Product identification marker configured as an indicator plate for storage tanks under ground and above ground

摘要

An indicator plate is provided which is embedded in the ground adjacent an inlet to a storage tank. The indicator plate is formed from materials which can support vehicular traffic directly thereupon without degradation of indicia located upon a top surface of the indicator plate. The indicator plate is formed from two separate molds. A first mold forms indicators. These indicators are then placed within a second mold which is then filled with fluid material in a manner which allows the indicators to be exposed through a top surface of the plate after the material hardens. A bolt is also placed within the material before hardening for anchoring the plate to the ground adjacent the inlet to the storage tank.
