Explore our top-tier basalt products designed to replace traditional reinforcement options with enhanced chemical stability and high tensile properties.
Extruded directly from selected volcanic basalt rocks melted at temperatures exceeding 1450°C, basalt mineral chopped fibers are produced through rapid melt drawing without toxic chemical additions. This structural dynamic produces a green, durable product that exhibits outstanding tensile performance, excellent anti-corrosion behavior, and natural resistance to acid and alkaline degradation.
Compared to conventional E-glass or synthetic options, basalt chopped strands possess an exceptional thermal envelope (-260°C to +820°C) and an elastic modulus that surpasses E-glass by up to 20%. As a key additive in concrete matrixes, high-temperature friction components, and composite structures, basalt mineral chopped strands effectively mitigate thermal stress crack propagation, structural fatigue, and internal concrete matrix degradation.

From bridge defenses to aerospace insulation, basalt fiber's physical characteristics provide structural upgrades across demanding operational conditions.
Used in foundation works, concrete facades, and high-stress building components. Basalt chopped strand reinforcement increases flexural strength, controls shrinkage cracks, and resists environmental weathering over long service lifespans.
Ideal for fabricating engine cowlings, internal partition walls, and soundproofing layers. Basalt fiber provides critical thermal protection and weight savings, enhancing overall aircraft efficiency and safety.
Our research teams optimize continuous basalt filaments for rocket booster shielding, thermal reentry layers, and exhaust components, where structural integrity must remain stable under extreme temperature spikes.
Adding basalt strands directly into a concrete wet mix improves tensile properties and impact resistance. This structural change suppresses micro-cracks and protects against internal chemical decay in coastal engineering.
Basalt fiber is widely utilized to replace heavy steel components and synthetic plastics. Its thermal stability makes it well-suited for brake pads, exhaust mufflers, underbody panels, and bumper systems.
High strength, environmental durability, and impact absorption make basalt fiber jackets ideal for protecting concrete bridge columns from water currents, marine salt ingress, and vehicular impact.
Basalt's resistance to hydrocarbons and hot acids protects transport pipelines, chemical storage vessels, and refinery facilities from corrosion and leak pathways.
Designed for hulls, offshore decks, and underwater structural repairs. Marine environments require the non-corrosive and biological resistance properties provided by basalt fiber composite overlays.

Unlike E-glass, which decomposes inside the highly alkaline environment of curing concrete (pH 12–13), basalt chopped strands exhibit strong chemical resistance due to their stable chemical composition and high silica/alumina balance. They prevent alkali-silica reaction (ASR) failure, maintaining concrete reinforcement integrity over decadal design cycles.
For standard concrete mixtures, a typical addition of 2.0 to 4.5 kg of basalt chopped strands per cubic meter provides significant crack control and tensile enhancement. In asphalt applications, addition rates of 0.3% to 0.5% by weight of the aggregate mix are recommended to increase fatigue resistance and reduce high-temperature rutting.
Basalt fibers retain structural properties at extreme cryogenic levels (-260°C) without embrittlement, and sustain operation up to 820°C. They do not drip, support combustion, or release toxic gases during thermal exposure, outperforming carbon and glass composites under severe fire ratings.
Yes, our continuous basalt strands, rovings, and rebar lines are produced under ISO 9001 quality controls. They comply with ASTM D8005, ASTM D7913, and EN standards for high-strength composite systems, ensuring acceptance in public works and infrastructure projects worldwide.
