China Beihai was founded in 2015 and is located in Jiujiang, Jiangxi Province. As a state-of-the-art technological enterprise, we focus on the research, design, production, and distribution of high-performance continuous basalt fiber (CBF) and advanced material manufacturing equipment. Through continuous optimization of kiln smelting processes, we stand as a premier innovator and supplier in the global basalt mineral materials industry.
Our raw volcanic rock is selected from pristine geological resources, processed in clean, low-emission melting chambers at 1450°C. By leveraging integrated local mineral reserves and combining technical development with strict ISO quality management, we guarantee consistent quality and high mechanical reliability for every batch we ship globally.
Continuous Basalt Fiber (CBF) is rapidly becoming the material of choice for demanding structural and thermal operations worldwide, outperforming traditional E-glass and providing a cost-effective alternative to carbon fiber.
At China Beihai group, we specialize in the production of a wide range of basalt-based products, including basalt fiber mat (Basalt fiber chopped strand mat, Basalt fiber cloth), basalt fiber roving, basalt fiber yarn, basalt fiber chopped strands, and specialized basalt fiber products (Basalt Fiber rebar, basalt fiber sleeves, and tape). Our products are designed to meet the diverse needs of various industries, providing high-quality solutions for our customers.
Choosing to work with China Beihai means collaborating with a premier manufacturer of basalt solutions. Our commitment to high quality, technological innovation, and structural durability sets us apart, ensuring our customers receive best-in-class performance for their infrastructure and engineering challenges.

Our continuous basalt fiber roving is wound dry without twist, ensuring quick resin wet-out, excellent chemical compatibility, and superior structural tensile capability during pultrusion and filament winding processes. Perfect for high-pressure pipes, composite gas cylinders, and architectural laminates.
For structural construction, basalt rebars offer a lightweight alternative that is 4 times lighter than steel. Their total immunity to rust makes them ideal for building docks, highway bridges, coastal bulkheads, and MRI hospital rooms where electromagnetic waves must pass without interference.

Read the Full Industry ReportA deep look at how geology, mineral processing, and thermal engineering define the high performance of China Beihai Continuous Basalt Fiber (CBF).
Unlike glass fiber, which relies on mixed chemical ingredients, basalt fiber is produced from a single raw material: volcanic basalt rock. The performance of the fiber depends heavily on the chemical composition of the quarried rock. At our Jiujiang manufacturing base in Jiangxi, China, we select volcanic basalt with a silica ($SiO_2$) content between 48% and 53% and an alumina ($Al_2O_3$) content of 13% to 17%.
Maintaining the balance of iron oxides ($Fe_2O_3$ and $FeO$) is critical. High iron concentrations provide excellent thermal protection and natural UV defense. By analyzing the rock using X-ray fluorescence (XRF) before smelting, we ensure the raw mineral feed meets strict standards, preventing crystalline defects during extrusion.
China Beihai is investing in three key technological initiatives:
Developing low-emission, hybrid combustion kilns to reduce carbon footprints and ensure precise heat control at 1450°C.
Customizing chemical sizing agents to improve fiber-to-resin bonding strength for epoxy, vinyl ester, and thermoplastic composites.
Implementing sensor-based real-time checks for filament diameter control, reducing defects to under 0.05% across production runs.
Find technical answers to common questions about basalt rock fiber specifications, design guidelines, and supply chain logistics.
Basalt fiber offers up to 30% higher tensile strength, a higher elastic modulus, and significantly better chemical stability under acidic and alkaline conditions. It also withstands higher operational temperatures (up to 700°C) than glass fiber, which degrades around 380°C.
Yes, especially in corrosive, high-humidity, and marine environments. Basalt rebar is immune to rust and chemical attack from salts, which prevents concrete cracking. It is also non-conductive, making it ideal for hospital MRI rooms, high-voltage power substations, and sensitive electronic facilities.
We source volcanic basalt from inspected quarries and analyze its composition before processing. Our manufacturing facility in Jiujiang, Jiangxi utilizes automated electric-boost gas furnaces to maintain a stable melt temperature. Every batch undergoes tensile, diameter, and sizing compatibility testing in our laboratory, complying with ISO 9001 and CE requirements.
Yes. We specialize in developing tailored sizing formulations that match the chemical properties of PP, PE, PA66, and TPU resins, ensuring excellent fiber dispersion and composite mechanical performance.
