Explore our industrial range of high-performance thermal boards, needled mats, and protective sleeves engineered directly for international infrastructure and advanced thermal insulation systems.
Founded in 2015 and based in Jiujiang, Jiangxi Province, China Beihai Group is an ISO-certified, high-tech enterprise dedicated to the research, advancement, and scaled manufacturing of high-performance basalt continuous fiber. By melting single-component natural volcanic basalt rock at high temperatures of 1450°C to 1500°C and drawing it through platinum-rhodium alloy bushing plates, we produce high-performance fibers that excel in hostile mechanical, acidic, alkaline, and thermal conditions.
Unlike traditional fiberglass or carbon fiber products, basalt continuous fibers represent a 100% natural, eco-friendly, and green engineering material. Thermal insulation blankets derived from our volcanic basalt exhibit unmatched stability over an extreme temperature range of -269°C to 980°C. They do not drip, combust, or release toxic smoke under open-flame contact, meeting the most demanding safety protocols of the building, marine, aerospace, and energy sectors.
Providing global procurement teams with highly validated basalt solutions that outpace competitive materials across critical structural parameters.
We supply a massive spectrum of basalt derivatives, including continuous roving, custom chopped strands, high-density needled mats, structural unidirectional fabrics, non-conductive rebar, and customizable heat insulation sleeves or tapes. Every product is refined to match stringent international engineering standards.
By controlling everything from the sorting of premium volcanic ore to advanced furnace melting and downstream weaving, we optimize performance at each stage. Our processes yield basalt fibers with high tensile strength, exceptional acid-alkali barrier capacities, and extreme heat containment thresholds.
Collaborating with China Beihai Group means partnering with a verified domestic basalt continuous fiber powerhouse. Backed by extensive laboratory facilities, automated double-bushing production configurations, and professional regulatory certifications, we guarantee premium quality and direct supply chain reliability.
Scientific comparison clearly establishes basalt continuous fiber as a superior class of engineering material, outperforming traditional glass and rockwool alternatives.

Continuous basalt fiber roving is a foundational structural element that reinforces engineering composite matrices. Its high tensile modulus and natural resistance to corrosion allow it to solve challenging industrial problems with ease.
Whether reinforcing heavy concrete elements, wrapping subterranean pipelines, protecting chemical storage chambers, or fabricating aerospace composite hulls, our basalt fibers offer reliable reinforcement, extending product lifespans while reducing maintenance cycles.
Unmatched Durability: Volcanic rock is highly stable. As a result, our continuous fiber materials do not rust, degrade, or corrode over time, even when exposed to harsh outdoor marine environments, high UV radiation, or concrete alkalinity.
Our high-performance thermal insulation blankets and composite solutions serve critical functions across diverse industries, offering reliable performance under tough operating conditions.
Non-combustible insulation barriers that stop flame propagation and optimize thermal performance in high-rise building envelopes.
Engine wraps, insulation blankets, and lightweight interior composites that isolate heat while reducing airframe weight.
Excellent performance under high-speed friction and high-heat loads. Ideal for spacecraft shell panels and propulsion insulation.
Basalt rebars and chopped fibers eliminate micro-cracking and rust-induced spalling in bridge piers, highways, and offshore harbors.
High-temperature silencer mats, brake lining reinforcement, exhaust insulation sleeves, and structural thermoplastic composites.
Impact-absorbing envelopes that protect concrete piers against collisions, freeze-thaw cracking, and marine salt ingress.
Wrap-around thermal blankets and insulation sleeves protect piping networks from chemical leaks and high-pressure steam damage.
Provides salt-spray proof insulation barriers on ships, offshore drilling platforms, and coastal retaining structures.
Our custom basalt fiber rebar is a high-performance alternative to traditional steel bars, specifically designed for concrete reinforcement in highly corrosive or electromagnetic environments.
Because basalt rebar is naturally non-conductive, rust-proof, and lightweight (just 1/4 the weight of steel rebar), it simplifies transport and installation logistics. It is the premier choice for MRI facility rooms, power substation infrastructure, and marine retaining walls where steel corrosion causes early structural failure.
Long-Term Value: Using basalt rebar in infrastructure projects significantly reduces repair and maintenance costs while extending the concrete service life to over 100 years.

Deep-dive research reveals how continuous basalt needle mats sustain stable thermal barriers at 980°C, providing exceptional protection for extreme industrial applications.
Read ArticleClear, direct answers to common questions asked by global procurement managers, engineering firms, and technical directors.
Continuous basalt fiber is drawn from pure, single-component volcanic basalt ore, whereas fiberglass is made by melting synthetic silica mixes with chemical additives. Basalt possesses a much higher operating thermal threshold (980°C vs 650°C), superior tensile strength (nearly double that of standard E-Glass), and outstanding resistance to acids and alkalis, making it ideal for tough industrial applications.
We use a specialized mechanical needle-punching process to physically lock continuous basalt fibers together, creating a dense thermal and acoustic barrier. Because we omit chemical glues or organic resins, our mats do not produce toxic gas, smoke, or dripping materials when exposed to open flames, ensuring complete safety in confined spaces.
Yes, basalt fiber rebar is completely non-conductive and non-magnetic. Traditional steel rebar can disrupt sensitive electromagnetic fields in MRI rooms, power grid stations, and laboratory setups. Basalt rebar solves this issue entirely while providing excellent alkali resistance and preventing rust-related concrete spalling.
Our Jiujiang production hub features advanced, automated multi-bushing drawing furnaces that enable continuous manufacturing. Combined with our strict raw material sorting and comprehensive logistics networks, we offer global partners dependable volume scale, stable pricing, and on-time international delivery.
