Aesthetic Appeal

  • Recommended to be furnished and installed in their natural unpainted state for best long-term, maintenance-free performance and aesthetic appeal
  • Unpainted plates will develop a permanent patina that will remain the same throughout their lifetime
  • Powder coat paint is available upon request. Most common colors are federal yellow, dark gray and brick red.

Coefficient of Friction
Excellent non-skid characteristics comply with all ADA and ABA guidelines. The measured coefficient of friction is 0.9.

Neenah Recommends Unpainted Plates:
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.
