K-Rated Fences: What to Know Hercules GSA

Here is what you need to know about K-rated fences.

If you’re in the market for a high-security fence, you must know about K-ratings. After all, business security is not something you should take lightly. It is up to you to do all the necessary research to make sure you have the product that you need. The K-rating system may seem rather technical. Today, we will do our best to break it down into simple terms. Here is what you need to know about K-rated fences.

What Are K-Rated Fences?

The Department of State first devised the K-rating system in 1985. The last time the system was revised was in 2003. They devised the system as a way of categorizing fences and their resistance to vehicle collisions.

Depending on the nature of your business, vehicles crashing into your fence could pose a major security threat. The K-rating system makes it easy for you to tell how well your fence would withstand a perpendicular crash from your average vehicle traveling at a particular speed.

What Do the Individual Ratings Mean?

Any K-rated fence has some resistance to vehicular collisions. But some can withstand crashes from faster-moving vehicles than others.

Before we dive into what the specific ratings mean, let’s take some time to examine the criteria by which fences are rated. When testing a fence for its K-rating, they will use the example of an average truck with a weight of 15,000 pounds. For testing purposes, the vehicle will collide perpendicularly with the fence. To achieve the K-rating, the vehicle should not penetrate 3 feet past the bed.

There are three different categories of K-rated fences. We can break them down by the speed of the vehicle:

  • K4: 30 mph

  • K8: 40 mph

  • K12: 50 mph

A K4-rated fence will be able to withstand a crash from a 15,000-pound vehicle traveling at 30 mph, and so forth.

Who Needs K-Rated Fences?

Any business seriously looking to amplify its security should consider K-rated fences. As you might have guessed, they are ubiquitous around government buildings or other high-security settings, such as prisons, but business owners should also consider them.

When evaluating your business’ security, far too many people overlook the threat of vehicle crashes. No matter how high your fence is, or how well it has been fortified with barbed wire, there is no stopping a vehicle without a K-rating.

Individuals seeking the highest standard in security should look no further than K-rated fences. Whatever rating you desire, we’re here to help.
