Welcome to Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer since 1998 with an annual export value of US$5–10 million. We are proud to introduce our B1 Class Flame Retardant, UV Resistant, 30% Open Area Insect-Proof Solar Mesh Fabric, designed specifically for solar panel protection, greenhouse ventilation, and building insect screening. This innovative mesh combines multiple critical functions: it meets the strict B1 flame retardant standard, blocks over 90% of UV radiation, maintains a 30% open area for optimal airflow, and effectively prevents insect intrusion. Whether you are a solar farm developer, greenhouse operator, or building contractor, this fabric offers a reliable, long-lasting solution that enhances safety, energy efficiency, and pest control.

Key Features & Technical Specifications

B1 Flame Retardant Class: Tested according to DIN 4102 and GB/T 17591, our mesh self-extinguishes within 30 seconds, reducing fire risk in solar installations and building facades. Ideal for areas with strict fire codes.
Superior UV Resistance: With >3000 hours of QUV test performance, the fabric resists degradation from sunlight, maintaining its mechanical strength and color for years. This extends the lifespan of both the mesh and the underlying solar panels.
30% Open Area: Precision-woven to achieve a consistent 30% open area, allowing adequate air circulation while blocking insects. This balance prevents overheating of solar panels and reduces the need for chemical pest control in greenhouses.
Insect-Proof Design: Mesh count options (18×16, 20×20, 24×24 per inch) effectively block mosquitoes, flies, and other small insects without obstructing light transmission. The fabric is also resistant to corrosion and mildew.
High Tensile Strength: Made from high-tenacity polyester yarn (or fiberglass upon request), the mesh offers excellent tear and puncture resistance, suitable for long-term outdoor use.
Dimensional Stability: Low shrinkage (

Benefits to Your Business

Enhanced Safety: B1 flame retardancy reduces fire spread, protecting your assets and complying with building codes in many countries.
Lower Maintenance Costs: UV-resistant fabric prevents yellowing and brittleness, minimizing replacement frequency. The anti-insect feature also reduces cleaning and pest control expenses.
Improved Energy Efficiency: 30% open area allows natural ventilation, lowering cooling costs for greenhouses and solar panel systems. The mesh also reduces dust accumulation on panels.
Versatile Applications: Perfect for solar panel shading, greenhouse sidewalls, window screens, balcony enclosures, and agricultural insect nets. Custom sizes and colors match your specific project.
Eco-Friendly: Our fabric is free of heavy metals and recyclable, supporting sustainable construction and agriculture practices.

Frequently Asked Questions (FAQ)

Q: What does B1 flame retardant class mean?
A: B1 is a European standard (DIN 4102) indicating that the material is self-extinguishing and does not contribute to fire spread. Our fabric passes the B1 test and is also compliant with Chinese GB/T 17591. It is suitable for use in buildings and solar installations where fire safety is required.
Q: Can this mesh be used directly on solar panels?
A: Yes, it is specifically designed for solar panel protection. The 30% open area ensures minimal shading effect while preventing insect nesting and debris accumulation. The UV-resistant coating also protects the panels from long-term exposure.
Q: How long does the UV resistance last?
A: Based on QUV accelerated testing, the fabric maintains its mechanical properties and color for over 3000 hours of continuous UV exposure, which roughly corresponds to 5–7 years of outdoor use in moderate climates. Actual lifespan depends on local conditions.
Q: Is the 30% open area fixed or adjustable?
A: The 30% open area is a standard specification. However, we can customize the mesh count to achieve different open areas (e.g., 25% or 35%) based on your ventilation and insect protection requirements. Please contact us for details.
Q: What is the installation method?
A: The mesh can be cut to size and installed using standard fasteners, frames, or tension wires. It is flexible and easy to handle. We can provide installation guidelines upon request.
Q: Do you offer custom sizes and colors?
A: Yes, we offer custom width up to 3.0m and any length required. Standard colors are black, gray, and white. Other colors can be produced with a minimum order quantity (MOQ). Please inquire for details.
Q: Is the fabric resistant to chemicals or salt spray?
A: Our polyester-based mesh has good resistance to common chemicals and salt spray. For coastal or high-corrosion environments, we recommend our fiberglass variant which offers even better chemical resistance. Let us know your application environment.
Q: What is the minimum order quantity (MOQ)?
A: For standard sizes and colors, the MOQ is 1000 square meters. For custom specifications, MOQ may be higher. We also offer sample rolls for testing and evaluation.
