Neenah Recommends Unpainted Plates

Neenah Recommends Unpainted Plate:
Upon exposure to moisture, the cast iron plates will form a temporary iron oxide scale, which is a normal part of the oxidation process. Following this, your warning plate will darken to a patina, which is permanent throughout the life of the installation. Look at manhole covers in the street to see how the color matures.
