Engineered for extreme thermal thresholds, high alkali resilience, and structural longevity. Explore our foundational basalt products.
High-Temperature Basalt Mat products represent the cutting edge of mineral-based material science. Derived from igneous volcanic rock melted at temperatures exceeding 1450°C to 1600°C, continuous basalt fibers are manufactured through single-component extrusion, eliminating the need for synthetic chemical modifiers. This preserves the natural, high-strength characteristics of volcanic minerals, offering thermal, chemical, and electrical performance far superior to conventional E-glass fiber.
Unlike traditional ceramic fibers that pose health hazards due to respirable particulate structures, or organic polymer meshes that release noxious smoke upon thermal degradation, basalt mats are environmentally inert, structurally stable, and non-carcinogenic. With a continuous working temperature envelope ranging from -260°C to +700°C (and short-term spikes up to +980°C), this material provides a robust thermal barrier for aerospace engine cowlings, industrial smelting exhaust systems, EV battery fire walls, and building insulation.

Basalt fiber is ideal for your engineering projects. Its high strength, corrosion resistance and lightweight properties allow it to easily solve a variety of challenges.
In buildings, bridges, roads and other infrastructure projects, basalt fibers demonstrate outstanding performance, extending structural life and reducing maintenance costs. Choose basalt fiber, choose reliability and durability.
Because continuous basalt fibers do not degrade in alkaline environments, they serve as the premier replacement for steel mesh and E-glass in reinforced concrete structures exposed to marine splash zones, chemical storage areas, and subterranean tunnels. The mechanical cohesion between our needle-punched matrices and common industrial resins (such as epoxy, vinyl ester, and polyurethane) guarantees maximum structural integrity under continuous load parameters.
Basalt fiber rebar is a high-strength alternative to traditional steel bars and is used in a wide range of applications for reinforcing concrete structures in various fields, and its excellent performance makes it ideal for a variety of construction applications such as bridges, highways, buildings and other infrastructure projects.
Engineered using high-strength basalt continuous filaments bound with thermosetting resins, our rebar line features zero induction, zero magnetic signal interference, and complete resistance to sodium hydroxide, hydrochloric acid, and marine saltwater deterioration. It reduces concrete cover requirements and extends the lifespan of infrastructures to over 100 years.

An authoritative engineering analysis detailing the role of continuous basalt minerals in next-generation structural matrices.
China hosts some of the world's most massive deposits of high-grade, low-iron volcanic basalt rock, presenting a critical advantage for raw material sourcing. For decades, the primary hurdle in continuous basalt fiber production has been chemical composition fluctuation within the quarry. Diverse mineral veins shift the concentration of silica and iron, causing thread breakage inside platinum-rhodium bushings.

As multi-national construction firms and automotive OEMs transition to circular economy platforms, material selection relies heavily on Life Cycle Assessment (LCA) metrics. Basalt fiber offers an exceptionally low carbon footprint compared to carbon fiber or specialty metals. Processing igneous basalt stone requires only crushing, washing, and melting — completely bypassing the highly toxic polyacrylonitrile (PAN) precursor pathways of carbon fiber synthesis.
Additionally, basalt needle mats are fully recyclable, non-toxic, and simple to re-process into secondary structural aggregates. Procurement executives seeking compatibility with green building rating systems, such as LEED or BREEAM, find that incorporating China Beihai’s continuous basalt products significantly accelerates their ESG compliance.
One of the most critical current engineering trends is the adoption of basalt needle mats inside EV battery packs. In the event of a lithium-ion battery cell failure, localized temperatures can instantly spike to over 900°C, inducing a thermal runaway cascade. Our high-temperature resistant needle mats serve as an exceptional thermal barrier. Wrapped around battery cells, they block heat transmission and prevent flame propagation without introducing excess weight or compromising battery energy density.
Expert engineering answers to your technical questions regarding continuous basalt fiber applications.
Our continuous basalt fiber needle mats are certified to withstand a continuous working temperature of -260°C to +700°C. For temporary thermal excursions, such as flash fires or industrial exhaust spikes, the material can withstand peak thermal exposures up to +980°C without melting or releasing toxic outgassing.
Basalt fiber excels in mechanical and chemical properties compared to E-glass. It provides 15–20% higher tensile strength, 30% higher elastic modulus, and exceptional alkaline resistance. It does not degrade when exposed to the high-pH environment of wet concrete, making it the premier choice for structural rebar and reinforcing mesh.
Our high-temperature needle mats are manufactured using pure mechanical needle punching without any chemical binders or sizing polymers. This ensures that the mat remains 100% fire-resistant (Class A1) and will not release smoke or toxic vapors when exposed to high temperatures.
Our surfacing tissue mats and continuous fabrics are treated with custom silane sizing agents. They demonstrate excellent chemical compatibility and adhesion with epoxy, vinyl ester, polyester, and polyurethane thermosetting resins.
Traditional steel rebar rusts when moisture, salt, and oxygen penetrate the concrete over time, causing structural cracking and concrete spalling. Basalt fiber rebar is completely corrosion-proof and impervious to salt sprays, acid rain, and alkaline compounds. By eliminating rust-related degradation, basalt rebar can extend the operational life of bridges, marine docks, and highways to over 100 years.
