Pipeline Markers & Cathodic Protection Test Stations
UV-Stabilized HDPE Tubular Pipeline Markers
Step-Ko Pipeline Markers provide high-visibility identification and essential cathodic protection monitoring for buried gas, water, and utility lines. Our UV-stabilized HDPE and fiberglass markers are vandal-resistant, maintenance-free, and designed to withstand harsh environmental conditions while preventing accidental pipeline damage.

High-Visibility Aerial & Ground Observation Markers
The PipeMarker Observation Markers are made of a weather resistant aluminum frame that includes extra cross supports. These observation markers each come standard with up to four, 13” extra high vinyl numbers that comes with a minimum of fifteen years of outdoor life. The numbers can be customized to be extra reflective and can come in any color imaginable as well as the high gloss, clear coated background.
The PipeMarker Observation Marker is extra sturdy, consisting of a dual loop mounting system to prevent “wind whip,” twisting, and most of all, tampering. Everything is bolted using 18-8 Stainless Steel Bolts and Flange Lock Nuts which eliminates worries of broken welds in the field.
