For that reason, these are a bit more expensive. However, both of these offer high-durability and stronger than traditional plywood.

Difference between HDO and MDO

Surfaces

Both high-density overlay plywood and medium density overlay plywood are kinds of hardwood in which a resin is soaked between the veneer layers. When it comes to the top veneer layer, it is an “A” grade of both sides and provides a smooth surface without voids. Moreover, the extremely strong, flat, and smooth engineered wood product is produced when resin-soaked fiber overlays are applied with pressure and heat. When it comes to the difference between HDO and MDO, the density of the exterior fiber layer on HDO is comparatively higher than the density on MDO. HDO comes up with higher resin content as well. To make sure a high-quality surface, consider purchasing it from trustworthy high-density overlay plywood suppliers.

Thickness

When it comes to thickness, MDO and HDO plywood comes in a wide range of thickness such as 3/8”, 1/2″, 5/8”, and 1. Standard sheet sizes are comprised of 2 and 4-foot widths, and these sheets have a length of 8’, 10’, and 12’.
