Grade Selection Guide — standard first, then grade

A decision table that starts from the standard your project is inspected against and the geometry the sign is read at, and ends with one grade — not with a range.

It names the two traps we see most: specifying Type XI for a car park that references Type I, and specifying Type IV for a gantry where the observation angle needs Type VIII. Both cost money and neither fails less.

The guide is the phone script our application engineers use. If the table does not resolve it, send the clause and the panel size and we will answer with one model.
