Direct Factory AccessFounded in 2015 and strategically nestled in Jiujiang, Jiangxi Province, China Beihai Group operates as a certified high-tech enterprise dedicated specifically to the scientific R&D, industrial production, and macro-distribution of premium-performance basalt continuous fibers. Our facility integrates proprietary green melting technology alongside heavy industrial equipment engineering, making us a key anchor manufacturer and trusted supplier globally.
By transforming raw natural basalt rocks via high-temperature electric furnace melting, we create high-strength alternatives to conventional fiberglass and high-cost carbon composites. Our operational framework addresses strict industrial supply metrics, providing high-integrity building and aerospace materials tailored for hostile operational environments.
Understanding the molecular transition of natural igneous basalt rock into high-performance continuous structural roving filaments.
The manufacturing process begins by selecting quarry-grade volcanic basalt stone featuring optimal mineral distributions (plagioclase, olivine, and pyroxene). Constant chemical checks guarantee silicon dioxide (SiO2) is maintained above 46% to balance flow properties inside the furnace.
Washed basalt rocks are introduced into proprietary gas-oxygen and electric-melting refractory furnace configurations. Melted cleanly at temperatures up to 1500°C, the fluid rock requires precise viscosimetric tracking to maintain consistent drawing parameters.
Melted volcanic lava flows smoothly through highly calibrated bushings made from robust Platinum-Rhodium (Pt-Rh) alloy containing 200 to 2400 high-precision orifices. Under precise micro-pressures, the molten raw material forms highly uniform structural micro-filaments (9µm to 22µm).
Immediately after high-velocity cooling jets quench the fibers, chemical sizing agents are applied. These tailored organosilane compounds ensure robust structural bonding with matrix resins (epoxy, polyester, vinyl ester, or concrete binder complexes).
The individual finished filaments are aligned under steady tension profiles to form dense, structural untwisted direct rovings or assembled rovings. Automatic control winders packages the fiber roving into structured, robust transport cylindrical packages.
Completed direct roving units undergo rigorous verification steps, checking break tension, density index (Tex), moisture ratios, and resin compatibility metrics in compliance with international ISO 9001 and ASTM manufacturing procedures.
Comparing high-performance continuous basalt fiber roving with glass and steel highlights its significant structural advantages. Because it offers high chemical durability, corrosion resistance, and works across broad temperature margins, our continuous roving is ideal for complex marine and infrastructure reinforcement challenges.

While carbon fiber offers higher absolute modulus, basalt roving provides exceptionally balanced properties at a fraction of the cost. It delivers excellent impact tolerance, broad thermal capability, complete electrical insulation, and superior alkaline stability, making it highly cost-effective for civil infrastructure and heavy industrial applications.
We maintain close control by sourcing high-purity volcanic basalt rock characterized by uniform chemical composition (e.g., specific iron oxide ratios). Our automated gas-electric melting furnaces run continuously at 1450°C to 1500°C under computer monitoring, preventing viscosity changes that could compromise the physical integrity of the extruded filaments.
We apply advanced silane-based sizing solutions configured for quick and thorough wetting in specific matrix systems. Depending on your needs, we offer sizings optimized for epoxy (EP), vinyl ester (VE), unsaturated polyester (UP), polyurethane (PU), and cementitious binders.
Yes, basalt fiber exhibits far higher resistance to alkaline environments than standard E-glass. When cast directly into concrete, it resists alkali attack, preserving structural reinforcement without degrading like glass or rusting like steel rebars.
