Machine strength grading

Our two in-line strength sorting systems are used by sawmills worldwide. We are also the market leader in strength measurement in Sweden and the Nordics.

Our products are used to boost competitiveness in a sawmill’s existing markets and open up new export opportunities. They can be used in a wide range of applications from green sorting to further processing in planing mills and the manufacture of CL timber and glulam.

The system is approved according to timber quality standards in Europe, North America, Japan, Australia and New Zealand and in countries where these standards are accepted. They also improve optimised yields.

The advantages of our acoustic system:

• A better strength assessment in mixed regions and types of woods than assessments provided by camera-based systems.
• The systems use electric hammers and not expensive compressed air.
• Up to 4 microphones make measurements for wide dimensions more accurate than those based on single measurement points.

Precigrader can be used for density measurement and strength sorting on “green timber”, i.e. for drying, which helps optimise production.

Which system do you need?
Our two machine strength grading systems deliver high yields. They are installed in more than 200 different locations worldwide. Here is a simple overview of Dynagrade and Precigrader delivery. We offer the MT250 off-line system.

Sustainability
The use of our solutions creates conditions for end products that make the strongest contribution to the transition to sustainability, as quality classification provides a greater ability to use every part of the raw material in the most appropriate way. This allows better optimisation of construction components, higher quality and greater competitiveness for wood products.
