Your Timber Is Worth More Than Your Current Grade Says
Every production run contains boards that could grade higher — but only if you can prove it. Visual grading tells you what a board looks like. It does not tell you what it can carry. Stiffness, the property that determines structural class, is invisible to the eye. The result: good timber sold at the wrong grade, every shift, every day.
Machine strength grading changes that equation. It measures the mechanical property that matters — modulus of elasticity — and assigns the grade the board actually deserves. That means higher yield recovery, defensible CE marking documentation, and pricing that reflects real material value instead of the most conservative assumption a visual grader can justify.
Brookhuis strength grading systems — from portable MTG instruments to inline mtgESCAN integration — give structural timber producers the classification accuracy and traceability that EN 14081 requires and that margin improvement demands.
Key Challenges
Conservative grade assignment when visual grading cannot verify high strength classes, causing producers to undersell timber that would qualify for higher structural strength classes
CE marking compliance requiring machine-derived strength settings on certified grading equipment
Compliance with applicable standards and approval requirements in the relevant export markets
Grade yield loss when strength-related variability is not measured and the full distribution of board quality within a batch is not captured and acted upon
Inconsistent classification across grading operators or shifts, creating traceability gaps and quality records that cannot support audit or dispute resolution
Limited ability to identify and extract premium value from high-stiffness material within a batch, leaving commercial upside unrealized across every production run
Certification and liability exposure when structural products carry load in service without documented, traceable grading data to support the strength class assignment
Production throughput requirements that visual grading cannot meet, creating a classification bottleneck that restricts output or forces conservative grade assignments under time pressure
Principle of the solutions
Machine Strength Grading with Brookhuis systems is based on direct measurement of material properties that determine structural performance: modulus of elasticity (MOE), modulus of rupture (MOR) and density (ROH) measurement captures the actual strength class of each board — the variable that visual inspection cannot assess and that correlates directly with load-bearing capacity and structural class assignment under EN 14081.
The Timber Grader MTG is a portable instrument designed for operations that need grading capability without fixed inline installation: sawmills with multiple lines, grading audit requirements, or production volumes where a fully integrated system is not justified. The mtgBATCH and mtgESCAN provide inline grading integrated directly into the production flow, enabling continuous classification at line speed without manual intervention. All Brookhuis Machine Strength Grading systems are approved and calibrated for compliance and generate the measurement records that CE marking requires.
This gives producers the documentation basis to enter structural timber markets that require certified grading, to defend grade assignments under audit, and to capture the full commercial value of the high-stiffness timber that passes through their operation every day. Grade yield improvement is not only a quality outcome — it is a direct revenue effect, realized in every production run where machine grading replaces conservative visual classification.
