the advanced engineering of a complete suite of continuous basalt composite solutions. Our structural matrix components include basalt fiber chopped strands, high-tensile basalt roving, specialized basalt fiber yarn, multi-axial fabrics, high-temperature geogrids, structural rebar profiles, and fireproof braided sleeves. All variants are formulated to yield enhanced matrix adhesion and chemical resilience.
We govern the entire supply cycle from single-source raw basalt rock excavation to multi-nozzle platinum-rhodium bushing thermal draw processes. Operating strict QA guidelines across our automated processing infrastructure, we satisfy precise sizing chemical requests (epoxy, vinyl ester, phenolic compatibility). Our engineers produce customized materials suited to harsh geotechnics, industrial concrete structures, and marine works.
Partnering with China Beihai means locking in a premier global continuous basalt supplier. Our large-scale industrial footprint in Jiangxi ensures reliable supply-volume security, removing cost volatility and dispatch delays. Backed by certified physical laboratory tracking, comprehensive international standard compliance (ISO, CE, ASTM), and rapid logistics dispatch, we are your long-term, visionary partner for high-strength composite systems.

Continuous Basalt Fiber (CBF) is unique among high-performance reinforcement fibers because of its single-ingredient mineral origin. Prepared from selected volcanic basalt flows with specific chemical configurations—primarily silicon dioxide (SiO₂), aluminum oxide (Al₂O₃), iron oxides (FeO/Fe₂O₃), calcium oxide (CaO), and magnesium oxide (MgO)—our manufacturing process involves melting the raw crushed basalt rock at precise temperatures ranging between 1450°C and 1500°C.
Unlike standard E-glass, where synthetic batching introduces raw material variances, the homogenous volcanic glass phase of pure basalt provides superior structural advantages. By maintaining exact temperature ranges inside our custom gas-fired recuperative furnaces, China Beihai Group ensures that the silicate melt transitions seamlessly into homogeneous glass fibers. This controlled cooling phase prevents early crystal growth (devitrification) and preserves outstanding mechanical properties, such as a high young's modulus and excellent tensile strength.
The performance of basalt fiber chopped strands in composite matrices—such as concrete matrices, bulk molding compounds (BMC), and sheet molding compounds (SMC)—depends heavily on interfacial shear strength (IFSS). The technology roadmap at China Beihai is centered around developing next-generation organofunctional silane coupling agents that form reliable chemical bridges between the inorganic basalt fiber surface and the surrounding polymer or mineral cement matrix.
Our R&D focuses on functional sizing designs tailored for various resin systems, including:
When selecting structural reinforcements, engineers look at physical characteristics, performance under stress, and cost-to-performance ratios. Basalt fiber sits in a highly competitive position between lower-tier glass fibers and expensive carbon fiber alternatives:
Operating from Jiujiang, Jiangxi, China Beihai Group runs an advanced Manufacturing Execution System (MES) integrated with Distributed Control Systems (DCS). This combination represents our China Factory 4.0 strategy. Real-time temperature control loops keep furnace temperatures within a tight ±1°C range. This level of control is essential for preventing structural defects in our continuous basalt filaments.
Our localized supply chain in Jiangxi Province offers a major strategic advantage. By sourcing raw basalt minerals directly from nearby quarries with certified geological characteristics, we insulate global procurement partners from regional logistics shocks and raw material shortages. Our fully integrated facility manages raw crushing, precision melting, drawing, sizing, and cutting under one roof. This configuration maintains production efficiency, reduces waste, and guarantees predictable lead times for major international orders.

Technical insights for engineering firms, quality inspectors, and procurement managers sourcing continuous basalt products.
Unlike E-glass fiber, which degrades in the alkaline environment of concrete (pH 12–13) due to silica dissolution, basalt fiber features high chemical stability. China Beihai Group applies a proprietary, alkali-resistant silane-sizing coating to our chopped strands. This treatment protects the fibers during the concrete curing process, maintaining structural integrity over time.
We use automated Distributed Control Systems (DCS) to monitor and adjust furnace temperatures within a ±1°C range. Combined with multi-nozzle platinum-rhodium alloy bushing draw systems, this maintains consistent filament diameters (typically 9µm to 22µm depending on spec) and uniform mechanical properties across every production run.
Procurement teams should specify: 1. Chop length (commonly 3mm, 6mm, 12mm, or 24mm); 2. Filament diameter (typically 13μm to 17μm for mechanical reinforcements); 3. Sizing chemistry compatibility (epoxy, vinyl ester, polyurethane, or hydrophilic cementitious sizing); and 4. Moisture content tolerances.
Basalt is an inherently fire-safe volcanic material. It maintains structural integrity across a wide temperature range (-260°C to +700°C) and has a melting point of approximately 1450°C. It does not release toxic smoke or gases, making it an excellent choice for aerospace, automotive exhaust systems, and fire protection barriers.
