ASTM F2656 · K-Rated · Anti-Ram
Installation, commissioning, and long-term service of certified perimeter security systems — supporting prime contractors and facility owners across the northern plains.
Capability
Crash-rated barriers only perform to their tested rating when they are installed exactly to the manufacturer's certified drawings — correct foundation depth and reinforcement, correct anchorage, correct sub-base preparation, correct commissioning. That is fabrication and site work, and it is what we do every day.
We install and service manufacturer-certified vehicle barrier systems as a specialty subcontractor. We are not the barrier manufacturer or the crash-test certifier — we are the crew that puts the certified product in the ground correctly, integrates the controls, proves it works, and comes back to keep it working.
Scope We Self-Perform
Ratings We Work To
Whether your submittal package calls it out in current ASTM terms or legacy Department of State K-ratings, we work from the certified drawings and the penetration rating your project requires.
| ASTM F2656 | Legacy DOS Equivalent | Test Condition |
|---|---|---|
| M30 | K4 | 15,000 lb medium-duty truck at 30 mph |
| M40 | K8 | 15,000 lb medium-duty truck at 40 mph |
| M50 | K12 | 15,000 lb medium-duty truck at 50 mph |
| P1 / P2 / P3 | — | Penetration rating: P1 is 3.3 ft or less past the barrier; P2 is 3.31–23 ft; P3 is 23.1–98.4 ft |
We also install low-speed surface-mount systems rated under ASTM F3016 (S-ratings) where site conditions rule out deep foundations, and work to DoD, UFC, and agency-specific anti-ram requirements as directed by the design team.
Systems
Crash-rated sliding gates — cantilever or track-mounted — plus swing, vertical pivot, and vertical lift gates for controlled entry points, integrated with the access control the facility already runs.
Shallow and deep-mount wedge barriers for active vehicle denial at guarded entrances, sally ports, and inspection lanes.
Automatic and manual retractable bollard lines for entrances that must open for authorized traffic and hold against everything else.
Crash-rated fixed bollards protecting building faces, utility equipment, fuel islands, pedestrian zones, and standoff perimeters.
Drop-arm crash beams and cable systems for long spans, secondary entrances, and perimeter runs where full barriers aren't required.
Non-rated barrier arms, loop detection, and lane control for the traffic-management side of the same entrance.
For Prime Contractors
If you are bidding or building a project in western South Dakota, Wyoming, Montana, North Dakota, or Nebraska that includes a crash-rated perimeter scope, flying a barrier crew in from out of region is expensive and slow. We are already here, with the equipment and the certified welders.
Facilities We Support
Federal buildings and courthouses · military installations and training areas · electric substations and utility yards · water treatment and pipeline facilities · data centers · airports and airfield perimeters · correctional facilities · mining and industrial sites · fuel and chemical storage
Ongoing Service
A wedge barrier that won't cycle is a gate propped open. Hydraulic systems, loops, and controls need scheduled attention, and most facilities in this region have no local service option — which means a fault becomes a security posture problem while everyone waits on a travel day.
