Our drop-down barriers (steel or aluminum construction) are unobtrusively located above the head of the opening, ready to be lowered at a moment’s notice. This system is perfect for areas where conventional swinging or sliding of a gate can’t work.

Automatic sensors can operate the barrier with rising flood waters, or push button operation keeping you in control.

Direct drive electric motors smoothly and precisely lower the barrier in to position and firmly lock it in to place to form an efficient, dependable flood protection.

Safety is a key factor in this design and all motors have a 'free-fall', dead-stop braking system built-in as standard. In addition, all systems are installed with a pulley system that overrides the motorized drive and allows the flood barriers to be manually lowered and raised in safety.

As optional features, the systems can be activated remotely, triggered by water or smoke detection or by security alarm systems. Touch and motion sensors can also be added to the braking system whilst further security is available in the form of audio/visual alarms, warning as the flood barrier moves.

A 24 volt back-up system ensures that the flood barrier will operate in the event of a mains supply failure.


Barriers can be mounted behind building facades making them as desirable in prestigious locations (such as hotel lobbies, sport arenas, shopping centers and office buildings) as they are essential in factory entrances and loading bays. We build standard drop-down systems up to 2.1m (6ft) in height and 6.0m (19ft) in length. Multiple systems can be linked together.
