Our R7-5 one-hour parking with right arrow traffic signs are manufactured to M.U.T.C.D. and F.D.O.T. specifications, where applicable. All traffic signs are available in Engineer, High Intensity, and Diamond grade reflective sheeting. New federal requirements require minimum levels of reflectivity on traffic signage. This may result in a minimum reflectivity grade of High Intensity or greater. Traffic signs are constructed of a Heavy Duty 0.063, or 0.080 gauge Alodine treated Aluminum, for maximum exterior life. We can fabricate any standard and custom signage. For any signs, not shown, please contact our sales department for a quote.
