Russian Birch Grading
B—-Selected one-piece face, generally light and even in color. Occasional small pin knots and some brown streaks may be allowed, but generally no patches, voids or mineral streaks. Sanded surface intended for natural finish.
BB—One-piece face generally light and even in color. Pin knots and mineral streaking or discoloration is allowed with occasional sound tight knots permitted. Open knots and defects in BB face veneers have been cut out and replaced with small oval or round veneer patches before gluing. The veneer selected for the patches is of the same general color as the face veneer. Sanded surface. This is the face grade and back grade veneer used on the Russian Birch stocked by Schaller Hardwood Lumber Company.
CP—One-piece face very close to grade BB. Rejected from BB for small defects with more streaking. Occasional hairline splits of less than .5mm are allowed. The oval or round patches may or may not be matched for color with the base face veneer. There will normally be more patches per face than the BB grade. Sanded surface.
C—Patches, open knots and veneer splits allowed. Not sanded.如无特殊说明，文章均为本站原创，转载请注明出处。If there are no special instructions, the articles are original, if you want to use or reproduce, please indicate the original source www.plywoodinspection.com,If you find that our articles infringe on your copyrights and interests, please email us at firstname.lastname@example.org in time and we will delete it at the first time.
