Engineered to withstand extreme chemical stress, our composite solutions provide superior tensile strength and durability for global infrastructure projects.
Why standard reinforcement meshes fail in concrete environments—and how our advanced chemical engineering prevents degradation.
Portland cement concrete is highly alkaline, typically maintaining a pH between 12.5 and 13.5. Standard glass fibers (like E-glass) rapidly degrade in this environment due to silica dissolution. Our custom alkali-resistant (AR) mesh uses high-purity basalt and specialized zirconia-doped glass fibers to resist alkaline attack, ensuring structural integrity over decades.
To achieve true chemical inertness, our AR glass fibers are formulated with a minimum of 16.7% Zirconia ($ZrO_2$). Zirconia forms a passive barrier on the fiber surface, blocking hydroxyl ions ($OH^-$) from breaking the silicon-oxygen bonds. This molecular-level protection is what distinguishes premium industrial mesh from cheap retail alternatives.
Beyond the core fiber chemistry, our mesh is treated with a proprietary Styrene-Butadiene Rubber (SBR) or acrylic copolymer emulsion. This coating serves a dual purpose: it acts as a secondary physical barrier against moisture and alkaline ions, and it provides the mechanical lock required to transfer stresses efficiently across the concrete matrix.
How modern engineering standards and sustainability mandates are shaping the global supply chain for structural composites.
Basalt fiber is ideal for your engineering projects. Its high strength, corrosion resistance and lightweight properties allow it to easily solve a variety of challenges. In buildings, bridges, roads and other infrastructure projects, basalt fibers demonstrate outstanding performance, extending structural life and reducing maintenance costs. Choose basalt fiber, choose reliability and durability.
Globally, procurement directors are shifting away from traditional steel reinforcement in thin-walled concrete and exterior cladding systems. Steel is heavy, prone to rust, and requires significant concrete cover. Our custom basalt AR mesh offers a zero-corrosion alternative that allows for thinner, lighter, and more architecturally complex concrete designs while drastically lowering the carbon footprint of the project.

Read the Full WhitepaperExpert answers to the most common technical questions regarding alkali-resistant mesh and basalt fiber reinforcement.
Concrete is highly alkaline (pH 12.5–13.5). Standard glass fibers undergo a chemical reaction called silica dissolution when exposed to hydroxyl ions, which destroys their tensile strength. Alkali-resistant mesh is chemically engineered—either through high Zirconia ($ZrO_2$) content or chemically inert basalt fibers—to withstand this harsh environment, ensuring long-term structural reinforcement.
Basalt AR mesh is made from continuous basalt filaments extruded from melted volcanic rock, which is naturally resistant to alkalis, acids, and extreme temperatures. AR Glass mesh is a manufactured silicate glass that requires the addition of Zirconia ($ZrO_2 \ge 16.7\%$) to achieve similar chemical resistance. Basalt generally offers higher tensile strength and a wider operating temperature range.
The Styrene-Butadiene Rubber (SBR) coating acts as a physical shield protecting the fibers from direct contact with alkaline concrete paste. Additionally, it provides dimensional stability to the woven grid, preventing shifting during installation, and significantly improves the mechanical bond (interlocking) between the mesh and the mortar.
As a direct manufacturer, we offer extensive customization. We can adjust the grid size (e.g., 4x4mm, 5x5mm, 10x10mm), roll width (up to 2.2 meters), roll length, coating type (soft or stiff finish), and weight per square meter (from 45g/m² to 600g/m²). We can also print custom logos directly on the mesh or packaging.
Our manufacturing processes are certified under ISO 9001:2015. Our alkali-resistant meshes are tested in accordance with international standards, including ASTM C1666 (for alkali resistance testing), ETAG 004 (for EIFS/ETICS systems), and CE marking requirements for the European construction market.
