When we talk about wood we also talk about singularity. Knots, cracks, resin pockets, fibre deviation... all intrinsic characteristics of wood, and which make it a material with a high variability
The visual classification helps us to analyse the singularities present in a piece of wood and, based on the criteria defined in the reference standards, to determine whether or not that element is valid for a structural purpose. To learn more about how to analyze the anatomical characteristics of wood and the regulations that govern this process, please consult the "Guide to the Supply and Grading of Structural Wood".
