Our 80 mils thick Aluminum signs have a 10-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 Slow - No Dust 5 MPH Maximum signs use industry-leading 3M inks and not off-brand or other low-durability inkjet pigments that fade in a year or two.
