Explore our foundational range of premium volcanic-derived continuous fiber products engineered for ultimate thermal resistance, tensile strength, and structural integrity.
Pioneering the domestic high-performance continuous basalt fiber ecosystem.
Founded in 2015 in Jiujiang, Jiangxi Province, China Beihai has emerged as a premier high-tech enterprise at the forefront of engineering, researching, developing, and manufacturing basalt continuous fiber raw materials and finished high-performance components. Our integrated state-of-the-art facility commands proprietary manufacturing equipment architectures that lead the domestic industrial basalt fiber ecosystem.
By leveraging pristine natural volcanic basalt stone and processing it through automated high-precision furnace drawing processes, we convert raw minerals into extremely strong continuous filaments. These structural building blocks form the foundation of our extensive portfolio, spanning customized structural reinforcement sleeves, alkali-resistant concrete rebars, thermal insulation tissues, and woven composite meshes.
Technical performance metrics, structural comparisons, and environmental mechanics.
Modern engineering requires components that withstand physical environments too harsh for traditional glass fiber (E-glass) and too cost-prohibitive for carbon fiber. This is where Basalt Continuous Fiber becomes an essential structural standard. Derived directly from dense igneous volcanic rock melting at 1450°C, the resulting continuous basalt fiber presents a single-ingredient silicate chemistry. It has zero chemical additives, making it intrinsically non-toxic, non-carcinogenic, and 100% recyclable.
When braided into Basalt Fiber Sleeves, these materials function as robust thermal, electrical, and mechanical protection shields. Because basalt possesses superior resistance to concentrated alkaline exposure, acidic degradation, and physical friction compared to silica and glass fibers, these sleeves are widely adopted in major industries. From aerospace wiring insulation to custom petrochemical high-pressure transport pipelines, basalt is the optimal material choice.
"Continuous basalt fibers present an exceptional tensile elastic modulus exceeding 85-95 GPa. This structural stiffness, paired with low density and a wider thermal operating range (-260°C to +820°C), makes braided basalt sleeving the absolute baseline standard for heavy industrial thermal protection."
| Performance Metrics | Continuous Basalt Fiber | E-Glass Fiber | Carbon Fiber (Standard) |
|---|---|---|---|
| Tensile Strength (MPa) | 3000 – 4800 | 1500 – 2500 | 3500 – 5000 |
| Elastic Modulus (GPa) | 85 – 95 | 69 – 72 | 230 – 240 |
| Max Thermal Limit (°C) | 820°C (Up to 1200°C short-term) | 550°C | 500°C (Oxidizing Environment) |
| Alkali & Acid Resistance | Excellent (Alkali loss < 2%) | Poor to Moderate | Excellent |
| Eco-Footprint & Recyclability | 100% Natural, Zero Carbon Output | Synthetic, Medium Carbon Output | Energy Intensive Process |
The global demand for high-strength composite infrastructure materials is growing. Industrial markets are rapidly shifting toward high-temperature basalt braided sleeves and alkali-resistant mesh systems. Industry regulations in the European Union and North America now prioritize materials with minimal embodied energy. Basalt meets these green-building guidelines perfectly because processing volcanic stone uses significantly less energy than manufacturing glass fiber or carbon fiber composites.
Today, the commercial landscape for basalt continuous fibers is rapidly expanding. Emerging regions are widely integrating basalt rebars and sleeves in civil marine defenses, coastal bridges, and smart grid power transmission lines. Because basalt is naturally non-conductive, it acts as an insulating shield for high-voltage cables, protecting them from electromagnetic interference and physical wear.

Advancing sizing chemistry, automated continuous drawing, and hybrid composite protection systems.
The performance of any continuous basalt composite is defined by the interfacial shear strength (IFSS) between the fiber and the polymer matrix. China Beihai is actively engineering next-generation sizing chemistry. By applying specialized silane coupling agents combined with custom emulsions, we match the surface properties of our basalt fibers directly to high-density epoxy, vinyl ester, and complex cement systems.
As advanced computing systems, defense electronics, and aerospace vehicles demand more effective thermal protection, our development roadmap focuses on producing hybrid smart sleeving materials. By blending continuous basalt yarns with specialized aramid and metal filaments, we are designing hybrid sleeves that combine excellent thermal insulation with active electromagnetic shielding. These upcoming products will help safeguard aerospace controls and critical sensors from extreme heat and signal interference.
