Anti-collision water-filled barriers are the thicker, more robust type in the water-filled barrier range, with stronger cushioning performance. They are specifically placed at road curves, intersections, toll stations, tunnel entrances, and other locations prone to collisions. Compared with standard barriers, anti-collision barriers have thicker walls and wider bodies, and weigh more after filling, effectively absorbing and dispersing vehicle impact energy to reduce accident severity and facility damage. Mold design focuses on uniform wall thickness, rib layout, water inlet and drain structure, anti-slip base design, and overall impact resistance to ensure the barrier does not crack, deform, or shift after impact. Overall advantages include strong anti-collision capability, effective cushioning, and high durability — ideal for road safety protection and temporary or long-term use at accident-prone sections.

In addition to municipal barriers, Jersey barriers, fence barriers, and anti-collision barriers, road barriers also include folding barriers, rotomolded barriers, blow-molded barriers, round barriers, square barriers, warning-light barriers, advertising barriers, and modular barriers. Folding barriers can be collapsed to save space when empty. Rotomolded barriers have thicker walls, better toughness, and longer service life, ideal for long-term use. Blow-molded barriers are thinner, lighter, and more cost-effective, suitable for temporary or short-term use. Round and square barriers suit flexible diversion and large-area fencing respectively. Barriers with warning lights or reflective strips improve nighttime safety, while advertising barriers can be used for commercial promotion. Modular barriers can be combined into fencing, isolation walls, or temporary passages, adapting flexibly to different scenarios. Overall, the choice can be made flexibly based on use case, isolation height, and budget.
