Anti-Terrorism (K-Rated) Bollards
A “K” rating is a Crash Test Certification issued by the Department of State (DOS) to a fence, gate, barrier or bollard indicating perpendicular impact penetration of a vehicle of a specific weight at a specific speed. In other words, it measures the particular stopping power of a barrier in relation to the speed and weight of an oncoming vehicle.
The K rating weight of the vehicle is standard at 15,000 lbs. These DOS standard barriers can only allow the truck to penetrate no more than 36 inches past the bed. “K” rated bollards are often referred to as Ram, Anti-Ram or Anti-Terrorism bollards.
