NEWFLAG Automatic flood barrier systems are designed for long service life with minimal maintenance so they will operate for decades.

NEWFLAG Automatic Flood Barrier which is hydrodynamic driven by rising flood water itself, can be customized in module supply form according to the doorway width at the site. It consists of the bottom frame, floating barrier panel with non-slip surface in the module supply, and the end sealing rubber attached to the side wall. The rising or retreating flood water will flip up or close down the barrier panel automatically and it does not require power or human to intervene. It can be also manually lifted by an adult due to its lightweight technology. The structure is designed simply to reduce the risk of failure and easy to repair or replace.

Installation Technical Requirements: the overall installation accuracy is 5mm, and ground flatness requirements are ≤3mm/m. According to the requirements of the site, it can be constructed in Ramp form directly sitting on the existing ground with speed bump attaching both sides(Product height when closed is approx.55-60mm above the ground); ②Embedded form with top surface flush to the ground by slotting the ground for containing space.

The weight of the lightweight barrier panel with great strength is about 18.5 kg/Square Meter which can withstand the crush of vehicleweights 4.2 metric tons. We can customize the barrier panel for the requirement even for container trucks.
