What grade of aluminum is used to make road sign blanks?
We offer aluminum sign blanks in two alloys, 5052-H38 and 3105-H191. We carry multiple guages (thickness) including .040", .063", .080", .100", and .125". All aluminum is processed in-house to better control quality. We level, treat, cut, punch and radius aluminum coils into road sign aluminum blanks, all within our 65,000 square foot production facility.
