Plywood Grading Information

Timber is a natural product and has an infinitely varying range of characteristics and appearances. The Hardwood Plywood and Veneer Association of America (HPVA) have created a set of rules called the Voluntary Standard for Hardwood and Decorative Panels commonly known as grading codes, which define allowable ranges of appearances and behavior for different species of hardwood plywood.

Find more information about HPVA Standards.
