DURABLE ALUMINUM: 'Work Zone Ahead' signs are made of 80 mil thick heavy-duty rustproof reflective and laminated aluminum that easily lasts 10 years outside and meets DOT road and traffic requirements.
EASY INSTALLATION: All signs come with rounded, burr-free corners and pre-punched and pre-cleared holes for quick installation. Signs mount to U-channel posts, square or round galvanized posts, wooden posts, and chain-link fences.
3M AUTHORIZED: Signs use official 3M Reflective Engineer Grade film and are printed with 3M screen printing or 3M outdoor digital inks designed specifically for outdoor traffic and property signs - providing ultimate quality and assurance.
LAMINATED PROTECTION: With lamination, graphics are protected from weather and abuse to preserve a fresh look. Graffiti can be cleaned off too. Clear UV laminate resists chemicals, UV rays, water, and abrasion.
