Learn where crash-rated wedge barriers outperform gates and bollards for high-throughput lanes, constrained sites, and shallow foundation conditions. Includes Delta examples and EFO speeds.
Built for the Data Center Boom: The Fastest Crash Rated Bi-Fold Speed Gate in the World
For more than 50 years, Delta Scientific has engineered perimeter security systems for some of the most demanding environments in the world. Our barriers, bollards, gates, and access control systems protect government facilities, military installations, utilities, embassies, transportation hubs, and critical infrastructure sites globally.
Crash-Rated vs Non-Crash-Rated Bollards: What Facility Owners Need To Know
Learn the difference between crash-rated and non-crash-rated bollards, why many storefront posts are not tested, and how to choose the right level of vehicle stopping performance.
What SAFETY Act Certification Means for Perimeter Security
Learn what the The SAFETY Act, a program established by the U.S. Department of Homeland Security, means to the perimeter security industry. This program was created to encourage the development and deployment of proven anti-terrorism technologies.
Crowd Protection at City Events: Why Crash-Rated Portable Barriers Matter
Metal barricades manage crowds, not vehicles. Learn why city events now need crash-rated solutions and how Delta’s DSC50 S Barrier helps protect parades and festivals.
How to Write Performance-Based Specs for Vehicle Barriers and Bollards (Ratings, Penetration, Cycle Time)
A practical guide for engineers and architects on writing performance-based specs for vehicle barriers and bollards using crash ratings, penetration, duty cycle, and environmental requirements, without naming brands.
Why Improvised Barriers Fall Short in Protecting Crowds
Crash-rated barriers are designed, tested, and certified to perform under defined conditions. Learn how improvised barriers are never the best option.
UK Threat Level Raised to Severe: Why Preparedness Must Come First
The Threat Level Has Changed The UK has raised its national terrorism threat level from substantial to severe. This means an attack is highly likely. This is the official assessment from MI5. Source: https://www.mi5.gov.uk/uk-national-terrorism-threat-level-raised-to-severe Experience Shapes Response I have 20 years in the anti-terrorism vehicle barrier industry. Over that time, I have seen patterns repeat. […]
Portable Vehicle Barriers for Events: Protecting Streets Without Permanent Construction
Most event security plans have the same constraint: you need protection for a weekend, not a capital project. Portable vehicle barriers for events solve that by deploying on existing surfaces, then leaving with the event. The difference between a “street closure” and a “vehicle-stopping layer” is documentation. Traffic-control tools manage movement. Crash-tested systems document how […]
Bollards and Barriers for Parking Garages and Ramps: Practical Protection at Exits, Pay Areas, and Retail
Why parking garages need a different approach In most facilities, vehicles and pedestrians can be separated with distance. Garages compress everything: turning movements, ramps, columns, doors, and queue lines. That means the same site can have two different impact problems. One is common and low-speed, like a driver misjudging a turn at a ramp end. […]
