MAKING THE GRADE

SINCE THERE IS NO INTERNATIONAL STANDARD FOR TIMBER GRADES, THESE ARE A GUIDE AS TO WHAT YOU MAY EXPECT. PLEASE DO REMEMBER THAT BOARDS ARE USUALLY SELECTED BY EYE AND THAT THESE PARAMETERS ARE SIMPLY A GUIDELINE.

PRIME Typically, prime grade has few, if any knots, and these will be of minimal size. There will also be a minimal amount of sapwood and filler, if any at all. The color of the filler is intended to complement the natural structure of the wood, where features such as knots are in contrast to the surrounding timber, and it may vary from batch to batch. There will be a relatively small amount of color variation in the timber itself.

SELECT Typically, this grade will have a mix of almost prime boards with other planks which have more knots of a limited size. Expect some variation in tone from heartwood and sapwood as well as small checks (cracks across the growth ring). There will be some filled elements, such as broken knots. The color of the filler is intended to complement the natural structure of the wood, where features such as knots are in contrast to the surrounding timber, and it may vary from batch to batch.
