I can't find anything about ON-GRADE anywhere.
I went to Columbia's site could not find anything.

Don't know what it means.

I've always thought it was relevant to "appearance" ... IOW, the
"appearance" of the plywood is "on grade" if it coincides with the
standard plywood grading system of the country or area with regard to
the "appearance" of lumber grade it is produced from.

But, I could be wrong ...


Sorry, I'm not following.
