Industry Leading Durability Our 63 mils thick, rust-proof aluminum signs have a 10 year outdoor , but most signs last much longer. Unlike many other signs, our Private Property No Trespassing Signs use industry-leading 3M inks and not off-brand or other low-durability ink jet pigments that fade in a year or two. 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 signs have provided over the years.
