The Detectable Warning Plate is a detectable warning surface designed for use by individuals who are blind or have low vision. Made of cast iron, the plate is durable and adheres to concrete without wearing, pealing, cracking or delaminating. The measured coefficient of friction is 0.9. The cast iron material can withstands snow plow abuse. The unit is installed into prepared concrete with reusable lifting springs. Upon exposure to moisture, the unpainted cast iron plates forms a temporary iron oxide scale. Following this, the plate darkens to a permanent patina. OPTIONS: Powder coat paint. COLOR: Natural metal (standard); optional paint includes Federal yellow, dark gray, or brick red.
