What is it?
Stairwell Flex-Gates (SFG’s) are high-strength, dry flood-proofing closure that can be deployed rapidly for flood mitigation of tunnels, doors or portals of any kind, and can fit openings of any shape, size or orientation; simple to operate and can be easily deployed or retracted in just a few minutes by a single person with very little training; increased reliability, with minimal maintenance, thus providing low life-cycle costs.
