Bollard Crash Ratings Complete Guide: ASTM, PAS 68, IWA 14-1 Explained Crash ratings are the foundation of security bollard specification. They tell you, in measurable engineering terms, exactly what a bollard can stop. Without a crash rating, a bollard is a decorative post with unknown performance....
Bollard Crash Ratings: The Complete Technical Guide to ASTM, PAS 68, IWA 14-1 Security bollards exist to stop vehicles. But not all bollards stop all vehicles, and the difference between a bollard that works and one that fails is not a matter of opinion—it is a matter of certified, measured, and doc...
Why 20cm Overlap Matters in Automatic Bollard Design When evaluating automatic bollards, most buyers focus on crash rating, rise speed, and diameter. But one design detail that separates reliable bollards from failure-prone ones is the overlap between the rising post and the ground sleeve. UPARK use...
20cm Overlap in Automatic Bollards: Engineering Detail That Prevents Failure Automatic bollards are precision machines buried in the ground. They operate in rain, snow, dust, and vibration, rising and lowering thousands of times over their service life. The difference between a bollard that lasts 15...
20cm Overlap Design in Automatic Bollards: The Complete Engineering Guide In the specification documents for automatic bollards, attention tends to cluster around three metrics: crash rating, rise speed, and operating voltage. These are the numbers that appear in product comparisons and procurement ...
When a security bollard needs to stop a vehicle attack, certification is everything. Three standards dominate the market: PAS 68 from the UK, IWA 14-1 internationally, and ASTM F2656 in the United States. They measure similar things but in different ways, and mixing them up can lead to the wrong pro...
