We supply a highly engineered product portfolio including basalt fiber needled felt mats, plain and twill weave cloth, high-temperature sleeves, high-strength roving, twisted yarn, chopped strands for cement, and premium structural Basalt FRP Rebar. Our products are carefully chemically-treated to match distinct architectural and composite resin environments.
At China Beihai group, we focus on eco-friendly, carbon-negative mineral melting technologies to turn solid volcanic rock into high-tensile filament roving. From civil infrastructure and coastal seawall reinforcement to automotive lightweight components, we collaborate directly with contractors to deliver sustainable, non-corrosive concrete reinforcement structures.
Partnering with China Beihai means leveraging our robust manufacturing capacities, advanced continuous-filament bushing technology, and custom chemical sizing capabilities. Our commitment to high mechanical integrity, precise linear density (TEX) control, and strict QA protocols guarantees robust supply chain reliability for large-scale engineering builds.

In modern civil engineering, concrete structures face severe threats from environmental degradation, chemical attacks, and moisture infiltration. Traditional steel reinforcement (rebar), while physically strong, suffers from inevitable rusting, which expands inside the concrete, causes micro-cracking, and ultimately leads to catastrophic structural failures. This is where Continuous Basalt Fiber (CBF) Roving has emerged as the ultimate structural material.
Basalt is an igneous rock formed from the rapid cooling of magnesium-rich and iron-rich lava. By heating pure, carefully selected basalt stones to a molten state at 1450°C to 1500°C in specialized gas-fired or electrical furnaces, and drawing the liquid rock through platinum-rhodium alloy bushing plates, we produce micro-filaments ranging from 9 to 22 micrometers in diameter. These continuous filaments are then coated with specialized organosilane sizing agents and wound into high-performance roving packages.
Unlike glass fibers (which suffer from degradation in the highly alkaline environment of curing cement) and carbon fibers (which are highly conductive and expensive), basalt fiber roving occupies the optimal cost-performance balance. It possesses tensile strength superior to typical structural steel (up to 3x higher), an elastic modulus that integrates seamlessly with concrete matrices, and complete natural immunity to acidic, alkaline, and electrochemical rust reactions.
Our R&D division has spent a decade refining the compatibility profile of our roving. Depending on the construction application, we manufacture specialized roving variants:
Specially treated with epoxy, vinyl ester, or polyurethane-compatible chemical sizing. This ensures complete fiber wet-out and matrix impregnation during pultrusion processing, yielding high-strength structural profiles, structural beams, and non-magnetic Basalt FRP Rebar.
Designed with a medium-to-hard sizing system that delivers excellent mechanical chopping behavior, low static buildup, and exceptional dispersion characteristics when blended into structural dry-mix concrete, concrete mortars, or heavy asphalt coatings.
Continuous Basalt Fiber products excel in critical environments where traditional glass and steel fail. Our localized solutions satisfy strict parameters in municipal, aerospace, marine, and industrial sectors.
Ideal for architectural concrete panels, thermal insulation layers, fireproofing envelopes, and lightweight structural composites that replace hazardous asbestos and fiberglass.
Leveraging high strength-to-weight ratios to build non-flammable cabin panels, thermal protective ducting systems, and composite engine shielding components.
Tested in orbital thermal systems, high-altitude composite pressure vessels, and engine exhaust components requiring stable mechanical performance at continuous high heat.
Reinforcing marine piers, harbor walls, airport runways, and industrial flooring grids to totally eliminate electrochemical corrosion and structural cracking.
Extensively applied in structural heat shields, exhaust mufflers, composite break linings, and compression-molded bumper systems for weight reduction in EVs.
Providing high impact damping, mechanical strength, and chemical durability to isolate bridge columns from vehicle collisions, scour, and chemical deicers.
Building corrosion-immune composite pipe systems, refinery thermal insulation covers, and subterranean chemical storage tanks that isolate acids and fuels.
Impervious to saltwater corrosion; utilized in offshore drilling platforms, vessel hulls, coastal tetrapod reinforcement, and subsea defense structures.
Gain insights into how we transform continuous filaments into downstream heavy-duty construction elements with advanced pultrusion and curing methods.
In a volatile global economy, ensuring continuous raw material supply and price stability is critical for multi-year infrastructure builds. Sourcing basalt fiber roving from China Beihai guarantees access to a highly optimized industrial ecosystem that excels in three key areas:
Our raw material is sourced from select volcanic quarry sites across Southwest and Central China, characterized by exceptional chemical uniformity (high SiO₂ and Al₂O₃ content). This geographical resource guarantee means zero raw material bottlenecks.
Melting igneous stone is energy-intensive. Jiujiang, Jiangxi hosts state-of-the-art multi-combustion furnace configurations utilizing clean energy power grids and natural gas heat recovery. This cuts production emissions while reducing manufacturing costs.
Every spool of basalt fiber roving leaving our plant undergoes digital tension monitoring, sizing loss-on-ignition (LOI) verification, and moisture absorption testing in our certified laboratories, meeting both Chinese GB and international ASTM rules.
