Explore our foundational range of high-performance continuous basalt fiber products, manufactured to withstand extreme temperatures, mechanical stress, and aggressive chemical environments.
Unlocking the Thermodynamic Superiority and High-Performance Mechanical Applications of Continuous Basalt Composites
Historically recognized for its incredible compressive strength in volcanic geological formations, columnar basalt represents one of nature's most robust structural wonders. The uniform, slow-cooling crystallization process of basic lava creates hexagonal, pentagonal, and octagonal columns of incredible density. In modern structural engineering, we have unlocked a massive information gain by taking this raw, thermodynamic resilience and turning it into Continuous Basalt Fiber (CBF) and custom-fabricated structures.
Unlike traditional E-glass or carbon fiber composites, basalt fiber is a 100% natural, green material, synthesized by melting selected volcanic rock components at ultra-high temperatures (1450°C to 1500°C) with no added chemicals. This single-component material offers structural designers an unparalleled combination of corrosion resistance, fireproofing capabilities, and extreme thermal limits, while maintaining an eco-friendly carbon footprint.
At China Beihai Group, we refine raw basalt into precision engineered composites—such as basalt fiber mats, rovings, chopped strands, twisted yarns, and custom concrete rebars. This deep scientific specialization provides the exact performance profile required in modern deep foundation engineering, municipal highway design, aerospace structures, and high-temperature industrial pipelines.

A detailed inspection of two core industrial solutions: continuous multi-filament roving packages and high-performance composite concrete reinforcement bars.
Our basalt fiber roving is a collection of continuous untwisted parallel strands or single-end strands processed directly from pure volcanic stone melt. It serves as the vital base material for winding pipes, storage tanks, pultrusion profiles, and weaving structural fabrics.
Coated with customized sizing agents (silane-based), our rovings are designed to achieve complete compatibility with epoxy, vinyl ester, polyester, and phenolic resin systems. This ensures extremely fast wetting, clean processing with minimal fuzz generation, and high interlaminar shear strength in completed composites.
As an advanced rust-proof and lightweight alternative to traditional steel bars, basalt rebar exhibits superior acid and alkali resistance. This makes it an invaluable asset in concrete construction exposed to marine spray, deicing salts, or chemical processing plants.
Designed for heavy civil engineering, bridge deck panels, and municipal highways, our basalt composite rebar possesses a density of only 1/4 that of traditional steel, yet offers over 2 times the ultimate tensile capacity. It drastically reduces structural dead-load while extending service lifetimes to over 100 years.

Continuous Basalt Fiber (CBF) occupies a high-value mid-tier performance and cost segment between E-glass and carbon fibers. CBF offers a 30% higher tensile strength, significantly higher elasticity modulus, and far superior acid, alkali, and chemical resistance than standard E-glass.
When compared to carbon fiber, basalt fiber is much more cost-effective, provides natural RF (radio frequency) transparency, and can function across wider thermal bounds (stable from cryogenic ranges up to 700°C), making it the premier option for complex architectural and electrical applications.
Steel rebar rusts when moisture, salt, and oxygen penetrate concrete, causing internal cracking and structural failure. Basalt rebar is inherently chemically inert and 100% rustproof. It maintains complete structural integrity when exposed to extreme marine conditions, tidal splash zones, and aggressive alkaline soil components.
Furthermore, because basalt composite rebar has a thermal expansion coefficient highly similar to high-density concrete, it eliminates internal shear stress under massive temperature fluctuations.
At China Beihai, we run advanced high-speed filament winding lines with specialized chemical sizings. Sizings act as the crucial coupling agent interface between the basalt filament surface and the matrix resin.
We manufacture customized silane-based sizing configurations designed for quick compatibility with Epoxy (EP), Vinyl Ester (VE), and Unsaturated Polyester (UP) resins, along with specialized thermal sizings for high-temperature injection molding (BMC/SMC processes). This maximizes interlaminar shear strength (ILSS) and prevents air pocket formation.
Our entire supply system undergoes rigid testing procedures. All batches are checked for moisture levels (held below 0.2%), resin-compatibility indexes, and single-filament tensile limits.
We operate strictly under ISO 9001 quality management guidelines, and all continuous fiber and composite rebar series carry accredited CE certificates, assuring international structural conformity.
