| Safety |
✅ Active buffered braking Smooth stopping via wheel-lift & friction, reducing injury risk. |
❌ Rigid collision High risk of severe vehicle damage and personal injury. |
⚠️ Minimal interception capability Warning function only; vehicles can easily knock them over. |
❌ Rigid barrier High impact force, prone to secondary accidents. |
| Portability |
✅ Lightweight & flexible 25kg with wheels, deployable by one person. |
❌ Extremely heavy Requires machinery for movement, no quick response. |
⚠️ Lightweight but no wheels Still cumbersome to move, can shift in wind. |
❌ Completely fixed Not movable, requires construction for installation. |
| Deployment Speed |
✅ 3 min/set Ready to use immediately, no tools needed. |
❌ Hours-level Requires lifting equipment, time and labor-intensive. |
⚠️ 10-15 min/unit Requires filling with water/sand, low efficiency. |
❌ Permanent installation Requires professional installation, not for temporary use. |
| Adaptability |
✅ Foldable + casters Adapts to various terrains, adjustable with project progress. |
❌ Fixed position Difficult to adjust once placed. |
⚠️ Movable but unstable Prone to tipping, unsuitable for curves/slopes. |
❌ Completely fixed Cannot be adjusted as needed. |
| Visibility |
✅ High-vis yellow + LED compatible Conspicuous day and night. |
⚠️ Typically grey/white Poor nighttime recognition. |
✅ Reflective but gets dirty Fades easily with long-term use. |
⚠️ Requires separate reflective strips Warning effect depends on add-ons. |
| Durability |
✅ Aluminum + electrostatic coating Corrosion-resistant, lifespan ≥5 years. |
✅ Strong but prone to cracking Difficult to repair. |
❌ Plastic degrades easily Becomes brittle under sun exposure. |
✅ Strong but requires rust prevention High maintenance cost. |
| Overall Cost |
✅ One-time investment, long-term use Simple maintenance, reusable. |
⚠️ Low unit price but high hidden costs High costs for handling, storage, and replacement if damaged. |
⚠️ Low unit price but short lifespan Frequent replacement, high long-term cost. |
❌ High installation & maintenance costs Highest total investment. |
| Eco-friendliness |
✅ 100% recyclable aluminum Low energy consumption in production. |
⚠️ High energy cement Becomes construction waste if damaged. |
❌ Hard-to-degrade plastic Significant environmental pollution. |
⚠️ Steel recyclable but energy-intensive High carbon emissions in production. |
