Swing-Hinged Flood Gates
Permanent Protection Engineered for Certainty
When flooding threatens your property, compromise is not an option. FRA swing-hinged flood gates are engineered to withstand Category 5 flood conditions, delivering lifetime durability and dependable protection for condominiums, parking garages, commercial facilities, and residential properties.
These gates offer robust flood defense and chemical containment for bunded areas and critical openings, and can remain permanently closed or be quickly deployed when needed.
How Swing-Hinged Flood Gates Work
Swing-hinged flood gates are permanently installed at vulnerable openings such as doorways, garage entries, loading docks, and building perimeters. When a flood event approaches, the gate swings into position on precision-engineered hinges and locks into place, forming a watertight seal. A single person can operate the gate without any special tools or equipment.
