The world is becoming an increasingly volatile place with acts of terrorism and civil unrest. Recent acts of violence have caused destruction to property and have ended in harm to civilians and government personnel alike. In recent years, bad actors have used vehicles to breach physical barriers and cause mass damage.
Thankfully, crash gate systems act as both a deterrent and first line of defense for property and life. Crash gate systems prevent vehicles from breaching into critical infrastructure or vulnerable areas by providing a robust barrier that can withstand the heaviest impacts. This guide will tell you everything you need to know about crash gates so you can choose the right protective measures.

Understanding Crash Gate Ratings
Crash gate systems are rated differently depending on the intended use and the organization that will be using them. The United States has some common standards for crash gates outlined in the definition of standards.
Definition of Standards
The ASTM F2656 is the current US standard for crash rating requirements. Often, the Department of Defense, Department of State, Interagency Security Committee, and the US General Administration have additional requirements for verifying the performance of a security barrier. Organizations in the UK and other areas of the world have different standards.
Third party testing agencies are used to analyze barriers’ performance to see how they will withstand a vehicle impact that includes different vehicle weights, sizes, velocities, and angles of approach.
Previously, both the DOD and DOS used a “K” designation that describes the vehicle impact speed that the gate is successfully rated for. The K-ratings used were K rating (K4 = 15,000 lbs at 30 mph; K8 = 15,000 lbs at 40 mph; and K12 = 15,000 lbs at 50 mph). Whereas the “L” rating designates how far the vehicle’s cargo will penetrate beyond the barrier. The ASTM F2656 changed the “K” designation to an M-rating, M30 (K4), M40 (K8) and M50 (K12).
These penetration ratings are designed to create a standardized system that allows users to know precisely what their physical security measures can withstand. When purchasing a crash gate system for your organization, know exactly what these specifications and ratings are by requesting a copy of the test certification letter from the manufacturer directly.

Applications & Uses of Crash Barriers
The application of crash barriers can vary as many places need physical security measures to prevent and protect against breaches. The examples of properties below need to direct and control traffic while bolstering security.
Public Utilities – Crash gate systems are essential for public utilities. Water and power plants can benefit from these physical barriers because they contain vulnerable assets that could become a target.
Military & Police Installations – Bases, police headquarters, and other installations for military and police need the highest security measures as they have higher levels of threat from terrorism and warfare.
Borders – Borders need to direct the flow of traffic while preventing any attackers from breaching country lines.
Airports – Barriers can offer increased protection levels in these vulnerable areas that need the highest levels of security, such as hangers, terminals, and runways.

Types of Crash Barriers
Not all crash barriers are created equally. Crash barriers have different ratings as outlined below that can cater to other uses and levels of danger.
Crash gates and beams
These barriers have been designed by engineers to meet certain performance characteristics or industry specifications. With the aid of computerized programs, engineers can calculate how their design will withstand impacts.
These crash gate systems have been impact-tested and rated by a certifying 3rd party then are approved by the Department of Defense, State Department, or other agency. The testing agency tests to the desired crash rating of the manufacturer.
A reinforced crash gate will include extra security features that extend beyond the gate, such as cables, bollards, and other measures designed to stop vehicle ramming.
Crash Gate Systems
Below are some various gate types available in a crash gate system that offer different opening mechanisms and security features.
Vertical Lift Gate
Vertical lift gates will open and close vertically. These options are common in constricted spaces that do not allow for sliding gates. These crash gates are most often automated or controlled by an attendant.
Cantilever Slide Gate
This gate type will slide open horizontally to allow traffic through and provides a sturdy barrier when closed. They do not require any tracks or supports besides two posts on either side of the entryway. These gates are commonly seen as the entrance to compounds, embassies, and other secure areas.
Overhead Slide Gate
These gates have an overhead track but slide to the side of the opening. This type of gate allows very tall vehicles to enter and exit, so it is commonly seen in border crossings.
As their name suggests, these hinged gates swing open from a side of the entrance. Crash rated swing gates only open towards vehicles to provide a security stop against ramming. This will work well as long as there is ample room for vehicles in the driveway.
