Industry Leading DurabilityOur 40 mils thick Aluminum signs have a 7-year outdoor warranty, but most signs last much longer. Our signs are laminated for enhanced performance. You can clean off graffiti and your graphics are protected. Unlike many other signs, our Restricted Area - Monitored by Video Camera 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 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 Photography Sign and others have provided over the years.Don’t Scrimp on QualityAs the largest sign manufacturer and distributor in the country, we don’t compromise with the quality of our signs and neither should you. Competitor signs come without protective lamination and start to fade in two to three years when exposed to weather abuse. We, on the other hand, manufacture all our outdoor signs with laminate that makes them graffiti and fade-proof. Also, most digital inkjet presses used at smaller sign shops only use a small amount of pigment on the sign. Since we are in this business for over 100 years now, we use only branded 3M inks in generous quantities which can make a world of difference in signs.
