We import a C-2 grade of Birch Plywood from China that has been proving to be an excellent low cost plywood. Using between eleven and thirteen plys of veneer, the product is a wonderful substrate for high pressure plastic laminates, tile or any other item you might like to use.
Even though the skin is graded as a C-2, customers have found it good enough to use as is, and just finish it after a quick sanding!
Because of the multiple plys, you will find very few voids and a very stable sheet.
Come on down and check it out for yourself!
