Guaranteed- Patented graphic system molds signs directly into the GMC STAPERM™. The warning sign is guaranteed not to fade, peel or disbond for the life of the linemarker. All warning signs are custom designed for each utility or pipeline and conform to the spirit and letter of U.S. Department of Transportation Regulations 192.707 and 195.410.
Strong and Maintenance Free - Molded from engineering grade plastics, GMC STAPERM™has twice the impact resistance of aluminum, four times the resistance of PVC yet weighs 1/8 as much as a steel post. Unlike metal signs, GMC STAPERM™ will not corrode, shatter or peel. The integral color never requires painting to preserve its factory appearance. Maintains complete dimensional stability from -40 degrees F. (-40 degrees C.) to 175 degrees F (80 degrees C).
Safe - Non-conductive plastic drastically reduces shock hazard from induced current or short circuits. All plastic construction virtually eliminates impact damage to vehicles and people.
Colors - Red, Orange, Green, Yellow, Blue, Black and White are standard GMC Colors. Special colors to match company logos or other special requirements available by request. All colors are stabilized against ultraviolet attack and will not fade.
Sizes - Available in 2", 3", 4" and 6" nominal pipe sizes. Standard length is 6 feet. Special order lengths to 40 feet.
