The ALUMINUM WINDOW NET 4″ is a protective mesh screen used in window systems to enhance ventilation while preventing the entry of insects, dust, and small debris. Manufactured from lightweight yet durable aluminum material, it offers excellent corrosion resistance and long service life, making it suitable for both indoor and outdoor applications. The 4-inch specification typically refers to the profile or frame width used in window installations, providing compatibility with standard window framing systems. The aluminum mesh structure ensures consistent airflow while maintaining a protective barrier against mosquitoes, flies, and other airborne particles. This window net is widely used in residential buildings, commercial properties, offices, and industrial facilities where hygiene, airflow, and environmental protection are required. It is suitable for installation in aluminum, uPVC, or fabricated window frames depending on system design.   The product offers a balance of strength and visibility, ensuring clear outward view while maintaining protection. Specifications such as mesh density, frame thickness, and coating may vary depending on manufacturer standards.
