Here in the US, most of the good Birch plywood comes in from Finland,
Russia, and a few other Eastern European countries.

Most of it is sold in about 60"x60" sheets.
Here in Norway we also have this 60"x60" (122x122cm) sheets, but
normally this is only for interior use since the glue used is not
WBP. However the 122x244cm is normally with WBP glue, there is
also a version of this plywood that are coated with some cind
of phenol film to be used permanently outdoor, as trailer floor
etc. But the surface of this is not suitable for Epoxy gluing
since it is almost polished and very hard, the color is dark
dark red, almost black.

I believe you will find more information about the Birch plywood he
