Basalt fiber is a high-performance inorganic material manufactured from extremely fine fibers of basalt, which is composed of the minerals plagioclase, pyroxene, and olivine. It is similar to fiberglass, having better physicochemical properties than glass fiber, but being significantly more affordable than carbon fiber. Used as a fireproof textile in the aerospace and automotive industries, it can also be used as a composite to produce a wide range of products including rebar and mesh.
The global shift toward "Green Building" and "Decarbonization" is driving the basalt market. As an 100% natural inert material with no toxic reaction with air or water, it is becoming the preferred replacement for steel rebar in coastal infrastructure to prevent corrosion. Future trends focus on hybridization—combining basalt with carbon fiber to balance cost and modulus.
Current demand is surging in North America (for seismic-resistant bridges) and the Middle East (for petrochemical pipe reinforcement). Procurement officers are increasingly moving away from traditional glass fiber (E-glass) due to basalt's superior Alkali Resistance and Operating Temperature Range (-269°C to +700°C).
China Beihai was founded in 2015 and is located in Jiujiang, Jiangxi Province. As a high-tech enterprise, we focus on the research, development, production, and sales of high-performance basalt continuous fiber and specialized manufacturing equipment. We are recognized as a leading enterprise in the domestic basalt fiber industry.
At China Beihai group, we specialize in the production of a wide range of products including basalt fiber mat (Basalt fiber chopped strand mat, Basalt fiber cloth), basalt fiber roving, basalt fiber yarn, basalt fiber chopped strands, and basalt fiber products like Basalt Fiber rebar, sleeves, and tape.
We are dedicated to delivering high-quality, sustainable solutions for industries such as construction, geotechnical engineering, and manufacturing. With a commitment to innovation and excellence, we strive to cater to the unique requirements of our clients.
Choosing China Beihai means partnering with a thought-leader in basalt technology. Our commitment to quality, innovation, and sustainability ensures best-in-class solutions backed by industry expertise and reliability.
Basalt Rebar is 4x lighter than steel and provides 2.5x the tensile strength. Ideal for bridges and highways where salt-spray corrosion is a concern. It extends structural life by over 50 years while reducing maintenance costs.
Utilizing basalt fiber tissue mats for engine thermal protection and aircraft wing components. For EVs, basalt composites provide lightweighting benefits that directly translate to increased battery range and safety.
Superior chemical resistance makes basalt fiber the ideal choice for underground piping, storage tanks, and high-temperature filtration systems where acids and alkalis would degrade traditional materials.
Our production facilities adhere to ISO 9001:2015 standards. Every batch of roving and rebar undergoes rigorous testing for tensile strength, modulus of elasticity, and thermal conductivity to ensure global compliance (ASTM/CE).
As drones slice through the sky to monitor wildfires, and intelligent robots execute repetitive tasks with precision on the factory floor, the efficient operation of this smart equipment is often underpinned by a "hardcore support"—high-performance basalt composites. Our latest research team has made it possible to use basalt fibers in the manufacture of spacecraft shell materials and thermal protection systems.
