Explore our core high-performance basalt range manufactured under strict ISO 9001 quality guidelines.
In the structural engineering and high-performance composites sectors, mechanical integrity is not open to compromise. Custom Basalt Fiber 12mm represents a breakthrough structural element, bridging the gap between high-cost carbon fibers and alkaline-vulnerable E-glass fibers. Extruded directly from naturally occurring, molten volcanic basalt rock at temperatures exceeding 1450°C, these 12mm chopped strands deliver a unique molecular structure characterized by exceptional high tensile strength, supreme chemical immunity, and zero-corrosion properties.
Unlike glass fibers that degrade in concrete's alkaline environment, basalt fiber is naturally inert. It prevents the Alkali-Silica Reaction (ASR), guaranteeing structural survival inside marine slabs and chemical containment units.
With a tensile strength ranging between 3000 to 4800 MPa—almost three times that of standard steel reinforcement—12mm basalt chopped strands mitigate micro-cracking during early-stage cement hydration.
Operating safely from -260°C to +700°C, 12mm basalt fiber acts as a crucial fire barrier, safeguarding high-stress applications such as aerospace heat insulation, petrochemical piping, and fireproof panels.
Founded in 2015 and strategically positioned in the industrial hub of Jiujiang, Jiangxi Province, China Beihai is a premier high-tech enterprise dedicated to the research, development, production, and worldwide sales of premium-grade, high-performance basalt continuous fibers. Our facility is not merely a production site; it is a specialized laboratory pushing the envelope in advanced materials formulation and equipment manufacturing.
As a domestic pioneer, we leverage state-of-the-art multi-electrode melting furnaces and proprietary sizing chemical agents. This allows us to customize 12mm chopped strand filaments down to the exact micron, optimizing compatibility with specialized resin formulations (epoxy, vinyl ester, polyurethane) or concrete matrices.
Procurement managers and technical directors face high pressure regarding raw material reliability, price fluctuation, and standard compliance. Working directly with China Beihai delivers the benefits of an optimized, integrated supply chain.
Jiujiang, Jiangxi sits close to high-purity basalt volcanic reserves. This localized proximity guarantees steady material intake, bypassing international supply shocks and maintaining price stability year-round.
Whether reinforcing acidic concrete or manufacturing aerospace laminates, our R&D team formulates specific organosilane coupling agents to match your precise matrix and processing constraints.
Through proprietary multi-nozzle platinum-rhodium alloy bushing technology, we operate high-yield continuous drawing processes that significantly cut energy waste, feeding savings directly back to you.

Read MoreFor advanced infrastructure, structural materials must conform to strict localized building codes and safety standards. China Beihai eliminates this regulatory stress by ensuring every batch of 12mm basalt fiber matches ASTM, EN, and ISO testing protocols.
Whether your project requires compliance with ASTM C1666 (for alkali-resistant glass and basalt fiber reinforced cement), ACI 440.1R guidelines, or European EN 15422 classifications, our test reports provide transparent, verified traceability. We maintain strategic alliances with regional engineering laboratories across Europe, North America, and Southeast Asia to offer direct on-site support, design consultations, and custom tensile certification verification.
Our continuous basalt fiber drawing systems and finished reinforcement products are certified by top international bureaus.
The structural adaptability of the 12mm cut length makes it ideal for complex mechanical composites and heavy-duty structural designs.
Widely deployed in structural foundation slabs, dry-mix mortars, and exterior wall plasters. 12mm chopped strands prevent shrinkage micro-cracks from merging into catastrophic macro-fissures.
Serving as structural reinforcement for fuselage insulation and interior cabin lining panels. Basalt offers high flame retardancy, zero toxic outgassing during combustion, and valuable weight savings.
Excellent for highway overlays, industrial warehouse flooring, and airport runways. Adding 12mm basalt fibers significantly boosts structural toughness and impact resistance.
Used in molded underbody shields, brake pads, and soundproofing needle mats. Basalt stands up to heat, reduces weight, and offers superior acoustic dampening compared to standard fiberglass.
Highly stable against saltwater corrosion and splash zone damage. Essential for marine piers, coastal seawalls, and structural splash barriers where steel rusts and degrades.
Provides critical mechanical reinforcement for storage tanks and chemical pipes. Acid and alkali resistant properties prevent leaks and extend structural service life.
The composite industry is undergoing a major shift. The demand for lightweight, high-performance, and environmentally friendly materials is driving growth. Basalt fiber fits this need perfectly, offering a 100% natural, single-ingredient green material with a low carbon footprint during extraction.
Unlike carbon fiber manufacturing, which relies on heavy petrochemical processes, basalt is made by melting volcanic rock in electric furnaces. This reduces production emissions. This clean profile makes basalt a preferred choice for modern LEED-certified developments.
As global infrastructure ages, steel-reinforced structures are showing signs of degradation due to salt exposure and weathering. Upgrading to basalt reinforcement rebars and using 12mm concrete mixes provides long-term corrosion resistance, extending service life while keeping maintenance costs low.
Detailed, expert-level technical answers addressing the key design and application questions from mechanical engineers and procurement directors.
At China Beihai Group, we develop diverse high-performance solutions including basalt fiber mat (chopped strand mat, cloth), basalt fiber roving, basalt fiber yarn, basalt fiber chopped strands, and finished structural components like basalt fiber rebar, sleeves, and industrial tape.
Our proprietary manufacturing system is engineered to handle variable component sizes, multi-axial yarn structures, and customizable tensile ratings. By selecting Beihai as your supplier, you secure a reliable engineering partner focused on quality, innovation, and long-term sustainability.
As smart systems like monitoring drones and automated factory robots transform modern industries, they require advanced structural materials. High-strength basalt fiber composite elements provide this vital support. With exceptional toughness, corrosion resistance, and thermal stability, basalt stands out as a reliable, high-performance engineering solution.
