As a leading manufacturer with over 25 years of experience, Anping County Boli Hardware Wiremesh Products Factory proudly presents our 316 Stainless Steel Insect Screen – a premium solution designed for demanding environments. Engineered with a 20x20 mesh count and 0.3mm wire diameter, this coastal grade screen offers exceptional corrosion resistance, making it ideal for windows, doors, and ventilation systems in coastal or industrial areas. Our robust manufacturing capabilities and annual export value of US$5-10 million ensure consistent quality and global supply.
This insect screen combines superior durability with fine visibility and effective insect protection. The 316 stainless steel alloy provides excellent resistance against salt spray, humidity, and chemical exposure, while the 20x20 mesh (20 openings per inch in both directions) effectively blocks mosquitoes, flies, and other small insects without compromising airflow or light transmission.

Frequently Asked Questions (FAQ)
1. Can this screen be used in saltwater environments?
Yes, our 316 stainless steel insect screen is specifically designed for coastal and marine environments. The higher molybdenum content (2-3%) provides excellent resistance to chloride-induced corrosion, making it suitable for beachfront homes, boats, and offshore platforms.
2. How does 20x20 mesh compare to standard 18x16 or 16x18 screens?
The 20x20 mesh has more openings per inch, offering finer insect protection (blocks smaller insects like no-see-ums and gnats) while still providing good airflow and visibility. It is slightly denser than standard screens, but for most residential applications, the difference in light transmission is minimal.
3. Is the 0.3mm wire strong enough to withstand pets or impacts?
Yes, 0.3mm wire is a common thickness for insect screens. It is strong enough to resist tearing from normal use, but we recommend using a heavier gauge (e.g., 0.4mm) if you have large dogs or frequent high impact. The 316 stainless steel provides additional strength and flexibility.
4. Can I order custom sizes? What are the minimum order quantities?
Absolutely. We offer custom widths and lengths to meet your specific requirements. For standard rolls, the minimum order quantity is one roll (30m). For custom sizes, please contact us with your dimensions – we can accommodate small quantities for sample orders as well.
5. How do I clean and maintain this screen?
Cleaning is simple: use a soft brush or vacuum with a brush attachment to remove dust and debris. For stubborn dirt, rinse with fresh water and mild soap. Do not use abrasive cleaners or steel wool, as they may scratch the surface.
6. Does the screen require any special frame or installation tool?
No special tools are required. The screen can be installed in standard screen frames using a spline and roller. It is flexible enough to cut with scissors or a utility knife. We recommend using a 316 stainless steel frame for coastal areas to match corrosion resistance.
7. What is the difference between 304 and 316 stainless steel for insect screens?
316 stainless steel contains 2-3% molybdenum, which significantly improves its resistance to chlorides (salt, bleach, seawater) compared to 304. For coastal or industrial environments, 316 is the preferred choice for long-term durability. 304 is suitable for inland areas with less corrosive exposure.
8. Do you provide samples before bulk order?
Yes, we offer free samples (A4 size or 1 square foot) upon request. You can test the mesh, visibility, and corrosion resistance in your specific environment. Shipping costs for samples may apply, but we will deduct the sample cost from your first bulk order.
