Costa Rica stands as a global beacon for sustainable development, ecological conservation, and carbon neutrality. Driven by the Plan Nacional de Descarbonización (National Decarbonization Plan 2018-2050), the nation's construction and engineering sectors are undergoing a massive transition from high-embodied-carbon materials (such as standard structural steel and synthetic polymers) to carbon-friendly, mineral-based alternatives. However, the geophysical challenges of Central America are severe.
The combination of extreme tropical relative humidity, highly corrosive coastal environments (affecting key logistics gateways such as Moín, Limón, and Caldera), and active tectonic fault lines (seismic zones 3 and 4) creates a demanding environment for physical structures. Traditional reinforced concrete structures are highly vulnerable to steel carbonation and chloride-induced rust, leading to concrete spalling and early mechanical degradation. This is where continuous basalt fiber (CBF) provides a highly effective solution.
Extruded directly from single-component volcanic basalt ore, our basalt products are naturally immune to rust, organic breakdown, and chemical attack. By replacing typical steel rebars and fiberglass sheets with volcanic basalt alternatives, Costa Rican infrastructure gains longer lifespans, lighter weight, and excellent seismic damping qualities, all while meeting strict carbon reduction targets.
Founded in 2015 and headquartered in Jiujiang, Jiangxi Province, China Beihai Group is a high-tech pioneer specializing in the research, development, production, and sales of high-performance basalt continuous fibers. We also manufacture advanced processing equipment, positioning us as an industry leader.
Utilizing high-precision multi-crucible drawing technology and proprietary sizing formulas, China Beihai converts natural raw volcanic rock into high-tensile continuous micro-filaments. Our production plant operates under strict ISO 9001 and ISO 14001 certifications, ensuring that every batch of yarn, rebar, and mesh delivered to Latin America meets rigorous ASTM and European specifications.
Our commitment goes beyond traditional manufacturing. We work closely with municipal planners, engineering consultancies, and marine contractors worldwide, offering full-scale custom pultrusion roving, structural meshes, and high-temp sleeves to support global decarbonization efforts.

How continuous basalt fiber products solve critical structural and material challenges in demanding environments.
Replacing traditional carbon-intensive reinforcement with basalt rebars and chopped strands in concrete, wall boards, and mortars. This significantly reduces thermal bridging and increases fire resistance.
Provides complete protection against sea salt and humidity. Our basalt rebars and marine matrices prevent decay in seawalls, bridge piers, and harbor berths exposed to constant splash zones.
High thermal stability allows basalt fibers to operate efficiently at high temperatures. Perfect for insulating steam pipelines, electrical systems, and geothermal facilities.
Our chopped basalt fibers significantly improve dynamic shear strength and impact energy absorption. This reduces micro-cracking in seismic-resistant structural foundations.




The performance of continuous basalt fiber depends on raw material selection and temperature control during production. Our manufacturing process at Jiujiang, Jiangxi, follows a strict technical route:
1. Mineral Selection & Preparation: We source natural volcanic basalt rock with high silica (SiO₂) and alumina (Al₂O₃) content, maintaining low iron levels. This chemical composition is essential for producing high-tensile, corrosion-resistant fibers.
2. High-Temperature Melting: The basalt rock is crushed and melted in our gas-fired recuperative furnaces at temperatures reaching 1450°C. No chemical additives or pigments are used, ensuring a 100% natural, eco-friendly melting process.
3. Platinum-Rhodium Bushing Drawing: The molten basalt is extruded through high-precision platinum-rhodium alloy bushing plates, producing continuous micro-filaments with diameters ranging from 9 to 22 micrometers.
4. Specialized Sizing Application: A custom silane coupling agent is applied immediately to protect the fiber surface and optimize bonding with epoxy, vinyl ester, or concrete matrix systems.
Navigating the transition from traditional steel to basalt reinforcement requires compliance with structural standards and local regulations. China Beihai provides comprehensive support to align with Costa Rica's engineering codes, such as the Código Sísmico de Costa Rica (CSCR).
Our structural basalt rebars comply with ASTM D7957/D7957M, the international standard for solid round glass-fiber-reinforced polymer and basalt bars for concrete reinforcement. This compliance simplifies approval processes with local municipalities, MOPT (Ministerio de Obras Públicas y Transportes), and CFIA (Colegio Federado de Ingenieros y de Arquitectos).
Our logistics team handles export and import clearances from Jiujiang to Puerto Limón or Puerto Caldera, helping clients optimize shipping costs and lead times.
