DS-22 Product Overview

The Delta Scientific DS-22 bollard is a Department of State-designed, K12/L3 crash-rated fixed bollard system engineered for permanent vehicle perimeter protection at high-security facilities. A K12/L3 rating means the system is designed to stop a 15,000 lb (6,800 kg) vehicle traveling at 50 mph (80 km/h), with the vehicle penetrating no more than 1 meter (3.3 ft) past the barrier, when installed as a 3-post array. In performance terms, it is comparable to an ASTM M50/P1 rated barrier.

Featuring three heavy-duty steel posts integrated into a reinforced concrete foundation, the DS-22 provides a robust physical barrier against vehicle threats while maintaining an open, accessible perimeter.

Designed for applications where dependable, long-term security is essential, the DS-22 is suited for a wide range of environments, including government facilities, embassies, courthouses, stadiums, dams, and critical infrastructure.

Backed by Delta Scientific’s more than 52 years of experience in vehicle barrier technology, the DS-22 offers a proven design for facilities where security cannot be compromised. Delta Scientific supplies the DS-22 with general arrangement drawings and technical specifications, and supports projects from specification through installation.
