Heavy-duty and crash-rated bollards: what do the terms mean?
A thicker-looking post does not prove impact performance. Ask for the exact product test evidence and the required installation.
Published 28 September 2026 · Bollards & Barriers
“Heavy-duty”, “anti-ram” and “crash-rated” can appear together in product descriptions, but they do not mean the same thing. If the job has a defined impact requirement, the specific product and how it is installed matter more than the marketing label.
Heavy-duty describes a product category
A heavy-duty bollard may be larger or more substantial than a simple parking post. That alone does not tell you what vehicle impact, if any, it was tested to withstand. A visible deterrent for a driveway and a barrier specified for a high-risk commercial site are different purchases.
Impact-rated means there is test evidence
For a stated rating, ask which exact model was tested, against which standard, with what vehicle mass and speed, and what the resulting performance was. The National Protective Security Authority’s impact-rated barrier catalogue lists tested vehicle security barriers and advises care when selecting and specifying them. A rating for one model should not be assumed to apply to another post in the same range.
The foundation belongs in the specification
The tested installation has particular foundation details. Ground depth, buried services and the surface at your site may prevent that arrangement from being reproduced without a revised design. The NPSA’s foundation guidance explains why changes from the tested foundation require careful assessment. For a project with a formal security requirement, the responsible designer should verify the product, layout and installation as a whole.
What should a buyer ask?
- Is the proposed post tested, or is “heavy-duty” only a description?
- Can you show the test report or certificate for the exact product?
- What foundation and spacing are required for the stated performance?
- Does the site allow those details to be installed?
- Does your insurer or project specification require a particular standard?
A domestic buyer may simply want a visible barrier behind a parked vehicle. If that is the goal, explain it plainly; you may not need a specialist rated system. If certification is required, agree the evidence before ordering. Compare fixed posts and retractable access only after deciding whether vehicles ever need to pass through the opening.
