4m Concrete Safety Barrier - Delta Bloc DB80

Delta Bloc DB80 4m Concrete Crash Barrier is a high-strength, precast concrete safety barrier designed for superior vehicle containment and protection in roadworks, infrastructure projects, and traffic management applications.

The Delta Bloc DB80 4m Concrete Crash Barrier is a high-strength, precast concrete safety barrier designed for superior vehicle containment and protection in roadworks, infrastructure projects, and traffic management applications. As part of the internationally recognised DB80 system, this 4-metre unit delivers proven crash performance, modular flexibility, and reliable durability in both temporary and permanent installations.

Engineered with a reinforced F-shape profile and a patented coupling system, the DB80 barrier is designed to manage impact forces efficiently by allowing controlled deflection and energy absorption during collisions. This helps reduce vehicle penetration and crossover risk, improving safety for both road users and worksite personnel in high-traffic environments.

The 4m DB80 barrier is MASH TL-3 tested and approved for use on Australian road networks, making it suitable for high-speed environments where strong vehicle restraint is required. Its precast modular design allows for fast installation and relocation using standard lifting equipment, while secure interlocking connections ensure continuous stability across barrier runs.
