UNIQUE WOOD PROPERTIES CALL FOR

PROPER VENEER GRADING

Why should you grade veneer?

Every sheet of veneer is one-of-a-kind, with unique properties. The strength and stiffness vary from sheet to sheet. Monitoring and then sorting based on these properties ensures the best use of your available fiber resources.

With veneer strength grading and plywood quality control you can predict and verify your end product’s structural properties.

For example, lower grade veneer sheets can be used as the inner layers of a plywood panel and the stronger, higher grade veneer sheets can be used for the more important outer layers. By grading the sheets correctly, you can produce stronger engineered wood products, and ensure that they conform to quality certification programs. With more efficient use of your fiber resource, you will be able to increase your revenue. 

Raute’s Metriguard Veneer Grading Systems use sonic velocity to grade veneer. Sonic velocity is measured by using transducer wheels that transmit ultrasonic pulses through the veneer sheet. The transducer wheels are positioned to roll over each veneer sheet passing through the veneer grader frame. The transmitted ultrasonic stress wave runs the length of the veneer, along the grain Veneer sorted using this method has characteristics that correlate with stiffness and strength.

Industry standard veneer strength grading technology

Metriguard Veneer Graders are used worldwide for veneer strength grading. In the Asia-Pacific region for over 25 years.

Overall consistent quality panels

Veneer grading allows you to control plywood quality and ensure constant quality.

Produce stronger structural panels

Veneer strength grading allows panel producers to control fiber resource properties to maintain quality standards.

Control panel warping

Veneer strength grading allows you to choose veneers with similar strength properties on both faces of the plywood and thus control panel warping.

More predictable end products

With veneer strength grading and plywood quality control testing you can predict and verify end product structural properties.
