The NOR30 drop arm beam barrier is a powerful force protection product integrating quality with strength. The NOR30 drop arm beam barriers are tested and certified by the Department of State to the crash rating of K-4, capable of stopping a 15,000 vehicle traveling 30mph. The NOR30 provides a high level of security within a refined design. Upon impact, forces are first absorbed by the drop arm beam and then transmitted to the buttresses of the unit creating a vehicle barrier capable of protecting high security sites.
