## Description

Reflective Signs Are Hard to IgnoreOur aluminum signs have a reflective surface for extra visibility in dark and dim light conditions. Reflective surface means light thrown from headlights will reflect back making the sign more readable.3M Engineer Grade [“EG”] Reflective3M Engineer Grade reflective signs are the most common material found on our public roads. 3M Engineer Grade signs have up to 7-year outdoor warranty.USA’s Oldest Sign ManufacturerFamily owned since 1918, we take immense pride in our signage. Being one of the oldest certainly means we know this business in and out. Our South Dakota factory is the oldest manufacturer of metal signs in the USA. We have been an integral part of safety and convenience our road signs have provided over the years.Industry Leading Durability3M Engineer Grade signs have a 7-year outdoor warranty, but most signs last much longer. Our 80 mil thick signs are laminated for enhanced performance. You can clean off graffiti and your graphics are protected. Unlike many other signs, our Road Closed signs use industry-leading 3M inks and not off-brand or other low-durability inkjet pigments that fade in a year or two.
