Fence Height: The height of football field fences is generally 2-4 meters, with mesh openings ≤75mm, while tennis courts recommend a height of 3-4 meters and mesh openings ≤50mm. Fence Material: Fence frames are primarily made of materials such as low-carbon steel, stainless steel, and aluminum alloy, offering anti-aging and corrosion-resistant properties. Anti-Climbing Design: Horizontal support bars or barbed tape can be added to enhance security. Special Requirements: For children's playgrounds, materials without sharp edges should be selected, and the installation height should be reduced (1.8-2.5 meters).
