We offer two sheeting options on parking signs:
High Intensity Prismatic (HIP) meets ASTM D4956 Type IV. This is the standard choice for most parking sign installations. It provides strong nighttime reflectivity and meets the requirements of nearly all municipalities and property management standards.
Diamond Grade (DG3) meets ASTM D4956 Type XI and returns nearly twice the light of HIP. Choose DG3 for signs on busy roadways, poorly lit areas, or locations where maximum nighttime visibility is critical.
For parking lots and private facilities, HIP is the most common and cost-effective choice. DG3 is typically specified for signs installed along public roadways.
