High-Security Fences: How to Understand Fence Ratings

When you’re browsing through our high-security fences, you might’ve noticed a symbol that says K4, K8, or K12.


At Hercules High Security, our fence ratings are formulated to help commercial and government agencies understand the strength within each high-security fence installation. When you’re browsing through our high-security fencing installations, you might’ve noticed a symbol that says K4, K8, or K12. These are all guidelines used by facility security to establish varying levels of protection in high-security applications. Hercules High Security can help you navigate what each level means and how they can protect your facility. 

High-Security Fences: K4-Rated Fencing

K4-rated fencing can prevent a vehicle weighing up to 15,000 pounds from passing through the fence at approximately 30 mph. As one of the most secure fence installations from vehicles attempting to gain unpermitted entry, you can rely on K4-rated fencing for commercial, government, and special facility installations. All of our K4-rated fences have been tested by an independent crash facility to ensure they adhere to state standards. 

K8-Rated Fences

K8-rated fencing is a step up from K4-rated fencing. K8-rated fencing can completely stop 15,000 pound vehicles from crashing into your fences perimeter traveling up to 40 miles per hour. Since all of our fences are tested at an independent crash facility to ensure that they meet state regulations, you can rely on Hercules High Security for all of your high-security anti-crash fencing needs. Think of K8-rated fencing being the middle level of security between K4-fencing and K12-fencing

K12-Rated Fences

K12-rated fencing is the most secure crash-rated fencing on the market that is available for commercial, government, and special facility installations. K12 fencing can withstand a 15,000 pound vehicle attempting to gain entry at up to 50 miles per hour and prevent it from gaining unpermitted access into your property. Since K12-rated is considered the strongest amongst K4 and K8 fencing options, you can feel secure in your high-security fence application.
