Wholesale Access Panels and Access Doors For Commercial Buildings Access panels and access doors play a major role in a commercial building. They can easily be installed in a wall or ceiling allowing personnel to open or close the access point in order to gain access to what is behind the wall or above the ceiling. Many access doors can be seen on tile ceilings or plaster walls. There are many types of access panels and access doors to choose from, each serving it's own special purpose. For example, we offer flat frame steel security access panels, which are great in detention or security applications, where the access panel can only be opened by authorized personnel. Likewise we also offer tile ceiling access panels, which are great for commercial buildings, where electricians or maintenance personnel need access above the tile ceiling. By having a tile ceiling access panel or access door, the personnel will not have to constantly remove ceiling tile, which can be messy and very damaging to the ceiling tile.
