As a leading manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory specializes in producing high-performance Engineering Material Alkaline Resistant Fiberglass Mesh with a remarkable 90% alkali retention rate for exterior wall applications. Our fiberglass mesh is engineered to withstand the harsh alkaline environment of cement-based construction materials, ensuring long-term durability and structural integrity. With over two decades of experience and annual exports reaching US$5 million to US$10 million, we deliver reliable solutions that meet the rigorous demands of global construction projects.
Our product is designed to provide superior reinforcement for exterior wall insulation systems, preventing cracks and extending the service life of building facades. The mesh is treated with a special alkali-resistant coating that maintains its strength even when embedded in cement mortar. This ensures that your exterior walls remain stable and crack-free under varying weather conditions.
Key Features & Benefits
- High Alkali Resistance: ≥90% alkali retention rate ensures the mesh retains its tensile strength in alkaline environments, making it ideal for cement-based systems.
- Excellent Tensile Strength: With a minimum tensile strength of 1200 N/50mm, our mesh provides robust reinforcement for exterior walls.
- Lightweight yet Durable: The fiberglass material offers a high strength-to-weight ratio, reducing load on the structure while maintaining performance.
- Good Flexibility: Easy to cut and install, conforming to various wall shapes and contours.
- Customizable Specifications: Available in multiple mesh sizes, weights, colors, and roll dimensions to match your project requirements.
- Corrosion & Weather Resistance: The alkali-resistant coating also protects against moisture, UV rays, and temperature fluctuations.
- Eco-Friendly: Made from non-toxic, inorganic fiberglass material, safe for both installers and the environment.

Why Choose Our Fiberglass Mesh?
Our Engineering Material Alkaline Resistant Fiberglass Mesh is the result of continuous research and development, combined with advanced manufacturing techniques. The high alkali retention rate of 90% ensures that the mesh maintains its structural performance even after long-term exposure to cement paste. This is critical for exterior wall insulation systems (ETICS) where the mesh is embedded in the base coat and must resist alkali attack from the cement.
The mesh is woven from high-quality fiberglass yarns and then coated with a specially formulated alkali-resistant polymer. This coating not only protects the glass fibers but also improves the bonding with mortar. The result is a product that offers excellent crack resistance, impact resistance, and dimensional stability.
Our factory uses strict quality control measures at every stage of production, from raw material inspection to final packing. We can provide test reports upon request to verify the alkali retention rate and tensile strength. This transparency gives our customers confidence in the product's performance.
Applications
- Exterior Wall Insulation Systems (ETICS/EIFS): Used as reinforcement layer to prevent cracks and improve impact resistance.
- Interior Wall Plastering: Reinforces plaster layers to minimize shrinkage cracks.
- Concrete Structures: Strengthens concrete surfaces, columns, and beams.
- Tile Backing: Provides a stable base for tile installation on walls and floors.
- Waterproofing Systems: Enhances the durability of waterproof membranes.
- Marble/Stone Reinforcement: Prevents cracking in thin stone veneer applications.

Frequently Asked Questions
-
What makes your fiberglass mesh alkali-resistant?
Our mesh is coated with a special polymer that creates a barrier against alkaline substances. The coating is applied after weaving, ensuring the glass fibers are protected from cement's high pH. The alkali retention rate is tested to be ≥90%. -
Is the mesh suitable for all exterior wall systems?
Yes, it is designed for use with various exterior insulation and finish systems (EIFS/ETICS). It can be embedded in cement-based or polymer-modified base coats. -
Can you provide custom mesh sizes and weights?
Absolutely. We offer customization for mesh size (e.g., 4×4mm, 5×5mm, 10×10mm), weight per square meter (from 110g to 200g), width, length, and color. Minimum order quantity may apply for custom specifications. -
How do you ensure the 90% alkali retention rate?
We conduct regular testing using standard methods such as immersion in alkaline solution (e.g., 5% NaOH at 60°C for a specified time) and then measure the tensile strength retention. Test reports are available upon request. -
What is the typical shelf life of the mesh?
When stored in a cool, dry place away from direct sunlight, the mesh can be preserved for at least 2 years without significant degradation of the alkali-resistant coating. -
Do you offer samples for testing?
Yes, we provide free samples for evaluation. Customers only need to cover the shipping cost. We can also send a sample roll of 1m² for testing. -
How is the product packed for export?
Each roll is wrapped with a plastic film inside and a woven bag outside. Rolls are then packed into pallets or as per customer requirements. The packaging ensures protection during long-distance shipping. -
What is your lead time for bulk orders?
For standard specifications, the lead time is typically 7-15 days after order confirmation. For customized products, it may take 15-25 days, depending on the quantity and complexity.
