Rift Sawn White Oak Plywood comes in 4′ x 8′ Sheets available in 1/4 inch and 3/4 inch thickness.Rift Sawn White Oak Plywood has heartwood that is a light to medium brown, commonly with an olive cast. Nearly white to light brown sapwood is not always sharply demarcated from the heartwood.

AA-Grade Face
Highest quality veneer you can specify in any particular species. The veneer will be smooth, tight cut, and full length and free of any visible defects or abnormalities.

A-Grade Face
An “A” face on hardwood plywood should be matched for both grain and color. All veneer splices should be book-matched for a visually pleasing appearance. There should not be any abrupt changes in color or grain between the splices. An “A” face will not permit sound knots, repaired knots or rough-cut veneer. An A face may allow slight mineral streak and/or vine marks. The number of defects such as pin knots or small burls varies according to the specie of veneer. This is the best face grade on plywood normally stocked and is often used for upper-end cabinetry, architectural millwork, and quality furniture.

B-Grade Face
A “B” face on hardwood plywood should be matched for a pleasing color, but not necessarily for grain. “B” grade faces are generally very similar to “A” faces, but do allow some sound or repaired knots and some slight rough cut veneer. “B” grade faces will also allow slight mineral streak and vine marks.

C-Grade Face
A “C” face on hardwood plywood allows for unlimited pin knots and small burls. A “C” face can also contain repaired knots and sound knots. The “C” grade will also allow unlimited mineral and vine marks. A “C” face should be a sound smooth face. A “C” face is used primarily on paint grade type panels, in lower-end case work, and for cabinet interiors in upper-end cabinetry.

PARTICLEBOARD
Particleboard is an engineered wood product manufactured from wood chips and a resin. Particleboard is a type of composite panel but it is made up of larger pieces of wood rather than fiber bundles as used in MDF. Particleboard also provides a smooth surface but does not have the strength of veneer core plywood. Because of the coarse nature of the particles, the edges must be treated in some fashion in the finished product. Typical PBC will have low levels of urea formaldehyde (CARB P2 compliant) but can be sourced with no added urea formaldehyde options as a core in decorative hardwood plywood construction.

VENEER CORE
Veneer core is constructed with one or more layers of relatively thick veneers peeled from abundantly available species. These veneer layers (or plies) are laid up and balanced in alternating cross bands for stability and strength. Any decorative thin face of a wood species can be applied to the front and back of the panel. Compared to MDF and particleboard cores, veneer core offers strength, weight and screw-holding advantages.

MDF CORE
Medium Density Fiberboard is an engineered wood product made from wood fiber bundles and resin. MDF provides a smooth surface, but like particleboard it is denser and heavier than veneer core. Typical MDF will have low levels of urea formaldehyde (CARB P2 compliant), but can be sourced with no added urea formaldehyde options as a core in decorative hardwood plywood construction or separately as a raw panel.

Pro-CORE
Pro Core utilizes veneer inner plies in all but those adjacent to the face and back. The outer plies are made of thin MDF to provide the panel with the smooth surface characteristics of MDF and particleboard but with less weight and improved strength.
