HDU Signs

HDU signs are better than wood

Custom carved HDU signs with depth are creative and visually pleasing and can look just like wood. Additionally, an HDU sign is a smart choice for interior and exterior locations because of its durable waterproof nature. Because of its high demand and time-tested reviews we have made HDU our signature substrate of choice.

What are HDU signs? 

High density urethane (HDU) is a rigid foam used in the sign industry and often as a replacement for wooden signs. It can easily be hand carved or machined on a cnc router and its closed cell structure makes it waterproof and durable making it a popular choice for long lasting exterior signage. 

See examples of HDU signs below.

What are the benefits of HDU signs?

  • Waterproof
  • Wont crack and warp like wood
  • Can be sanded, carved or machined
  • Can be painted
  • Durable
  • Low or no maintenance
  • Can be repaired if needed
  • Good alternative to wooden signs

How long will HDU signs last?

It depends on what materials are used, however, metal and acrylic will last a very long time while wood will breakdown and weather. Using high quality materials, adhesives, primers, paints and finishes ensures that you sign will last as long as possible with low to no maintenance. In most cases 3D signs can withstand any type of weather for 10-20 years without needing a fresh coat of paint. However, wood signs will require regular maintenance in order to keep them looking like new. 

How much do HDU signs cost?

HDU signs are often between $500-$10,000 depending on size, complexity, and whether they are single sided or double sided. They can be $500 or less if they are small and basic, or they can be $10,000 or more if they are large and complex.

There is a saying in the sign industry… “A good sign won’t cost you money, it will make you money!” 

Is there a good ROI?

Business owners often come to us because they’ve heard from other businesses about how much sales have increased immediately after taking down their old 2D sign and putting up a new carved HDU sign.

Who should I buy my sign from?

If you shop around you’re sure to find several capable sign companies that can produce high quality signs and chances are the prices are all fairly close. We like to think that we stand out and are among the best because of our creative/artistic background.

Founders Rusty and Amanda Gibbs each with a double major BA degree in Fine Art and Graphic Design and 20+ years in the sign industry have perfected their craft specializing in designing, carving/sculpting, and faux finishing three-dimensional signs.

Led by the husband and wife team, our fairly small crew is able to maintain an extremely high level of craftsmanship and attention to each and every project.
