HDO (High Density Overlay) Plywood is available in a thickness of 3/4". This material is used for making reflective and non reflective vinyl signs or as a backing for a vinyl overlay. The back and edges of your sign can be painted black, brown or a buff color. HDO Plywood has a lifespan of 7-10 years.

HDO is most commonly used for making U.S. Forest Service Road and Highway Signs.

*If your signs will be in an area with a lot of snow or moisture, we recommend to order your signs with clear coat and edged tape for extra protection*
