"Security in Every Job" Since 1955

A Guide to K-Ratings

k-rated-fenceWhen the security of your home or commercial property ranks highest on your list of priorities, you’ll want the best product on the market. Security fences come in numerous sizes, shapes, colors, and materials, and it can be difficult to assess the safety level of each option. Thankfully, in the early 2000s, a system was developed to help you navigate your choices with greater accuracy. K-Ratings provide a standard for security that will allow you to make informed decisions.

How are K-Ratings determined?

This system for rating the security level of fences was designed and executed by the United States Department of Defense. There are three different grades of k-rating, and each one is determined based on the same test. In order to achieve any k-rating the bed of the vehicle must not penetrate the barrier by any more than one meter or 36 inches.

K-4 rated fences are able to withstand the force of a 15,000-pound vehicle hitting it at 30 miles per hour.

K-8 rated fences are able to withstand the force of a 15,000-pound vehicle hitting it at 40 miles per hour.

K-12 rated fences are able to withstand the force of a 15,000-pound vehicle hitting it at 50 miles per hour.

Notes on testing

-The average vehicle ways somewhere around 3,000 to 4,000 pounds, meaning that the trucks used in the tests are about five times heavier than the car you drive around.

-You might think that if a vehicle is allowed to penetrate the barrier by 36 inches, the barrier is clearly not doing its job. In fact, if the truck breaches the barrier at all, its cab and anyone in it will undoubtedly be completely crushed to oblivion.

What purpose do k-rated fences serve?

K-rated fences are the highest performing security fences and are often used to protect federal and state government buildings as well as military compounds as anti-terrorism barriers. You’ll likely come across several k-rated fences on your average walk around Washington D.C. Some high-profile private residences also employ k-rated fences for protection.
