About This

3M AUTHORIZED. Official 3M reflective films and inks on durable, rustproof aluminum ensure that our signs meet all DOT requirements for outdoor parking and traffic signs.
REFLECTIVE. Signs have Engineer Grade reflectivity that makes sure they can be spotted at night.
DURABLE & LAMINATED. Heavy-duty rustproof aluminum has a 10-year outdoor durability rating backed by a 3M warranty. Graphics are protected from weather and abuse and graffiti can be cleaned off. Laminated signs outlast competitive unlaminated or overcoated signs.
INSTALLATION. With our signs, installation is a breeze. All signs have burr-free, rounded corners for safe handling and they come with pre-punched and pre-cleared holes for easy installation to chain link fences, walls, and doors.
MADE IN USA. We have been making signs for over 100 years in the US. We know which signs work and which signs are durable outside.
