High Security Steel Palisade Fence

Maintaining a secure perimeter is your first line of defense against potential threats. An Impasse II fence serves as a visual deterrent backed with heavy steel components that give a higher level of protection compared to the traditional chain link or architectural mesh fence alternatives. Impasse II is the best choice for securing at risk facilities or protecting specific assets within a property.

Anti-Scale Option: Deter & Delay

The Impasse II Anti-Scale fence system option decreases the pale spacing to deter the assailant from climbing and increase the delay time when trying to cut or pry through the fence. To further increase delay time from a possible perimeter breach, expanded metal fillers can be positioned between the pales and rails, allowing the facility more time to react.
