Continuous Basalt Fiber (CBF) is an elite green inorganic high-performance material manufactured through the single-component melt extrusion of volcanic basalt rock. Unlike traditional glass fibers that rely on composite chemical components, basalt yarns are 100% natural, formed exclusively from raw quarry deposits that undergo melting at temperatures ranging from 1450°C to 1500°C.
At a molecular scale, the structural strength of basalt fiber is derived from its high concentration of silicon dioxide (SiO₂) and aluminum oxide (Al₂O₃), combined with network modifiers like iron oxides (FeO and Fe₂O₃), magnesium oxide (MgO), and calcium oxide (CaO). When drawn through platinum-rhodium alloy bushing plates, this complex mineral melt forms incredibly smooth, highly cohesive filaments with diameters ranging from 9 to 22 micrometers.
Our specialized Basalt Fiber Woven Yarn leverages customized twist formulations (measured in turns per meter, or TPM), utilizing precise silane sizing agents. Sizing is a critical engineering component that acts as the interfacial bridge between the basalt surface and various matrix resins (epoxy, vinyl ester, polyester, and phenolic). This custom sizing prevents micro-fracturing during high-speed textile weaving, guaranteeing unmatched structural integrity for structural engineers and fabricators worldwide.
| Performance Characteristic | Continuous Basalt Yarn | E-Glass Fiber | Carbon Fiber (Standard) | Engineering Significance |
|---|---|---|---|---|
| Tensile Strength (MPa) | 2,800 - 4,800 | 2,000 - 3,400 | 3,500 - 5,000 | Superior structural loading capabilities over glass. |
| Elastic Modulus (GPa) | 85 - 110 | 72 - 76 | 230 - 290 | High stiffness-to-weight ratio for critical load-bearing. |
| Operating Temp Limit (°C) | -260 to +700 | -60 to +450 | Max 500 (in oxidizing env.) | Excellent performance in cryogenic and extreme heat systems. |
| Chemical / Acid / Alkali Resistance | Excellent (High pH & acid stable) | Poor in strong acids/bases | Excellent | Resists corrosion from saltwater, alkalis, and organic acids. |
| Eco-Footprint & Recyclability | 100% natural, fully recyclable | Difficult to re-process | Extremely difficult to recycle | Meets strict ISO 14001, ESG, and circular economy demands. |
Empowering modern infrastructure, defense, aviation, and energy sectors through elite volcanic material fabrication.
Founded in 2015 in Jiujiang, Jiangxi Province, China Beihai is a nationally certified high-tech enterprise focusing on the continuous research, development, and high-volume manufacture of high-performance continuous basalt fiber and its proprietary production equipment. Over the last decade, Beihai has emerged as an authoritative leader in China's basalt fiber industry, optimizing processing configurations from melt-spinning to specialized downstream weaving.
Our state-of-the-art manufacturing plants combine modern raw mineral processing, complex furnace controls, and automated multi-end twisting machinery. Operating out of highly advanced industrial zones, we generate thousands of metric tons of continuous basalt fiber products annually, exporting reliable, high-integrity composites to architectural, marine, defense, and automotive enterprises across the Americas, EU, APAC, and the Middle East.
By pioneering clean electric melting technologies and continuous filament precision winding, China Beihai ensures that our raw yarn offers highly consistent physical metrics. Every batch is certified for quality tracking, helping international buyers establish solid material sourcing safety nets.
We supply a robust and comprehensive range of structural basalt fiber solutions. Our specialized output includes **Basalt Fiber Mats** (chopped strand mats, woven cloths), **Basalt Fiber Roving**, highly engineered **Basalt Fiber Twisted Yarns**, **Basalt Fiber Chopped Strands**, and high-integrity construction reinforcing elements such as **Basalt Fiber Rebar**, protective sleeves, and high-temp wrap tapes.
We design, formulate, and manufacture custom continuous volcanic mineral compounds that resolve severe stress challenges. We bridge the gap between scientific engineering research and high-volume, reliable industrial output. Our specialized research teams focus on perfecting sizing chemistry to support advanced bonding with concrete matrices, structural epoxies, and architectural coatings.
Working with China Beihai means collaborating with a vertically integrated powerhouse. Our dedication to quality, zero-defect quality control, and strict ESG compliance ensures you receive superior, high-performing materials. We provide rapid pricing structures, optimized supply chain resilience, and experienced technical consultation to simplify complex international engineering procurement.

How our high-performing volcanic fiber solves physical engineering challenges in demanding operational environments.
Traditional steel reinforcement elements corrode when exposed to harsh winter salts, moisture, and chemical agents, leading to expensive concrete spalling. Basalt fiber rebar and basalt fiber reinforced concrete (BFRC) are completely immune to chemical weathering, acid action, and carbonation, significantly increasing the structural lifetime of highways, marine retaining walls, bridge piers, and architectural foundations.
Continuous basalt woven yarns are integrated into aircraft internal heat barriers, engine compartment shields, and aircraft structure skins. They provide thermal insulation and high vibration absorption, combined with high mechanical stiffness at a fraction of the weight of stainless steel or high-density glass composites.
Addressing strict emission mandates requires automotive manufacturers to optimize vehicle weight. Basalt fiber composites replace heavier steel components in engine heat blankets, under-body acoustic protection panels, and vehicle body frames, boosting structural performance, dampening vibration, and keeping fuel and energy consumption low.
Industrial transport pipelines endure aggressive chemicals, internal pressure, and highly abrasive geothermal liquids. Filament-wound basalt fiber reinforced epoxy pipes display unparalleled chemical stability, zero rust propagation, and a low coefficient of thermal expansion, preventing leakage hazards and reducing costly fluid handling down-time.
Aging public highway supports, columns, and marine piers are easily reinforced using high-tensile basalt unidirectional woven fabrics. Wrapped structural supports gain strong impact protection against ship or vehicle collisions, extreme fires, and continuous saltwater splashing, ensuring complete safety for regional transportation routes.
Continuous exposure to high marine moisture and salty ocean environments corrodes traditional structural components. Basalt yarn composites remain physically stable and robust in sub-sea cables, hulls, oil rigs, and deep-sea exploration equipment, ensuring lasting operations with minimal long-term maintenance requirements.
Leveraging advanced domestic mineral abundance, high automation, and deep logistical positioning.
At China Beihai Group, we have revolutionized traditional basalt processing by implementing a state-of-the-art **Factory 4.0** digital ecosystem. Our continuous melting furnaces are fitted with precision heat-control algorithms that maintain absolute thermodynamic equilibrium within ±0.5°C. This eliminates the risk of fiber crystallization and brittle strands, which are common issues in older-generation, manually operated mills.
Once drawn, the continuous filament is routed to modern automated twisting spindles that coordinate winding speed and dynamic tension in real time. This highly automated process reduces physical variations across batches, ensuring that every spool of twisted yarn displays uniform density and precise tex counts.
Our geographical location in Jiujiang, Jiangxi, provides exceptional logistical benefits. We are positioned near major high-purity volcanic basalt stone deposits, insulating our production lines from raw material shortages. Furthermore, with direct access to extensive railway connections and nearby deep-water river ports linked to Shanghai and Ningbo, we offer fast transit and container loading options, reducing global lead times by up to 25%.
