Be safe against vehicles
Strong barriers and fences
Stalwart offers multiple anti-ram ratings. Each installation can be designed with the most appropriate stand-off distance from the assets. The Stalwart framework is a raceway for wiring, conduits, and/or security cabling required around the perimeter of a project. This integrated design eliminates the need for costly trenching and boring, becoming a value-added solution for perimeter security upgrades.

More information
What are crash ratings?
Crash ratings are given to products that are designed to stop vehicular attacks in order to determine their effectiveness. Typically crash ratings are determined by three factors:
- How heavy the vehicle is
- How fast the vehicle is travelling
- How far past the barrier the vehicle travels
M-Ratings (new ratings)
The new M-ratings have since replaced K-ratings and are governed by the American Society for Testing and Materials (ASTM). The primary difference is that certification is given based on how far the payload travels past the barrier. Additionally there is no limit to how far the vehicle can travel past the barrier to be certified. According to the ASTM, anything that travels beyond 98.41′ can be given a P4 certification.
K-Ratings (old ratings)
The K-ratings were first developed in 1985 (revised 2003) by the Department of State. The product was given certification based on how far the front bumper of a 15,000 lb. vehicle travelled past the barrier. The K-ratings also limited certification to 50′ or less past the barrier.
