K4 Rated Bollards – Certification, Performance & Applications
When you need perimeter protection but the threat profile is moderate, our K4 Rated Bollards deliver a certified solution. These bollards are designed and tested to stop a 15,000-pound (≈ 6.8 t) vehicle travelling at around 30 mph (≈ 48 km/h) — providing reliable vehicle crash protection in commercial, corporate and infrastructure settings.
At Secure Bollard, we combine German-engineered design with Indian manufacturing excellence to supply K4 rated bollards that are fit for purpose, cost-effective, and performance-ready.
What Does “K4 Rated” Mean?
“K-ratings” are legacy crash-test ratings from the U.S. DoD/DoS used for bollards and barriers. A K4 rating indicates the bollard was tested to stop a 15,000-lb vehicle traveling at 30 mph. More recent standards like ASTM F2656 (e.g., M30) map to the same performance level.
This makes K4 rated bollards suitable for sites where high-security (e.g., K12) may not be required — but reliable barrier protection is still essential.

ASKED QUESTIONS
What is a K4 rated bollard?
A K4 rated bollard is a crash-tested security barrier capable of stopping a 15,000 lb (6.8-ton) vehicle traveling at 30 mph (48 km/h). It meets U.S. Department of Defense crash rating standards and is ideal for protecting areas that face moderate vehicle-impact risks.
What is the difference between K4, K8, and K12 rated bollards?
K4 Bollards: Stop a 15,000 lb vehicle at 30 mph
K8 Bollards: Stop a 15,000 lb vehicle at 40 mph
K12 Bollards: Stop a 15,000 lb vehicle at 50 mph
The higher the rating, the greater the crash resistance. K4 bollards are perfect for commercial, industrial, and corporate environments requiring medium-security vehicle protection.
What materials are used in Secure Bollard’s K4 rated models?
Secure Bollard’s K4 rated bollards are made from high-strength steel, with optional stainless steel or powder-coated finishes. Each bollard is corrosion-resistant and engineered for long-lasting durability even in outdoor environments.
Where can K4 rated bollards be installed?
These bollards are commonly used at:
Office building entrances
Parking lots and corporate campuses
Shopping malls and public areas
Data centers and logistics facilities
Government and transportation sites
They help prevent unauthorized vehicle entry and accidental collisions in restricted zones.
Are K4 rated bollards the same as ASTM M30 bollards?
Yes. Under the ASTM F2656 crash rating system, K4 corresponds to M30, meaning both are designed to stop a 15,000 lb vehicle at 30 mph. This ensures globally recognized safety standards.
What types of K4 bollards are available?
Secure Bollard offers:
Fixed K4 bollards – permanent installations
Removable K4 bollards – allow temporary vehicle access
Automatic or retractable K4 bollards – integrate with access control for high-traffic zones
How are K4 rated bollards installed?
Installation depends on site conditions — deep-mount and shallow-mount foundations are both available. Secure Bollard provides end-to-end installation support and ensures each system meets certified crash performance.
Can K4 bollards be customized?
Yes. You can choose custom finishes, colors, reflective bands, or architectural sleeves to match your site’s design aesthetics while maintaining full crash resistance.
Are K4 rated bollards suitable for high-security sites?
K4 rated bollards are ideal for medium-security applications. For critical infrastructures such as embassies or military bases, higher-rated models like K8 or K12 bollards are recommended.
