Common Questions About Road Blockers and Their Expert Answers!

11. How is Road Blocker Reliability Measured?

Its reliability is measured through cycle testing, crash-test certifications, material durability, and performance under extreme weather. Manufacturers usually test the system through thousands of opening and closing cycles to ensure long-term dependability. Reliability is also evaluated by failure rate, response time, and the ability to operate during power loss with backup systems.

12. What Are the Crash Ratings of Crash Barriers?

They are commonly rated according to global crash standards, such as K-Rating (K4, K8, K12) and PAS 68/IWA 14-1.

These ratings show the blocker’s ability to stop a vehicle of a certain weight coming at a specific speed. For example, a K12 rating means the blocker can stop a 6,800 kg truck travelling at 80 km/h. Higher ratings indicate stronger impact resistance.

13. How Much Load Can a Security Barrier Resist?

A typical heavy-duty barrier can resist impact forces from several tonnes and high-speed vehicles. Depending on the crash rating, a Pop-Up Barrier may withstand impact from vehicles weighing 6,800 kg to 7,500 kg at speeds of 50 to 80 km/h. Some military-grade models can handle even greater forces.

14. What Are the Different Types?

Road blockers come in several types depending on their protection level and installation area, including:

• Shallow-Mount 
• Deep-Mount 
• Surface-Mount
• Wedge
• Delta – D Type

Each type is chosen based on threat level, available space, operation type(manual or automatic) and budget for road blockers.

15. Can Road Barrier Protect a Building Against Terror Attacks?

Yes. Crash-rated kerbs are specifically designed to protect people, property, and critical infrastructure from terrorist vehicle attacks. They can stop high-speed trucks, car bombs, and forced vehicle entries. Facilities such as embassies, airports, military bases, and government buildings rely on them because they provide strong perimeter defence.

16. Are they Eco-Friendly?

Modern barriers are more eco-friendly than older models. They use energy-efficient hydraulic or electromechanical systems and require minimal power during operation. Many models also use recyclable steel and low-maintenance components, reducing their environmental impact.

17. What’s the Difference Between a K-Rated Barrier and an Ordinary Barrier?

A K-rated barrier has been tested and certified to stop a heavy vehicle moving at high speed. It provides guaranteed protection in accordance with international crash-test standards.

An ordinary roadblocker does not provide certified stopping power and cannot reliably prevent a high-speed vehicle attack. K-rated road blockers are used for high-security zones, while ordinary road blockers are suitable for basic traffic control.

18. Which Type of Crash Barrier Is Best for My Facility?

The best type depends on your security level, available installation depth, traffic volume, and budget.

• High-threat areas: Crash-rated or K-rated blockers
• Sites with limited excavation depth: Shallow-mount blockers
• Commercial buildings: Hydraulic rising blockers
• A security expert should inspect your site to recommend the right system.
