When people evaluate a crash-rated vehicle barrier, they usually focus on the rating number. But I always ask one more question: What happens after the impact?

Standard bollard height usually falls between 36 and 48 inches above grade. Learn how visibility, ADA access, and ASTM crash standards shape the right height for your site.

At Delta Scientific, we manufacture and support both hydraulic and electromechanical vehicle barriers. We work with customers who specify each technology for different reasons, and we’ve seen successful installations of both around the world. That perspective has given us a front-row seat to the advantages, limitations, and long-term realities of each approach.

Learn where fixed bollards, portable barriers, and wedge barricades fit in a stadium security plan for plazas, VIP access, and loading docks.

Vehicles remain one of the most accessible and destructive threats a facility can face. This doesn’t change simply because new technologies exist. 

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.

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.

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.
