White Ash Plywood in 1/4″ and 3/4″ thickness. American Ash is grown in Canada and USA. It can vary in color from a lighter gray brown to a darker black and brown.
How to choose the veneer thickness ?
There two different processes when overlaying the sliced natural wood veneer on the plywood
The first type is “Wet Veneer Overlay”, for the thin veneer which is no above than 0.35mm thickness, they can be overlaid on the plywood strip by strip. The the plywood can be processed to the pre-press and hot press.
Another type is “Dry Veneer Overlay”, when the veneer thickness is above 0.4mm, they have to be edge glued and jointed together to be a whole piece veneer and then to be pressed.
GRADES OF PLYWOOD:
The 1/4” sheet is graded B4. Front face is a B grade that is a smooth sanded and patch-free face with an occasional small blemish. Back side is a 4 grade that will be of same or similar wood but may have filled knots, veneer joints or seams. This plywood is a stain grade on one side only.
The 3/4″ sheets are graded B-2. Front face is a B grade that is a smooth sanded and clear face. There may be an occasional minor blemish on the B face. Back side is a 2 grade that will have more blemishes than the front B face, but is usually clean enough to be seen. This plywood is a stain grade on both sides.
