Facility perimeters that face high-speed vehicle threats require barriers with verified stopping power. Barrier1 Systems’ M50 portfolio delivers proven ASTM F2656 crash-rated performance through two advanced engineering approaches: the Hercules M50 deep-mount system with no-rebar installation and the Tomahawk M50 shallow-mount system, both included on the DoD Anti-Ram Vehicle Barrier List.
These systems combine certified crash-rated protection with installation flexibility that accommodates curved perimeters and complex roadway configurations without compromising performance. Crash-tested M50 bollards are ideal for government buildings, power plants, data centers, and other critical infrastructure.

M50 Performance Standards and Testing Protocols
The M50 designation is more than an incremental step above ASTM M40 ratings. The M50 classification addresses scenarios where vehicles may achieve substantial speeds before impact. These situations overwhelm lower-rated barriers and compromise facility security. The test protocol simulates these conditions using controlled parameters and real-world vehicles that replicate worst-case attack scenarios.
Current ASTM F2656 M-rating standards establish testing criteria using 15,000-pound medium-duty trucks at precisely controlled speeds. The M50 classification requires successful barrier performance against 50 mph impacts, representing the upper threshold of vehicle barrier testing under existing protocols. Barrier1 Systems’ crash-rated M50 class security bollards achieve these levels with a combination of mass and engineered impact distribution.
Barrier1 Systems’ M50 Crash-rated Bollards
| System | Best application | Foundation Depth | Penetration Rating | DoD List Status | Key Advantage |
|---|---|---|---|---|---|
| Hercules M50 | Moderate standoff distances | 36 inches | P2 (3.3-23 ft) | DoD Listed | No-rebar installation innovation |
| Tomahawk M50 | Close-proximity asset protection | 14 inches | P1 (≤3.3 ft) | DoD Listed | Stand-alone shallow-mount bollard (no array required) |
For facilities requiring maximum perimeter security, M50-rated systems provide the performance assurance necessary when barrier failure could result in serious security consequences. Barrier1 Systems’ dual approach addresses both shallow-mount constraints and deep-mount optimization while maintaining M50 protection levels.
Hercules M50: Maximum Security with Efficient Installation
The Hercules M50 (Model SPB-1200) eliminates traditional foundation complexity while delivering certified M50-P2 performance. The system utilizes internal vertical rebar within the 10¾” OD steel bollard structure for impact distribution. This design requires no rebar in the foundation and uses a set-and-pour methodology with standard 4000 PSI concrete in the 36-inch foundation excavation. No field welding, bolted connections, or specialty subgrade are required during installation.
No-Rebar Foundation Design Advantages
| Traditional High-Security Barriers | Hercules M50 No-Rebar System |
|---|---|
| ❌ Field rebar installation required | ✅ No rebar in foundation |
| ❌ Multi-trade coordination needed | ✅ Reduced trade coordination requirements |
| ❌ Specialty equipment required | ✅ Standard excavation equipment |
| ❌ Weather-dependent rebar work | ✅ Streamlined concrete placement |
| ❌ Longer installation timelines | ✅ Reduced Installation time |
| ❌ Higher labor costs | ✅ Reduced installation costs |
Independent crash testing validated the Hercules M50 (SPB-1200) using a 15,000-pound truck at a 50 mph impact speed. The system successfully met ASTM F2656 M50/P2 requirements, stopping the vehicle with controlled penetration while maintaining structural integrity and demonstrating its effectiveness through a simplified no-rebar foundation design.
Tomahawk M50: Stand-Alone Shallow-Mount Protection
The Tomahawk M50 (Model SMB-1200-SA) addresses critical installation constraints through shallow-mount engineering that achieves M50-P1 performance with only 14-inch embedment. Unlike many shallow-mount systems that require an array to achieve certification, the Tomahawk M50 is a single, stand-alone bollard that provides full crash-rated protection in space-constrained environments. Its design makes it ideal for sites with utilities, high water tables, or limited excavation depth where deep-mount systems are impractical.
Shallow-Mount Engineering Benefits
| Installation Challenge | Deep-Mount Limitations | Tomahawk M50 |
|---|---|---|
| High Water Tables | Cannot accommodate | 14-inch foundation |
| Underground Utilities | Require expensive relocation | Utility-friendly shallow installation |
| Urban Environments | Limited installation capability | Dense infrastructure accommodation |
| Geological Constraints | Shallow bedrock prohibits installation | Bedrock-compatible embedment |
| Array Requirement | Not applicable (deep-mount bollards are certified individually) | Stand-alone bollard achieves full crash rating |
Independent testing at Calspan validated this approach using a 15,150-pound truck at 48.60 mph impact speed. Vehicle payload penetration measured 772mm and 841mm for left and right leading edges, respectively; effectively zero intrusion beyond the barrier line despite minimal foundation depth.
System Selection: Choosing the Right M50 Solution
Selecting the optimal M50 bollard system requires careful evaluation of site-specific constraints and installation parameters. Traditional M50 barriers typically require complex rebar coordination, extended installation timelines, and limited flexibility for challenging site conditions, making Barrier1 Systems’ portfolio advantageous for most applications.
The decision between Hercules M50 deep-mount and Tomahawk M50 shallow-mount systems depends primarily on underground infrastructure and site limitations. Sites with standard excavation capabilities and adequate foundation depth benefit from the Hercules M50’s prefabricated, no-rebar installation efficiency. Locations with utility conflicts or geological constraints are best served by the Tomahawk M50’s stand-alone shallow-mount design, which achieves full crash rating without requiring an array. Both systems are included on the DoD Anti-Ram Vehicle Barrier List, ensuring recognized compliance for federal and high-security projects.
Installation Complexity Comparison
| Site Constraint | Traditional M50 Barriers | Hercules M50 (Deep-Mount) | Tomahawk M50 (Shallow-Mount) |
|---|---|---|---|
| Foundation Depth Available | 36+ inches with rebar coordination | 36 inches required | 14 inches required |
| Underground Utilities | Extensive coordination and potential conflicts | Requires clearance verification | Minimal utility conflict |
| Soil Conditions | Limited adaptability to challenging conditions | Standard soil requirements | Accommodates challenging conditions |
| Water Table Level | Deep water table with complex foundation prep | Deep water table needed | High water table compatible |
| Federal Compliance Priority | Variable DoD acceptance | DoD Listed | DoD Listed |
| Penetration Requirements | Variable ratings available | P2 crash rating | P1 crash rating |
Perimeter Security Applications: When M50 Becomes Essential
Facilities near highways, critical infrastructure, and federal sites often require M50 protection. In these cases, the higher cost is justified by the risk of catastrophic failure. The choice between deep-mount and shallow-mount systems depends on site constraints, foundation capabilities, and installation timeline requirements.
High-security scenarios justify M50 investment when barrier failure consequences exceed incremental costs compared to M40 alternatives, particularly for embassy compounds, critical infrastructure, and military installations where protection standards cannot be compromised.
- Embassy and Diplomatic Installations often require M50 systems where international security protocols mandate maximum protection with minimal standoff distances. Urban locations often require shallow-mount solutions due to utility constraints.
- Critical Infrastructure Protection, including power generation facilities and data centers, utilizes M50 systems when successful vehicle penetration could cause a regional or national impact. Deep-mount installations are often selected where foundation conditions allow.
- Military and Defense Facilities specify certified M50 systems for base perimeters and critical asset protection. Inclusion on the DoD Anti-Ram Vehicle Barrier List ensures recognized compliance for federal procurement and construction projects.
- Corporate High-Security Applications protect executive facilities and research installations where security failures could compromise competitive advantages or operational continuity.
