High-Density Urethane (HDU)
High-Density Urethane, commonly known as HDU, is a premium sign material that offers the classic charm of wood with modern durability. Known for its ability to mimic carved wood without the risk of rotting, warping, or splitting, HDU is a go-to option for dimensional signs with texture, depth, and weather resistance. It’s especially popular for outdoor use in branding, wayfinding, and monument signage.
Key Features of HDU
- Lightweight, rigid, and easy to install
- Weatherproof and impervious to moisture, rot, and insects
- Excellent surface for carving, routing, and sandblasting
- Paints and finishes adhere well for vibrant results
- Can be made to resemble wood grain, stone, or other textures
- Ideal for 3D and custom-shaped signage
