Flat-surface markers used along buried utility routes or near roadways and access points for consistent visibility. Each marker is equipped with a vinyl label that’s overlaminated for superior defense against fading, moisture, and wear—so your warning message stays clear over time.
APWA Utility Color Code
To avoid confusion, the American Public Works Association (APWA) developed a Uniform Color Code used nationwide for utility markings. This standardized color system means that each color corresponds to a specific type of utility. Whether markings are paint, flags, or permanent posts, the colors stay consistent so everyone knows what buried lines are present.
