The AutoSeal Watertight Roller Curtain Door is the latest technology in flood protection.  During normal non-flooding operation, it functions as an overhead roller curtain door. Once water is sensed by the controls at a pre-determined level, it automatically deploys and secures the opening. Alternately, a press of the button sets the door in the flood protection mode.

The door is constructed from aluminum roller curtain door slates with a stainless steel frame and a flush bottom sill. It is provided with a battery back-up for operation when power is lost. Like most standard garage doors, it has an infrared start/stop sensor to avoid closing when an object is in the way.

Applications include warehouses, entrance doors, storefronts, garage doors, parking lots, etc

Horizontally Sliding Flood Barriers:
our horizontally sliding barriers are available in several different designs, allowing us to make sure that you get the best product for your application. Almost all of these barriers can be opened and closed in seconds by one person. A wide variety of gaskets can be used depending on the application, including lipseal, '"P'" gasket, standard compression gaskets or inflatable seals. Extremely large and heavy barriers can be supplied with winches or towing points to assist with opening/closing of the gate, as well as to provide a measure of safety when opening or closing the gate in extreme wind conditions.

Vertically Sliding Flood Barriers:
Especially suited to loading docks and warehouses, vertically sliding flood barriers are a great way to close off large opening. The panels are raised and lowered with the aid of manual or power winches. All vertically sliding barriers are supplied with a hold-open device for safety purposes.
