Get Manufacturers QuotesIn the scope of modern infrastructure engineering, structural degradation due to internal reinforcement corrosion represents a massive fiscal and logistical challenge. Basalt Fiber Reinforced Polymer (BFRP) rebar, commonly labeled as the **basalt steel bar**, presents a definitive material paradigm shift. Continuous volcanic basalt rocks are superheated to 1450°C and processed via proprietary pultrusion nozzles to produce an anisotropic structure with an ultimate tensile capacity vastly eclipsing carbon steel.
Unlike steel, which relies on heavy carbon matrices susceptible to oxidation, China Basalt steel bar strength is built upon a continuous, non-crystalline silicate grid network. This molecular geometry is impervious to chloride attack and acidic concrete environments. Crucially, the tensile strength of a high-quality basalt steel bar ranges from **1100 MPa to 1400 MPa** (subject to structural diameter), which is **2.5 to 3 times stronger** than standard Grade 60 (420 MPa) steel.
By specifying BFRP rebar over steel, structural designers can drastically reduce the self-weight of reinforced concrete structures by up to 75%. This weight reduction diminishes the seismic mass of structural columns and yields immense logistical cost savings during transport and onsite structural handling.
| Mechanical Properties | BFRP Rebar (Beihai) | Carbon Steel Rebar | Structural Performance Benefit |
|---|---|---|---|
| Tensile Strength (MPa) | > 1200 MPa | 420 - 550 MPa | Vastly higher peak load capacity |
| Modulus of Elasticity (GPa) | 45 - 55 GPa | 200 GPa | Excellent elastic energy absorption |
| Density (g/cm³) | 1.9 - 2.1 | 7.85 | Lightweight handling (75% lower weight) |
| Corrosion Vulnerability | Absolutely Nil | Extremely High | Eliminates concrete spalling risks |
| Thermal Expansion Coefficient | Comparable to Concrete | Different from Concrete | Vastly reduced internal stress fractures |
| Electromagnetic Conductive | Non-conductive | Highly conductive | Ideal for MRI rooms & smart toll plazas |
Founded in **2015** in the industrial cluster of Jiujiang, Jiangxi Province, **China Beihai** is a state-certified high-tech enterprise dedicated to the research, development, and high-volume manufacture of premium basalt continuous fibers and proprietary processing machineries. Over the past decade, we have scaled our production infrastructure to emerge as the premier supplier of basalt steel bars, roving, mesh, and specialized composites.
Our factory operates cutting-edge electric furnace systems, yielding continuous filaments with highly precise diameter consistency. By controlling the raw basalt mineral melt dynamics, we ensure every batch of basalt fiber reinforcement meets stringent international criteria. Our global footprint covers direct supply channels across North America, Europe, Australia, and the Asia-Pacific region.
We manufacture advanced basalt fiber roving, high-temperature basalt fabrics, chopped strand cement additives, continuous yarn rovings, thermal mats, and high-tensile basalt steel bars (BFRP rebar).
We refine natural volcanic rock to deliver engineering materials that resist extreme temperatures, withstand heavy acids or alkalis, and offer long-term durability in challenging concrete projects.
Our ISO-certified manufacturing facility delivers consistent basalt products. With robust production capabilities, we ensure high quality, reliable delivery schedules, and tailored sizing options for global infrastructure projects.

Every basalt steel bar from China Beihai undergoes testing to meet strict international standards
For global engineering and design authorities to specify **China Basalt steel bar strength** in critical infrastructures, materials must fully conform to established design standards. All BFRP rebars fabricated by China Beihai conform strictly to the **ASTM D7957** standard specification for solid round glass and basalt fiber reinforced polymer bars for concrete reinforcement.
In addition, our materials align with the structural design recommendations of **ACI 440.1R** (Guide for the Design and Construction of Structural Concrete Reinforced with FRP Bars). We conduct rigorous testing for fiber volume fraction (aiming for >70% fiber content), transverse shear strength, and long-term durability in alkaline environments.
By working directly with China Beihai, sourcing managers can request certified testing sheets for every batch of rebars, including detailed tensile modulus curves and thermal expansion coefficients.
Our factory practices rigorous quality control, managing every phase from selecting the basalt rock blocks to the pultrusion line. This ensures we deliver dependable BFRP basalt steel bars to our partners worldwide.

Expert engineering answers about basalt steel bar strength, design configurations, and bulk procurement logistics
Basalt Fiber Reinforced Polymer (BFRP) rebars offer a high tensile strength exceeding 1200 MPa, which is roughly three times that of structural Grade 60 carbon steel. While their tensile capacity is superior, their modulus of elasticity ranges from 45 GPa to 55 GPa. As a result, structural engineers typically design BFRP reinforced concrete members using serviceability limit states (deflection and crack width controls) in accordance with ACI 440.1R guidelines.
Because BFRP is a thermoset composite material, it cannot be bent on-site after the manufacturing resin has fully cured. All structural bends, such as stirrups and corner wraps, must be specified during the design phase. China Beihai manufactures pre-bent basalt configurations at our facility in Jiujiang according to client drawings.
Our typical lead time for custom batch runs is 15 to 25 days, depending on the required rebar diameters and volume. China Beihai runs continuous automated production lines, enabling us to handle large-scale global infrastructure orders. We coordinate with shipping hubs to manage container transport effectively.
Untreated basalt fibers can degrade in highly alkaline environments. To prevent this, China Beihai coats our basalt fibers with a protective vinyl ester or epoxy resin matrix. This matrix acts as an effective chemical barrier, allowing the rebar to maintain its strength over long-term exposure.
