We get a lot of questions about our sign blanks, but that's probably because we offer quite a few options to choose from. Previously in our Sign Blanks 101 series, we covered our Aluminum Sign Blanks and Reflective Sign Blanks. Today we’re going to talk about our Painted Aluminum Sign Blanks. 

Our Painted Aluminum Sign Blanks are just what you might imagine based on their name: pieces of aluminum with a glossy white painted finish on both sides. We find that our Painted Aluminum is more popular in custom signage applications since it does not feature the reflective base required for traffic signs, but we still cut our standard shapes with holes for mounting and radius corner cuts in accordance with the Federal Standard Highway Signs Manual.


Unlike our Aluminum Sign Blanks and Reflective Sign Blanks, Painted Aluminum is only available in one gauge and alloy: .063" gauge, 3105 alloy. We currently only carry white painted materials. Custom colors and painted finishes in other gauges and alloys can be achieved through powder coating our Alodized Aluminum Blanks to match your specifications. This is a custom process though, so give us a call for a quote if your project requires a little something special.

Here are some additional quick facts about our Painted Aluminum Sign Blanks: 
  • Production: all of our blanks are cut at our Bloomington, IN manufacturing facility, which means that we can cut just about any size and shape you need. 
  • Sizing: we list our sizes with the horizontal dimension first, followed by the vertical dimension. This is important because for most blanks, the size specification will determine where the holes are punched for mounting. A 12" x 18", for example, will have holes punched in from the 12" side, top and bottom centered, so that the sign is in "portrait" orientation. 
  • Phantom Points: signs with rounded corners are often sized using "phantom points". These points represent where the corner of the sign would be if the edge extended out from the side of the sign blank. On most shapes phantom points do not interfere with the sizing, but on triangle shapes it causes their actual measurements to be smaller than their "phantom measurements".
