PS Industries Incorporated (PS Flood Barriers)
A Midwest manufacturer whose flood line was born out of the 1997 Red River flood that hit its own city, and the only company in this category whose FM Approval is stated as an actual certification rather than as a marketing comparison. Acquired ILC Dover's Flood Pro line in January 2023, so the former Flex-Wall and Flex-Gate products now sit here.

Our verification notes
Read the certification at the model level, not the company level. The same manufacturer's FP-535 wall system is only 'designed and tested to meet' the standard, which is not an FM Approved listing - so 'FM Approved' is a property of specific SKUs, never of a brand. We could not independently confirm the listing in the FM Approvals guide because that database blocks automated access; the wording above is the manufacturer's, quoted precisely. Verified projects are in Iowa and Michigan; no Indiana installation was found. Sells factory-direct with no Midwest dealer network.
