At Anping County Boli Hardware Wiremesh Products Factory, we take pride in delivering premium quality 304 Stainless Steel Fly Screen Mesh that meets the rigorous demands of modern pest control and ventilation. Our 20x20 mesh standard compliant product is engineered to provide effective insect exclusion while maintaining excellent airflow and visibility. Backed by our Mill Test Report, each roll guarantees material traceability and consistent performance, making it a reliable choice for residential, commercial, and agricultural applications.
Since our establishment in 1998, we have focused on manufacturing wire mesh solutions that combine durability, precision, and value. Our fly screen mesh is produced from high-grade 304 stainless steel wire, offering exceptional corrosion resistance and long service life even in humid or coastal environments. The 20x20 mesh density (20 openings per inch in both directions) strikes an ideal balance between keeping out tiny insects like mosquitoes, flies, and gnats, and allowing ample light and air circulation.
Every batch undergoes strict quality control, and we provide a Mill Test Report upon request to verify the material composition and mechanical properties. This commitment to transparency and quality assurance has enabled us to serve clients across North America, South America, Europe, Africa, Oceania, and Asia with annual export values ranging from US$5 million to US$10 million.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between 304 and 316 stainless steel for fly screen mesh?
A: 304 stainless steel offers excellent corrosion resistance for most environments. 316 provides higher resistance to chlorides and harsher conditions, but is more expensive. For standard residential and commercial insect screens, 304 is a cost-effective and durable choice. -
Q: Can I get a sample before placing a bulk order?
A: Yes, we provide free samples (just cover shipping cost) for you to evaluate the mesh quality, finish, and weave. Contact us with your address and requirements. -
Q: How is the Mill Test Report provided?
A: The Mill Test Report is issued by our steel supplier and can be included with your shipment. We can also send a scanned copy via email prior to dispatch. It confirms the material grade, tensile strength, and chemical composition. -
Q: Is the 20x20 mesh effective against small insects like gnats or no-see-ums?
A: 20x20 mesh has openings approximately 1.0–1.2 mm, which blocks most flying insects (mosquitoes, flies, gnats). For very tiny insects like midges, you may consider 30x30 mesh. We can supply both options. -
Q: What is the typical lead time for orders?
A: Standard production takes 10–15 working days after order confirmation. For rush orders, we can expedite based on stock availability. Shipping time depends on destination. -
Q: Do you offer PVC or epoxy coated mesh for added durability?
A: Yes, we offer optional PVC or epoxy coating. Coated mesh is more resistant to scratches and UV fading, and comes in colors like black, white, or gray. Please specify your preference. -
Q: Can the mesh be used for pet doors or large openings?
A: Absolutely. The mesh is flexible but strong; it can be installed in fixed frames, sliding doors, or retractable screens. For large areas, we recommend using a heavier wire diameter (e.g., 0.25 mm) for better tension. -
Q: What is the minimum order quantity (MOQ)?
A: MOQ is 100 square meters for standard sizes. Custom sizes may have a higher MOQ. We also accept small trial orders for first-time buyers.
