What You Need To Know About K-Ratings

K-Rated barriers are typically used for commercial and government buildings, but can sometimes be used for high profile residences as well.

K-Rated barriers are typically used for commercial and government buildings, but can sometimes be used for high profile residences as well.

To put it shortly, K-ratings are crash test certifications used for fences, gates, or bollards before they are installed. It essentially measures how much power the barrier has if a vehicle were to ever crash into it. They base these K-ratings off of the weight and speed of a vehicle. Here is what you need to know about K-ratings.

The 3 Classifications

There is a standard weight for all K-ratings which is 15,000 pounds. In order for the barrier to be certified by the Department of State, the truck shouldn’t go any further than 36 inches past where the barrier is when it collides with it. There are three classifications of K-ratings:


  • K4: A vehicle traveling 30 mph
  • K8: A vehicle traveling 40 mph
  • K12: A vehicle traveling 50 mph


When Does Your Fence Need A K-Rating?

If you are just looking for a fence to surround your home, you don’t necessarily need a crash tested fence. Crash rated products are geared more towards commercial and government establishments. They can, however, be used for very high profile residences. Establishments that can potentially be harmful if crashed into (i.e power plants, chemical plants) have crash rated barriers installed around them. K-ratings are now the standard for anti-terrorism crash protection as well, which is needed for high profile government buildings.

What Gives Barriers A K-Rating?

In order to achieve a K-rating, extra materials must be added to barriers to make them sturdier. Perimeter fences and gates are given cable or beam reinforcements to give them more strength. Barriers such as bollards and wedge barriers use enhanced materials and a stronger foundation such as heavier steel gauges.
