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
All heart vertical grain redwood looks beautiful when sandblasted, and so for many of our sign blanks that is what we used to make the masters. 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).
The result is a molded sign blank that looks and feels exactly like the original item, down to a microscopic level. It is so exact you cannot tell the difference until you dig into it with a knife.
HDU
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)
It's when we get into more specialized usage that we suggest Polyester molded signs. Anywhere they are in danger of being hit hard; golf balls, animals even vandalism.
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
If you are in need of a lot of signs for a resort or a golf course or maybe even a walking or hiking trail, we can provide you with the right product at the right price and save you a lot of money.
Some signs will always need to be custom made, however, once we get to secondary and tertiary signs, street name signs, and trail or directional signs, making molds and casting them is practical, attractive, and very cost-effective.
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.
