A security fence is a standard structure used by the RDA. They are constructed from reinforced steel lined with razor sharp wire, and some have an automatic weapons system to keep the Pandoran megafauna outside of RDA restricted areas. A very large fence was used in the Blue Lagoon, which had been damaged over time and patched with repulsor pods. There is also an extremely strong one around Hell's Gate, with defence turrets placed at each apex of the pentagonal shape.
They are not completely indestructible; for example the fence around Camp Anvil is heavily damaged and has been breached in multiple places. The RDA also makes use of electric fences to protect key areas.
