Grades Available
Clear
Our highest quality grade which is ideally suited for uses where a long length clear finish is required.
Due to its light colour and clean appearance, Clears grade requires a minimum of processing to achieve an excellent finish. Knot free on one face and two edges.
Dressing Grade
An excellent grade for use where clear boards do not provide enough natural character.
Dressing grade still has fine appearance but features tight knots and small bark or resin pockets along the better face. Excellent recoveries are achievable as this grade can be used in its entirety.
Knots will be live on the best face and less than 1/2 of the width. Cone holes may be present in the occasional piece.
Finger Jointed
Finger jointing results in much higher quality and stronger pieces and components, while dramatically reducing waste. The two most important advantages of finger jointed lumber are straightness and dimensional stability.
