Industry Leading Durability
Our 40 mils thick Aluminum signs have a 7-year outdoor warranty, but most signs last much longer. Our Trespassers Shot Sign is laminated for enhanced performance. You can clean off graffiti and your graphics are protected. Unlike many other signs, our No Trespassing - Construction Area Bilingual signs use industry-leading 3M inks and not off-brand or other low-durability inkjet 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.

Don't Scrimp on Quality
We do not compromise with the quality of our signs and suggest even you shouldn't. Signs from competitors without a laminate start to fade in two to three years when exposed to the sun, moisture, and rain in the US. Also, most digital inkjet presses used by smaller sign shops only use a little amount of pigment on the sign, better suited for posters or banners, but not outdoor signage. Our 3M inks, laminate, and thick, rust-proof material ensures years of durability required for outdoor signage. We have been making outdoor signs for over 100 years – so we know which type of signs will last.
