Facility types and what each one is protecting
Public facilities do not share a single fence specification. A courthouse is managing vehicle standoff and public access, a water treatment plant is managing contamination risk and unattended hours, an airport is managing controlled-area breach, and a corrections facility is managing containment — four different systems that happen to use the same materials.
| Facility | Primary driver | Typical system |
|---|---|---|
| Federal buildings and courthouses | Vehicle standoff, controlled pedestrian approach, public appearance | Crash-rated bollards and barriers at the approach, ornamental fencing at frontage, rated gates at service entries |
| Water and wastewater treatment | Contamination risk and long unattended hours | 8 ft chain link with barbed or razor topping, anti-climb mesh at clearwells, tanks and chemical storage |
| Airports and airfields | Controlled-area integrity and wildlife exclusion | Chain link with topping, buried or skirted fabric, vehicle gates with position monitoring |
| Corrections and detention | Containment rather than intrusion | Engineered systems with inward-facing detailing, razor coil, sally-port gates, detection-ready fabric |
| Military and National Guard | AT/FP standoff, controlled access, force protection | Anti-climb fabric, ASTM F2656 barriers at ACPs, hardened gate assemblies |
| Parks, public works and municipal yards | Equipment and material security, public separation | Chain link yard fence, ornamental at public frontage, slide gates with keypad or fob access |
| Schools and campuses | Layered campus security and life safety | See school, campus and institutional fencing |
