Automatic Bollards

Cronax Automatic Bollards are heavy-duty vehicle access control systems designed to provide maximum security, traffic management, and perimeter protection. Engineered with high-strength steel and advanced hydraulic or electro-mechanical mechanisms, these bollards ensure reliable performance in even the most demanding environments. With quick up-and-down operation, Cronax Bollards effectively restrict unauthorized vehicles while allowing smooth passage for approved ones.

Our bollards are available in different impact resistance ratings (K4, K8, K12 crash standards), ensuring they can withstand high-velocity vehicle impacts. For added functionality, they can be integrated with access control systems, RFID, ANPR (Automatic Number Plate Recognition), or remote control operations. Designed with weatherproof construction, corrosion-resistant coatings, and built-in safety features like emergency manual override and reflective bands, Cronax Automatic Bollards guarantee long-lasting durability, visibility, and safety in all conditions.
