• This is the brightest sheeting produced by 3M, with three times the reflectivity of High Intensity and ten times the reflectivity of Engineer Grade.

• These signs combine the high daytime and twilight conspicuity with the high nighttime reflectivity and wide angle performance of 3M microprismatic lens technology

• Signs carry the 3M warranty for traffic signs - signs are guaranteed to last at least ten years outdoors.

• When you specify an orange or yellow sign in Diamond Grade, this material is actually fluorescent. Fluorescent yellow is approved by the U.S. Federal Highway Administration (FHWA) for use on all yellow warning signs such as no passing zone, stop ahead, yield ahead, and roadway alignment signs such as curve arrows and chevron signs. Fluorescent orange is commonly used in workzone areas. Both are exceptionally conspicuous and make your message hard to miss.
