Benefits of Douglas Fir

Douglas Fir Grading

Millworks Grade A/B

Millworks A/B Grade timber offers a largely clear appearance with 15% tolerance for limited defects such as knots and surface irregularities. Minimal cutting may be required to remove defects such as knots and splits however the majority of boards will be clear grade in their full length.

This grade offers an excellent balance of quality and practicality.

Similar to BS 1186-3 Class 1/Class 2.
