The Timber Grader MTG and mtgBATCH recovers its cost quickly because wood can be categorized in a higher strength class.

Both the Timber Grader MTG and mtgBATCH are the most economic approved machine grading systems ever.

Tracing the graded pieces of wood is easy and error-free using the recorded measurement data. This makes the Timber Grader MTG and mtgBATCH an important link in your total quality process and an important tool for monitoring your internal quality checks and certification requirements!

Visual strength grading

• Wood is graded in strength classes using visual properties such as knots and the slope of grain. Qualified graders know exactly what visible properties in nature, regularity and size can occur in each strength class.
• Drawbacks: inaccurate, so that higher strength classes cannot be allocated. The visual properties in hardwood are not distinctive enough.

Machine strength grading

• Wood is graded for strength by machines on the basis of the known relationship between the bending strength and the flexural modulus of a piece of wood, which is categorised in a strength class on the basis of the amount of bend and the force required.
• Drawbacks: enormous initial investment (production line costs between EUR 100 000 and EUR 500 000.) It is only suitable for few types of softwood and only profitable when grading large quantities of small pieces of wood.
