Extremely high security level,combining robust structure,anti-climb design,and top deterrents.Superior corrosion resistance for harsh airport environments.High overall stability with deep foundations resists strong winds.Relatively transparent for security patrol observation.Topped with razor wire or barbed tape for a formidable barrier.Designed to international standards(e.g.,ICAO).
Height typically≥2.5m(often higher).Mesh diameter≤50mm(prevents human passage).Wire diameter≥5.0mm.Mesh attached to Y-posts with high-strength alloy bands(hard to remove).Posts:≥60mm round tube or≥75x75mm SHS,wall thickness≥3.0mm.Strict requirements for foundation depth and concrete grade.
Specifically for civil/military airfield OFA perimeter security,strictly separating it from public areas to prevent unauthorized intrusion by people,animals,or vehicles,ensuring aircraft operational safety.Also used for other high-security sites:nuclear facilities,strategic reserves.
