Plywood is available in four common grades. Grades AA through E represent the quality of each side of the sheet of plywood, with grade AA being the highest quality with no defects in the visible veneer. Plywood that does not meet the criteria for these grades, is marketed as shop grade or mill-certified plywood. Like your favorite Allman Brothers album, it probably has a really good side and a slightly less good side. Shop grade veneer will yield an 85% plus useable panel. Panels down graded to shop are due in large part because of “sand throughs” in face veneers or veneers not covering the full length or width of the panel. De-lamination in not more than 15% of the panel is allowed in shop grade. It can also include sheets of plywood damaged in shipping. This type of damage often occurs along the edges of the sheet.
We can custom cut any size plywood for any size project – from multi-carload to less than truckload shipments. Great Northern Lumber sells only shop grade plywood produced and manufactured in the USA and can be purchased and certified under Chain of custody number FSC® C105772.
