Aluminum Street Name Signs are available in the two metal types illustrated below — flat (.080, .100, or .125 GA thickness) and extruded. You choose the grade of sheeting which suits your needs and/or state/community specifications — 3M™ Engineer Grade, Prismatic High Intensity, or Diamond Grade3. Signs can be ordered single or double sided, with or without a border, with multiple color choices, on multiple styles/layouts. Both flat and extruded signs are available in 6" and 9" heights with lengths varying from 18" to 54" depending on the amount of text needed. Larger sizes are also available for 12", 15", and 18" heights at varying lengths.
