How to Choose the Right Bollard: Full Auto vs Semi-Auto vs Fixed
1. Full Automatic: Best for High-Traffic Entrances
Electro-hydraulic drive with 1.5-3.5s lift speed. 304 stainless steel, IP68 rated. Supports remote, APP, and PC control with license plate recognition and access control integration. Crash-tested by Ministry of Public Security (GA/T1343-2016). Column diameter 168/219mm, wall thickness 6-12mm customizable. Ideal for government compounds, military bases, airports — any 24/7 high-frequency vehicle access control.Full-auto models support emergency release on power failure: a manual hydraulic valve or backup battery lowers columns so emergency vehicles always pass — a key feature to confirm when specifying.
2. Semi-Automatic: Cost-Effective Middle Ground
Pneumatic rod drive, manual key operation — no external power needed. Internal spring mechanism auto-raises on unlock; manual press-down to lock. Same 304 stainless steel and IP68 rating with minimal maintenance. Ideal for fire lanes, pedestrian street entrances, residential side gates — low traffic, high reliability.Key management matters for semi-auto models: keep two or more key sets with a sign-out log; lost keys can be re-cut by the factory against the key code.
3. Fixed Bollards: Permanent Protection
Simplest and most affordable. One-piece 304 stainless steel permanently anchored to concrete foundation — no drive mechanisms or electrical components. 3M Diamond Grade reflective film for nighttime visibility. Ideal for building entrance protection, storefront barriers, gas station isolation — permanent physical deterrence.Fixed bollard layout also matters: continuous runs need clear gaps under 1.0-1.2m to prevent small vehicles squeezing through; staggered double rows further improve deterrence.
4. Selection Guide
Choose full-auto for daily high-traffic with system integration; semi-auto for low-frequency with high reliability; fixed for pure physical barriers.
