Founded in 2015 and located in Jiujiang, Jiangxi Province, China Beihai Group is an internationally acclaimed high-tech enterprise dedicated to the research, development, continuous processing, and distribution of premium basalt continuous fibers (ECF) and advanced composite production equipment.
As a key driver in China’s continuous volcanic basalt extrusion sector, we supply large-scale global structural projects with highly reliable solutions, including basalt fiber mat (chopped strand mats, woven cloths), rovings, twisted yarns, reinforcement rebars, high-temp sleeves, and insulation tapes.
Basalt Continuous Filament Braiding Yarns represent an unparalleled milestone in advanced materials science. Extruded at extreme volcanic processing temperatures exceeding 1450°C, these natural filaments exhibit zero organic decomposition, making them intrinsically superior to conventional glass fibers, aramid, and even carbon fiber under distinct operational environments. When global procurements evaluate braiding yarns for thermal shields, composite over-wrapping, or protective sleeves, they require a meticulous structural understanding of physical and chemical attributes.
To provide clear analytical utility to composite engineers and procurement officers, the table below highlights the performance parameters of basalt continuous filaments against other industry-standard technical reinforcing fibers:
| Physical Property | Basalt Continuous Fiber | E-Glass Fiber | Carbon Fiber (Standard Modulus) | Aramid (Kevlar 49) |
|---|---|---|---|---|
| Density (g/cm³) | 2.63 - 2.80 | 2.54 - 2.60 | 1.75 - 1.80 | 1.44 - 1.45 |
| Tensile Strength (MPa) | 3000 - 4500 | 2000 - 3400 | 3500 - 6000 | 2900 - 3600 |
| Tensile Modulus (GPa) | 85 - 115 | 72 - 76 | 230 - 290 | 112 - 130 |
| Max Operating Temp (°C) | -260 to +700 | -60 to +380 | Up to +500 (inert) | -196 to +250 |
| Alkali Resistance (pH 12+) | Excellent (High Retention) | Poor (Rapid Degradation) | Excellent | Moderate |
| Acoustic & Vibration Dampening | High Absorption Coeff. | Low-Medium | Low | High |
Industrial braiding yarns fabricated by China Beihai are engineered to withstand continuous thermomechanical loads. The chemical composition of the basalt raw material contains key ratios of silica (SiO₂), alumina (Al₂O₃), iron oxides (Fe₂O₃ + FeO), and calcium oxide (CaO). This unique chemical configuration prevents crystalline phase change up to 800°C, meaning the braided products retain their physical shape, elastic modulus, and structural integrity far longer than conventional materials under intense fire scenarios.
Traditional steel and E-Glass reinforcing networks suffer heavily when exposed to alkaline environments typical of freshly poured Portland concrete (pH ranges from 12.5 to 13.5) and marine saltwater. China Beihai's basalt fibers are optimized with special custom silane-based sizing agents. This results in high alkaline resistance retention, allowing our geogrid structures, chopped fibers, and reinforcement rebars to resist chemical attack and extend structural lifespans past 100 years without maintenance.
We specialize in the full production cycle of continuous basalt fiber mat, basalt continuous direct rovings, twisted braiding yarns, chopped strands, structural composite rebars, protective sleeves, and high-temp wrap tapes, precisely configured to dynamic chemical tolerances.
We deliver certified high-strength, sustainable volcanic fiber materials for key global industries, such as high-temperature petrochemical pipelines, modern geopolymer concrete, deep-sea marine engineering, and aerodynamic aerospace shields.

Purchasing continuous volcanic basalt fiber composites directly from a leading Chinese producer like China Beihai Group offers strategic advantages for international firms, encompassing processing raw material selection, high-tech extrusion stability, cost efficiency, and full compliance.
Our facility in Jiujiang, Jiangxi utilizes premium volcanic rocks with very low FeO content and optimum SiO₂ concentrations. This provides melting stability in multi-nozzle furnaces, resulting in consistent filament diameters and minimizing defects.
Unlike conventional manufacturers that buy third-party equipment, China Beihai designs and builds its own continuous basalt fiber furnaces and processing lines. This dual capability allows us to customize twisting configurations and yarn sizes seamlessly.
Volcanic basalt fibers are 100% natural, green, and completely recyclable. Our production process consumes significantly less energy than glass or carbon fiber manufacturing, making it an ideal choice for green building standards like LEED.
