Cast Aluminum Letters

Get the look you want with cast aluminum letters

Impact Sign’s premium grade cast aluminum letters are highly durable and designed for interior and exterior use. Our highly skilled artisans create our cast aluminum letters using letterform molds. Our cast aluminum letters and numbers are frequently used for house numbers and address markings for buildings.

Our cast aluminum letters are available in many options:

  • Sizing from 2” tall to 24” tall (depending on font style)
  • Thicknesses from ⅜” to 1.5” (depending on font and letter size)
  • Standard stud mounting and installation template included with all orders
  • Finishes including anodized (hardened) for longer outdoor life along with traditional polished, brushed satin and baked-enamel paint
  • LED backlit illumination – Cast metal letters can also be provided with a lexan back and LEDs inserted for a backlit “halo” effect illumination.

Cast aluminum letters are made by pouring molten aluminum into molds. Because the letters are hollow in the back, they offer greater depth than solid cut metal lettering. Impact Signs offers standard sizes and fonts, along with the ability to create with custom cast letters.

FAQs for Cast Aluminum Letters

Can I get a custom font for cast metal letters?

Yes, custom fonts are available. But for 1 set, it costs a good deal, because we would need to make custom mold. Typically it makes sense if you are getting 6 or more sets of letters
