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 Crash-Rated Fences, 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 crash standards do TYMTEAL crash-rated fences meet?
TYMETAL crash-rated fence systems are tested and certified to ASTM F2656 and U.S. Department of State K-rating standards, with products available at K4 (M30), K8 (M40), and K12 (M50) certification levels. These ratings confirm the fence will stop a vehicle of specified weight traveling at a defined speed with minimal penetration distance.
How are fence posts and rails engineered to absorb vehicular impact?
TYMETAL crash-rated fence posts are fabricated from heavy structural steel sections embedded in reinforced concrete foundations engineered to resist pullout and moment forces during a vehicle strike. The rail and infill system is designed to transfer impact energy laterally through the fence line and down into the foundation rather than allowing localized failure or panel penetration.
Can crash-rated fencing be combined with gate systems or barriers?
Yes. TYMETAL crash-rated fence systems are designed to integrate with matching crash-rated gates, bollards, and beam barriers to create a unified certified perimeter. The fence and gate systems are rated to compatible standards so the entire perimeter achieves consistent vehicle impact resistance without creating weak points at transitions.
What types of finishes or coatings are used for long-term durability?
TYMETAL crash-rated fences are available with hot-dip galvanizing, powder coat finishes, and combination coating systems suited for high-corrosion environments including coastal and industrial sites. These finishes protect the structural steel from rust and degradation while maintaining the mechanical properties required to sustain crash performance over the service life of the installation.
What inspection and repair procedures follow an impact event?
Following any vehicle impact, the affected fence section, posts, and foundation anchors must be professionally inspected before the barrier is considered operational. Bent or deformed structural members must be replaced — not straightened — to restore certified crash performance. TYMETAL provides replacement component specifications and can support post-impact engineering review.
