Stalwart IS®Anti-Ram Barrier With High Security Steel Fence

Ameristar Stalwart Impasse IS High Security Fence with Anti-Ram Barrier


The Stalwart IS (Impasse Security) system integrates the strongest high security fence available with the most used anti-ram barrier. The Stalwart anti-crash barrier has been engineered and tested in compliance with current ASTM F2656-07 (Standard Test Method for Vehicle Crash Testing of Perimeter Barriers), and meets the demand for multiple vehicle threats.


Intimidating design elements of the Impasse palisade security fence portray strength and fortitude providing the best deterrent to intruders.


The Impasse framework provides a platform to incorporate various security peripherals required on high security perimeter designs. The components that define the Impasse fence framework are used to carry the anti-ram cable transforming the Impasse fence into the Stalwart IS crash fence system.
