TCRB-12 (M50/K12) Manual Crash Rated Beam
Product Notes
- TCRB-12 (Manual Operation) closes single clear opening widths up to 20 feet.
- For larger clear opening widths, the TCRB-12-EMLA (Electro-Mechanical) and TCRB-12 (Hydraulic) close single clear openings up to 24 feet.
- Custom sizes and options are available. Check with manufacturer.
Product Summary
The TCRB-12 (Manual Operation) is ASTM F2656-07-M50-P1 certified (equivalent to U.S. Department of State K12). Will stop a 15,000 pound vehicle traveling at 50 mph within 1 meter. Components include steel stanchions and an aluminum beam containing proprietary engineered cabling. For ease of operation the system is counterbalanced.

Frequently Asked Questions
TYMETAL has been in the perimeter security solutions market since 1985. With more than three decades of experience designing, manufacturing, and installing the TCRB-12 (M50/K12) Manual Crash Rated Beam, we have encountered many questions along the way. Explore a few of the common questions we are asked below. If you don’t find the answers you’re looking for, feel free to contact us by phone at 888-978-4283 or online.
What K12 crash rating standards and vehicle speeds does the TCRB-12 beam system withstand?
The TYMETAL TCRB-12 is certified to U.S. DoS K12 standards equivalent to ASTM F2656 M50/P1, confirming it stops a 15,000-lb vehicle at 50 mph within a 1-meter penetration distance. This is TYMETAL’s highest crash-rated barrier arm product and is specified for military bases, embassies, border crossings, and critical infrastructure requiring maximum vehicle threat mitigation.
How does the TCRB-12 design differ structurally from the TCRB-4 K4 model?
The TCRB-12 uses substantially heavier structural aluminum beam sections, a more robust hinge and pivot system, and a larger hydraulic operator assembly than the TCRB-4. The foundation post and anchor system is also significantly deeper and more reinforced, reflecting the roughly 10-fold increase in kinetic energy that the K12 system must absorb compared to K4.
What foundation depth and anchoring specifications ensure full K12 compliance?
Full K12 compliance requires the TCRB-12’s posts to be embedded in TYMETAL-engineered reinforced concrete foundations with specific depths, dimensions, and rebar layouts derived from the M50/P1 crash test parameters. These specifications are non-negotiable for certification validity — any deviation must be reviewed and approved by TYMETAL’s engineering team before installation.
Can this beam integrate with access control systems?
Yes. The TCRB-12 operator control panel supports standard access control interfaces including guard booth controls, card readers, vehicle loop detectors, and remote operation systems. The system can be integrated into facility-wide security management platforms through standard relay and communication interfaces provided in the operator control documentation.
What inspection and replacement procedures follow a crash impact?
Following any vehicle impact, the TCRB-12 beam, hinge system, operator, and foundation must all be taken out of service immediately and inspected by TYMETAL-qualified personnel. Structural components that have absorbed impact energy must be replaced with TYMETAL-specified parts even if visual damage is not apparent, as internal deformation can compromise future crash performance. Full re-commissioning and certification documentation is required before return to service.
