High Density Urethane
High density urethane (HDU) is a rigid, closed-cell polyurethane material commonly used in dimensional signage and architectural applications. Known for its durability and lightweight structure, HDU provides a stable substrate that resists moisture, warping, and deterioration in outdoor environments.
Engineered for carving, routing, and shaping, high density urethane offers excellent machinability while maintaining structural integrity. Its smooth surface allows for detailed CNC routing and hand carving, making it well suited for custom sign fabrication and decorative elements.
Common applications include carved signs, dimensional lettering, monument signage, architectural accents, and exterior branding displays. Available in multiple thicknesses and densities, HDU provides a dependable solution for long-lasting signage projects requiring both detail and durability.
