High-Intensity Prismatic sheeting

Article By Lianxing Operations Director and Reflective Material Expert   For decades, standard Engineering Grade (EGP) glass-bead reflective sheeting was the default choice for traffic signs worldwide. However, a massive optical shift is underway. Driven by the demands of autonomous driving technologies (ADAS), aging driver populations, and stricter global safety mandates, modern highway infrastructure is rapidly phasing out legacy materials.   Today, securing government bids and long-term highway contracts requires an upgrade to High-Intensity Prismatic (HIP) and Diamond Grade reflective sheeting. Here is a deep dive into the technology driving this shift and how to align your procurement strategy with the latest ASTM D4956 standards. The Core Difference: Glass Beads vs. Micro-...
