3M's "High Intensity" Grade reflective street signs offer up three times more reflectance than engineer grade reflective signs. Laminated for durability. Signs use 3M brand, "High Intensity" film, a prismatic technology. "High Intensity" film not only offers greater reflectance straight on, but is especially bright when approached from an angle. Tough 3M laminate resists weather and graffiti. Signs carry the 3M warranty for traffic signs - signs are guaranteed to last at least ten years outdoors - although in practice most signs last longer. Signs are printed with 3M screen printing or 3M outdoor digital inks designed specifically for outdoor traffic and parking signs. Unlike competitive signs, these signs are proven to last outside and use 3M matching ink and film components. Sheeting meets the standard DOT specifications for construction of Roads and Bridges on Federal Highway Projects FP-85 for Sheeting Type IIIA, Class 1 and the GSA LS-300C Reflectivity 2, Class 1. The base material for these signs is a 80 mil thick non-rusting aluminum. Signs have rounded corners - for easy handling and a professional appearance. Competitive signs often use lower cost (and more hazardous) square corners. Signs have prepunched / precleared holes to insure a hassle-free installation. Signs are sold in a pair. You receive two identical signs of each legend with printing on the front. They are then assembled together (around a pole) and fastened at the ends. This is the most durable and traditional of all street sign constructions.
