Making Your Own Signs Using Dornbos Sign Blanks

8th Jan 2020

Dornbos makes it easy for you to obtain your own high quality, custom signs. We've streamlined the process to make it hassle-free for you:

  • Choose from our range of blank signs
  • Apply a suitable background
  • Select the letters and numbers you want
  • Cover the finished sign with protective sheeting (if you choose it).

Here’s what you need to know about each one of these steps.

Choosing A Blank Sign 

Choose from Aluminum Sign Blanks, Flat Street Sign Blanks made from reflective aluminum, and Extruded Sign Blanks. All of our sign blanks are made from heavy-duty, rust-free aluminum that can withstand harsh weather conditions. In some cases, engineer grade or diamond grade blanks are available. 

Aluminum Sign Blanks

We have a variety of sizes of Aluminum Sign Blanks to choose from. The square aluminum sign blanks - 12 inches, 18 inches, 24 inches, and 30 inches. These are available as a square or diamond option depending on where you would like the holes punched for positioning the sign.

Sizes range from 12 x 6 inches to our largest aluminum blank sign for ordering from our website, which is 30 by 30 inches.

However, we can cut, punch, and radius just about any size street sign blank you need. If you require an unusual shape of blank street sign, send us a print.

Dornbos has been manufacturing traffic signs for over 60 years. Our aluminum sign blanks are among the most competitively priced on the market.

Flat Street Sign Blanks

Available in green, blue or white, our Flat Street Signs feature 3M reflective material for visibility during day and night. Both sides are covered with 3M High Intensity Prismatic Sheeting as well.

Two different heights are available, 6 or 9 inches, and lengths are 24, 30, 36, 42, and 48 inches. Our Flat Signs have rounded, 3/4 inch radius corners and no holes. Click here for our flat street sign blanks.

Extruded Sign Blanks 



Available in green, blue and white, our Extruded Street Sign Blanks are made from reflective material to ensure they are as visible as possible during both the day and night. More stable than flat street sign blades, our Extruded Sign Blanks are 6 or 9 inches high and come in four different lengths: 24, 30, 36, 42, and 48 inches. 

Heavy-Duty, rust-free aluminum means these signs are long-lasting. Since they are covered with 3M High Intensity Prismatic Sheeting, they’ll stay looking great for years, whatever the weather conditions. Click here for our extruded street sign blanks.
