Flange fence post has a flat base plate welded to the bottom, allowing it to be bolted onto hard surfaces such as concrete slabs, decks, or walls instead of being set in the ground. It is commonly used for installing fences on pavement or driveways, securing handrails or barriers on patios and decks, and setting up fence lines on rooftops or balconies.
