All our object markers are available in 80 mil thickness. Type 2 Object Markers (X-OM2-2H and X-OM2-2V), though, are available in 63 mil Engineer Grade Reflective aluminum too, along with the 80 mil variants. Made of industrial-grade, heavy-duty, rustproof aluminum, the markers do not bend or warp. Both Hi-Intensity and Diamond Grade Reflective Aluminum Signs are available in the same 80 mil thickness. Guaranteed to last for 12 years outdoors, this aluminum gauge will easily withstand harsh weather conditions, storms, winds, and abuse.
