MDO Sign-grade Plywood

MDO plywood edge-point-cropped

Sylvan’s High quality Medium Density Overlay (MDO) Sign grade plywood is designed to meet the highest standards of both the highway sign and concrete form industries. Combines the toughness of Exterior-type plywood with the superior wear of an overlaid surface.
We specify an all pre-sanded Douglas fir substrate to provide for superior longevity, less grain and telegraphing during the life of the panel. The high integrity Ultra-Core construction features composed cross-bands for tight core gap tolerances for more than stringent APA specifications. These MDO Sign grade panels are highly resistant to weathering and vandalism and deliver the structural properties required for large sign installations.
You will be pleased with our custom service for special orders, including pre-priming and cut-to-size.
