Abstract
An access floor panel includes a metal pan having a bottom and sidewalls. Lanced tabs extend from the bottom. A plurality of corner inserts include pad portions and core portions extending through the bottom. A concrete mixture encapsulates the tabs and insert core portions. The inserts cooperate with pedestal heads or plates to lock the panel to support pedestals. The panels also include silencer buttons. The buttons and inserts limit metal-to-metal contact. The inserts eliminate the need for stringers.
