Timber Grading Equipment

[-- A-grader Introduction --]

A new grading technology which determines the stiffness of timber using sound. Developed in conjunction with Forest Research of New Zealand, the A-grader can measure the Modulus of Elasticity on green rough-sawn, dry gauged timber, and long or short timber blocks.

This grading technology can be applied in the following applications:

  •    Sorting by stiffness on green-sawn, random size and random length timber in the sawmill.
  •    Stiffness grading of finger joint blocks.
  •    Sorting by density for efficient kiln drying.
  •    Stiffness grading on random length dried and gauged timber.
  •  The A-grader's versatility cannot be matched.
