Our 24" x 6" Aluminum Sign Blanks are manufactured from alodized aluminum and are not punched with mounting holes.
These sign blanks are fantastic. You won't find any better.
These blanks which are exactly the same as the current Chicago Street Signs, are of consistantly high quality with few if any scratches. Always well packed and unusually fast shipping. I have not been able to find a better price on the web or locally even with shipping costs.
