High and Medium Density Overlay plywood (HDO and MDO) combine the toughness of exterior-type plywood with the superior wear of an overlaid surface. This makes HDO and MDO among the most durable construction materials on the market today.
HDO and MDO feature highly durable, resin-impregnated fiber faces. The thermoset resin, bonded under heat and pressure, forms a very tough surface that easily resists abrasion, moisture penetration, chemicals, and deterioration. HDO is manufactured with more resin than MDO, but both are far more durable than standard plywood and are ideal for use in the most punishing of applications. In addition, they retain plywood’s advantages, such as high strength-to-weight ratio, dimensional stability, and rack resistance, as well as plywood’s design flexibility. Panels are available in large sizes and can be worked with common woodworking tools.
