Reflective Signs Are Hard to Ignore
Our aluminum signs have a reflective surface for extra visibility in dark and dim light conditions. Reflective surface means light thrown from headlights or flashlights will reflect back making the sign more readable.

3M Engineer Grade [“EG”] Reflective
3M Engineer Grade reflective signs are the most common material found on our public roads. 3M Engineer Grade signs come with a 7-year outdoor warranty.

USA's Oldest Sign Manufacturer
Family 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 Gate sign has provided over the years.

Industry Leading Durability
3M Engineer Grade signs has 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 Approach Slowly - Automatic Gate Will Open sign uses industry-leading 3M inks and not off-brand or other low-durability inkjet pigments that fade in a year or two.
