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 popular signs preferred for regular use on public roads and indoors. They make the message visible and legible in dark.

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.

Industry Leading Durability
3M Engineer Grade Aluminum signs have an outdoor warranty of up to 7 years, but most signs last much longer. Our 63 mil thick signs are laminated for enhanced performance. You can clean off graffiti and your graphics are protected. Unlike many other signs, our Please Keep Gate Closed At All Times signs use industry-leading 3M inks and not off-brand or other low-durability inkjet pigments that fade in a year or two.
