Features

Superior intrusion resistance. The dual-panel design with interlocking spiral connectors makes the fence harder to breach and helps resist attacks from common hand tools, providing valuable delay time for security response.
Anti-climb mesh design. The front and rear panels use a narrow rectangular mesh structure that prevents finger and toe holds, effectively reducing climbing attempts.
Electronic security compatibility. The open mesh structure does not obstruct CCTV views or radar signals and can be integrated with vibration sensors, infrared beams, and other PIDS for enhanced perimeter protection.
Multi-stage corrosion protection. All steel components are treated with galvanized or zinc-aluminum alloy coatings and finished with powder coating for improved weather resistance and long service life. Coating requirements can be customized according to project needs.
- Front panel. Hot-dip galvanized or zinc-aluminum alloy coated (95% Zn / 5% Al), then powder coated
- Rear and connector panels. Hot-dip galvanized and powder coated
- Posts and fittings. Galvanized and powder coated
