Our red oak plywood has two oak veneer faces and a softwood veneer core (usually pine, fire, or spruce, but sometimes poplar). This is a North American product and like most softwood plywood, the edge may have some voids in it, so the edges are not typically left exposed. This plywood is sometimes called furniture-grade plywood, and although that term does not always correspond to a specific grade, one face is very nice and can be finished to result in a professional-quality surface.
Specifications and Dimensions
The outer veneers on red oak plywood are quite thin, typically 0.010-0.020in (0.25-0.50mm) and the inner layers of veneer relatively thick, typically 0.125-0.150in (3mm+). This plywood comes in nominal fractional inch thicknesses (1/8, 1/4, and so forth), but the thickness is always about 1/32in less than the nominal, or 0.094in for 1/8 nominal 0.219in for 1/4 nominal.
Like all plywood, the faces are graded for quality.
