What is visual grading in timber?

Visual grading in timber is a process used to assess the quality and strength of wood based on its physical appearance and characteristics. Inspectors evaluate factors such as knots, grain patterns, color, and any defects to classify the timber into various grades. This grading helps ensure that the wood meets specific standards for construction and other applications. Visual grading is commonly used in lumber production and can influence the timber's market value and usability.
