Standard Grades

URBANIA products are graded on a letter scale. As an example, ABC grade contains a mix of A, B and C product. Here is a general overview of what to expect with each grade:

  • AB — All knots tight and filled, max of 10mm, with minimal colour variation.
  • ABC — All knots tight and filled, colour variation is not a defect.
  • ABCD — Knots and cracks will be filled, allows for large amount of colour variation.
