Industrial sectors are rapidly shifting from conventional, energy-intensive materials to advanced, environmentally conscious alternatives. Continuous Basalt Fiber (CBF) represents a monumental paradigm shift. Derived directly from pure volcanic rock through high-temperature melting at 1450°C without any synthetic chemical additives, basalt fiber presents a naturally green, highly stable inorganic compound.
When evaluated against classic reinforcement composites like E-glass and carbon fibers, basalt fiber exhibits a unique profile. While carbon fiber offers ultra-high stiffness, its high production costs and carbon footprint make it less practical for massive civilian infrastructures. Conversely, standard fiberglass often degrades under harsh environmental conditions, especially in highly alkaline cement matrices. Basalt fiber strikes a perfect balance: offering mechanical characteristics close to carbon fiber at a price point comparable to premium E-glass, with superior resistance to acids, alkalis, heat, and moisture.
Significantly lower lifecycle maintenance costs. Eliminates the necessity for corrosion-resistant coatings or structural concrete repairs, yielding major capital savings over project lifetimes.
Manufactured with minimal raw-material refining and zero toxic byproducts. Basalt fibers contribute to lower structural carbon footprints, aligning directly with LEED and Green Star protocols.
Abundant global supply. Sourced directly from naturally occurring basalt basaltic deposits, ensuring highly stable raw material costs and reliable long-term procurement security.

Structural reinforcement constitutes a premier industrial application of our composite line. Traditional steel reinforcement bars (rebar) are highly vulnerable to oxidation and chloride ingress, leading to internal concrete cracking, structural delamination, and costly repairs. Our high-performance Basalt Fiber Rebar is designed as a direct replacement.
With a specific gravity just 1/4 of structural steel, our basalt rebar vastly simplifies transportation and handling. Its absolute resistance to chemical degradation, combined with outstanding compatibility with portland cement and geo-polymers, guarantees a design life exceeding 100 years. For magnetic resonance imaging (MRI) structures, high-voltage transformer foundations, and chemical refinery slabs, our non-conductive rebars offer complete electromagnetic transparency, eliminating dangerous electrical induction and current leakage.




Continuous Basalt Fiber Roving serves as the primary building block for our downstream composite components. Sourced from high-purity mineral reserves, the basalt raw material is fed into computerized gas-electric furnaces, extruded through platinum-rhodium alloy bushings, and immediately coated with high-performance coupling agents.
Our roving and yarn configurations exhibit exceptional mechanical consistency, high sizing compatibility, and zero twist characteristics, making them perfect for pultrusion, filament winding, and automated weaving. Our continuous rovings are deeply integrated into manufacturing high-voltage insulative rods, composite utility poles, fiberglass-alternative marine hulls, and industrial gas cylinders.

To operate confidently in the highly regulated aerospace, civil engineering, and petrochemical industries, strict alignment with international quality management systems is mandatory. At China Beihai Group, our facilities strictly adhere to rigorous testing protocols to ensure physical consistency, chemical durability, and dimensional accuracy across every product batch.
Our products comply with critical international testing and design guides, including ASTM D7957 (Standard Specification for Solid Round Glass Fiber Reinforced Polymer Bars for Concrete Reinforcement), **ACI 440.1R** (Guide for the Design and Construction of Structural Concrete Reinforced with FRP Bars), and **ISO 9001:2015** quality standards. This ensures that every basalt rebar, fabric, and roving meets strict engineering limits under extreme environments.





One of China Beihai's signature competencies is the customization of chemical sizing (coupling agents) applied to our continuous basalt fibers during the drawing process. Fiber-to-matrix interfacial adhesion is the single most critical factor in deciding composite shear strength and long-term durability.
We formulate tailored chemical sizes to match specific thermosetting and thermoplastic resin matrices, including:
Additionally, we support local mechanical validation, providing pre-engineered physical coupon testing reports, CAD design templates, and material data files to ensure seamless integration into structural designs.
As global industries transition toward zero-carbon and intelligent manufacturing, China Beihai Group is actively shaping the technological roadmap for basalt fiber materials over the next decade.
In our pursuit of zero-carbon basalt composites, our team is researching clean energy solutions. By moving from natural gas furnaces to electric-arc furnaces powered by wind energy, we aim to decrease the carbon footprint of basalt continuous fiber production by over 40% by 2028.
Our laboratory is pioneering the integration of carbon nanotubes (CNTs) and graphene oxide inside fiber sizing chemicals. This nanoscale modification improves interfacial shear strength (IFSS) by 35%, boosting dynamic impact performance for automotive components.
By incorporating micro-fine conductive wire cores within basalt fiber ropes, we are developing smart rebar systems. These sensors monitor structural integrity, detecting internal concrete cracks and stresses in bridges and high-speed rail lines in real-time.
Professional structural engineers and composite designers often have detailed questions regarding physical performance limits. Here are authoritative answers compiled by our R&D engineering division.
Unlike standard glass fiber, which experiences rapid structural loss due to alkali silica reactions (ASR), continuous basalt fiber possesses high chemical stability due to its mineral composition (especially high silica and alumina ratios). In addition, China Beihai coats its basalt fibers with a protective alkali-resistant sizing that prevents moisture penetration. For high-performance concretes, we recommend using basalt fibers with specialized sizing that forms an excellent barrier against high-pH concrete environments.
Basalt Fiber Reinforced Polymer (BFRP) rebar has a thermal expansion coefficient closely matching that of concrete (ranging between 9.0 to 12.0 × 10^-6/°C). This matching expansion profile significantly reduces internal micro-stresses and concrete delamination during extreme temperature shifts. This characteristic makes it highly suitable for outdoor concrete slabs, bridge decks, and high-temperature industrial flooring.
Yes. Because basalt continuous fibers are composed of pure, naturally occurring volcanic rock without toxic additives, they can be crushed, melted down, or reprocessed back into short chopped strands or structural aggregates. This circular lifecycle represents a major advantage over composite materials that are difficult to recycle at their end-of-life.
Basalt continuous fiber is non-magnetic and chemically inert, offering exceptional electromagnetic transparency. It does not induce electrical currents or interfere with high-frequency signals. This unique characteristic makes it highly suitable for constructing MRI medical diagnostics rooms, telecommunication radar structures, and high-voltage power substation foundations.
For custom roving sizing formulations or specific rebar cross-sections, our standard manufacturing lead time ranges between 15 to 25 days. Backed by our modern, high-capacity production facility in Jiangxi Province, we maintain stable production cycles and consistent quality control to ensure dependable global shipments.
The rapid rise of automated robotics and high-precision equipment on modern factory floors demands advanced mechanical supports that are exceptionally strong, lightweight, and vibration-resistant.
In this landscape, continuous basalt fiber composites are emerging as a core solution. Through advanced research, China Beihai Group continues to expand the capabilities of basalt continuous fiber, introducing new options for high-performance engineering projects worldwide.
