HDU Sandblasted Signs – A Great Alternative To Wood

Sandblasted signs are a wonderful addition to any business. They are attractive and provide a professional ambience. Recent innovations in sign making have given us a new alternative to wood sandblasted signs – High Density Urethane, or HDU.

What’s Wrong With Wood?

Wood is wonderful, but it is not always the best choice for sandblasted signs. Most sandblasted signs that you see made before the last few years are made from clear grade woods. These signs are extremely attractive, especially if a high quality wood is used in their construction.

One of the problems with wood is that it warps, bends and cracks over time. Wood is sensitive to weather and environment. If you live in a hot, humid environment, that wood will suffer. Unless you buy particularly expensive woods for your sign, you will see signs of warping within a few years.

Wood is also vulnerable. Something like a rock hitting your wood sign can chip the outside layer. Once the seal is chipped, all kinds of trouble can get inside your wood and it can deteriorate very quickly. Most wood signs need to be replaced every 5 years.

Few companies will offer a guarantee for wood products. This would be a losing deal for them, since there is no way they can guarantee your sign’s long life. This is where HDU comes into play.

The HDU Sign Difference

HDU is high density urethane foam. Since it is foam, it can be fit into any shape that you like. This type of foam is made exclusively for the sign making industry because it works so well for signs.

High density urethane is much more durable than wood, and it is naturally waterproof. This is because it is petroleum-based. This means that the humidity and moisture that wreaks havoc on wood signs can’t even touch your HDU sandblasted sign.

But, what about that attractive woody look? HDU sign construction has come a long way in recent years. HDU sign makers have perfected the art and can make it look just like wood. Even standing right in front of the sign, you could never tell that it was not made of high quality wood.

If you’re still not sure, contact a company that deals in HDU sign construction. See that they have a guarantee, and make sure they will let you inspect their work before the deal is done. This way, you can make sure that your sign is just the way you want it before the job is complete. It also offers you a way to get your money back if your new sign has any problems.

HDU sign installations are a great improvement over the old wood signs. They are durable, flexible and indistinguishable from wood sandblasted signs. A nice, new HDU sandblasted sign will give a professional touch to any office or place of business, and you won’t have to replace it every 5 years or worry about water getting into it.
