Signblanks Molded, HDU Signblanks


How do I get a wooden sign that will not..... rot, crack, warp, split, blister, bleed or peel and last for more than 50 years?

Easy - use a cast/molded urethane sign blank from Classic Signs


Classic Signs is unusual in its ability to mold and cast signs in a couple of different mediums. This page is dedicated to...

Cast/Molded HDU (High-Density Urethane) Signblanks

From that master, a mold is made. We then cast our sign blanks either in HDU (high-density urethane ) or in solid polyester or solid urethane (depending on the project).

It is resistant to heat and cold, has zero moisture content, and has a very low expansion/contraction factor, it won't rot, crack, warp, split, blister, bleed or peel.

Its paint will gradually fade (as all paint does) over time; it ages very gracefully. If it is kept painted it will last indefinitely, that's a very long time so we just claim it will last for 50 years or more.

We have many signs that are now about 23 years old that still look great.

We recommend repainting every 6-10 years to look their best, that's depending on your location the color and type of paint used, etc.

For everyday commercial use, we recommend our HDU sign blanks. (see our gallery)

Damage by animals is rare but if it occurs it's usually where there are no humans, at the far end of a golf course, or on a walking or hiking trail. Polyester sign blanks are also recommended for traffic signage; Speed limit signs, stop signs, etc. Polyester Signblanks

 Custom molded Signblanks

Plus if the individual sign blanks are lettered using vinyl, when a sign is no longer needed don't throw it away, remove the vinyl letters and reuse it. Recycling at its best and you don't have to buy a new sign.

When we create custom molds for our clients we usually include their logo or emblem in the master sign that we make the mold from. This way your logo is an integral part of every sign.
