Engineer grade, HIP, and microprismatic — how we name grades.

Marketing grade names help buyers navigate. ASTM D4956 Type is a performance classification confirmed per SKU. “Diamond Grade” is a 3M trademark and is not used as our category name.

Engineer grade

Typically glass-bead construction for commercial and general signing. Cost-effective; confirm Type on the TDS.

High intensity prismatic (HIP)

Prismatic constructions for brighter regulatory and warning signs. Procurement queries often use HIP or high intensity prismatic.

Microprismatic high performance

Higher-performance cube-corner products for demanding geometries. Exact Type and RA tables stay per SKU.
