Airport fences are core protective facilities for ensuring the safety of airport airspace and ground, mainly deployed around key areas such as runways, aprons, terminals, and oil storage areas.

Its design integrates anti-climbing, anti-vandalism and warning functions. Common materials include high-strength galvanized steel wire, aluminum alloy or stainless steel, and the surface is treated for anti-corrosion, making it suitable for complex environments such as open-air and high-humidity airports. Structurally, Y-shaped barbed wire, blade barbed wire or close-mesh welded wire mesh is mostly adopted. The mesh is fine and the columns are reinforced. Some are equipped with intelligent monitoring devices such as infrared alarms and vibration sensors.

In addition to physical isolation, fences are usually equipped with prominent warning signs and reflective strips, serving the functions of preventing illegal intrusion, animal intrusion, and guiding the flow of people and vehicles. They are important infrastructure for maintaining the safety of flight take-offs and landings and preventing potential safety hazards, and must comply with relevant safety standards of the Civil Aviation Administration as well as technical requirements such as impact resistance and shear resistance.
