Apply general anti-climb/security fence design and testing standards for critical-infrastructure perimeter fencing.

Steps

1. Confirm the project's forced-entry/anti-climb performance requirement by referencing ASTM F2781 (the primary third-party testing/classification framework for forced-entry resistance in commercial/civilian security fencing) rather than an unverified proprietary "military-grade" marketing claim.
2. Apply general anti-climb design principles: minimal handholds/footholds, small mesh aperture sized to resist toe/finger insertion, rounded or angled toppings, and sufficient height combined with a rotating or outward-canted top section.
3. Check whether the specific critical-infrastructure sector (utility substation, water treatment, airport) has its own sector-specific perimeter security mandate layered on top of general fencing standards (e.g., NERC CIP physical security requirements for bulk electric substations).
4. Verify manufacturer forced-entry/anti-climb performance claims against actual independent test reports rather than marketing literature alone.
5. Coordinate with the facility's security consultant or the sector regulator on detection/deterrence layering (fencing plus intrusion detection, lighting, cameras), since fencing alone is rarely the sole compliance measure for regulated critical infrastructure.
