We get a lot of questions about our sign blanks, but that's probably because we offer quite a few options to choose from. In the first post of our Sign Blanks 101 series, we talked about our Aluminum Sign Blanks. Today we’re going to cover our Reflective Sign Blanks. 

Traffic Signs are made reflective through the use of reflective sheeting material; this material is applied to one or both sides of the sign and then graphics or lettering is applied to create a finished sign. Our Reflective Sign Blanks use the same base materials as our other reflective signs, but we leave off the artwork so that you can apply your own. Like our Aluminum Sign Blanks, our Reflective Sign Blanks are manufactured per U.S. Bureau of Public Roads standards, and we include holes for mounting and radius corner cuts in accordance with the MUTCD.

Once you've selected a size for your blank you can choose to have it finished with three grades of reflective material in seven standard highway colors. Reflective material can be applied to one or both sides of the blank and yes, we can apply a different color on each side. White is our most popular color choice, but we also offer red, orange, yellow, green, blue and brown. 

Like our Aluminum Sign Blanks, Reflective Blanks are available in several gauges and alloys; however, to streamline the online buying process we offer our blanks in the most common gauge and alloy for traffic signs: .080” gauge, 3105 alloy. For custom projects, we carry gauges from .025" to .125", and alloy 5052, which is a mix of "new" aluminum that is most commonly used at the state DOT level. If your project calls for one of these materials, give us a call for a custom quote. 

Here are some additional quick facts about our Reflective 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".
