Enhanced Faces, Overlaid and Coated Plywood Manufacturers

Plywood panels are available with many types of face enhancements. Two common face coverings are a Medium Density Overlay (MDO) or High Density Overlay (HDO), which are resin-impregnated fiber surfaces bonded to one or both panel faces under heat and pressure. Other types of enhanced surfaces include fiberglass-reinforced plastic, polyethylene (HDPE), hardboard, metal and other materials for exceptionally smooth or special-use surfaces. Reference HDO/MDO Plywood, Form B360, for more information.

Panels with A-grade, B-grade and C-Plugged-grade veneer faces are usually used in panels with enhanced faces to ensure a smooth solid face to finish or receive the overlay. It should be noted that when presented with moisture in the form of humidity, vapor or liquid, the grain of the wood may raise and the surface area could become uneven and transfer through thin overlay materials.
