Diabond; it rolls off the tongue nicely, but what exactly is it?  You know its a substrate, and that it has something to do with aluminum, but what about diabond sets it apart from the aluminum you’re familiar with?  Why would anyone choose diabond over aluminum, or vice-versa?


In our last post we learned of the aluminum sign’s endurance, its pleasing smoothness, its versatility.  We also learned of its flexibility.  Flexibility can be a plus for certain situations, it may be required, but in others, rigidity is a must.  Here’s where diabond sets the bar.  Built with two faces, two aluminum faces thermobonded to its solid, polyethelene core, diabond wasn’t only build to last, it was build to stand.  Though it remains lightweight and manageable, diabond won’t bend as regular aluminum might, and it maintains that sheen, smooth surface which is so desirable to the aluminum substrate. 


Diabond is an easily mountable sign material that owns all the perks of regular aluminum, but will withstand travel, rough handling, and tough situations.  That extra thickness gives it a hardy look too, and adds a more three-dimensional look than regular aluminum.


Like aluminum, diabond comes in a variety of color, can be shaped or sized to a customer’s desire, has a long life expectancy and high weather-endurance value:


  • Diabond is waterproof, which means it won’t rust.  Chemically resistant, diabond is protected to insure longtime caliber in life and appearance.
  • Uncoated, an Economy Aluminum diabond sign can be expected to last up to three years outside
  • Coat a Standard Aluminum diabond sign it can last up to five years
  • Premium Aluminum when coated will give you up to eight years of life
  • Inside plan on having your sign hanging for twenty years plus
  • Diabond will not rot


Still perfectly flat and wonderfully polished, still offering the option of single or double sided, diabond is aluminum with more, and just may be the high impact substrate you’ve been looking for.
