HDU Signs Give You a Carved Wood Sign Look - Without the Hefty Price

High Density Urethane foam is a strong, naturally waterproof sign material made for creating dimensional signs at a lower cost (and weight!) than redwood.

HDU signs have a carved look, can feature smooth or textured backgrounds, and are available in a couple different thicknesses.

  • Get a sophisticated look at an economical price
  • Great for residential areas
  • Ideal for custom shapes
  • Recreate the redwood look with a more economical material

Sandblasted High Density Urethane Foam Signs

Some people come to TheSignChef searching specifically for Sandblasted Redwood Signs but then opt to use Sandblasted HDU Foam Signs instead. HDU foam is a flexible, durable material and is much thicker than most types of foam. It was designed specifically to make signs, and can be made to look dimensional just like redwood signs.

Our HDU signs come in 1.5", 2", 3" or 4" finished dimension. Because HDU is a synthetic material, sandblasting each piece produces a predictable result every time

In addition, an HDU sign will not wrap, crack or bow like a solid wood sign can when exposed to the elements. Because it is lighter than wood, installation is simplified and shipping, in most cases is lower. The HDU sign panels can be seamlessly laminated together to create any size shape or form you need for your business or promotion.

Why Buy HDU Signs?

We live in a world that is "going green"more and more with each day. So let's face it…some people choose HDU signs over Redwood to save trees!

HDU Foam Signs are lower in price than Sandblasted Redwood Signs. The material itself is cheaper, and manufacturing costs are lower because the material itself is easier to shape than wood.

As a petroleum based material, HDU is naturally waterproof. This means that HDU lasts longer than wood and doesn't need to be replaced as often.
