• Heavy-duty Aluminum Signs will not rust • Reflective sign face provides added visibility in low-light conditions • UV-resistant inks prevent fading during long-term outdoor use • Supplied with top and bottom center holes for post- or fence- mounting Choose from 3 reflective finishing materials: Engineer-Grade Prismatic (RA)- Economical prismatic sheeting provides better day and nighttime brightness than traditional beaded Engineer-Grade sheeting. This micro-prismatic retroreflective sheeting is recommended for commercial sign applications as well as non-critical traffic control signs, regulated by the MUTCD. Meets ASTM D 4956 Type I. High-Intensity Prismatic (HP) - 3X brighter than Engineer-Grade Prismatic. Non-metalized micro-prismatic lens reflective sheeting is effective for daytime, nighttime and artificial light conditions. Provides durability and long-term reflectivity. Meets ASTM D 4956, Type III, Type IV, and Type X. DG High-Prism (DP) - 10X brighter than Engineer-Grade Prismatic. Provides the highest level of reflectivity and maintains great visibility and reflectivity from far away and at wide angles. Meets ASTM Type IX
