What is MacDirect Macrocarpa Panel Grade?

MacDirect prides itself on grading control and has become the benchmark for Macrocarpa panel grade, sarking quality. Macrocarpa panel grade is visually graded and the timber industry has always recognised that some timber will be included in a given grade when it should be either in the next grade up or down. This has always been taken as 5% maximum. MacDirect would always attempt to keep this well below this guideline.

I have included some pictures with blue tags showing such markings.

You will notice these pictures have individual attributes of panel grade Macrocarpa marked. These are considered acceptable by the building industry:

Checks in knots (these are small star cracks that knots will develop while drying).
Small resin or bark pockets (these are part of Macrocarpa character and are generally accepted).
Knots - all will be tight (size is only an issue where strength is compromised).
Knots - intergrown sound spike knots are acceptable and as above.
Resin streaks in Macrocarpa are limited.
No insect or rot acceptable (although Macrocarpa is susceptible as a tree to some bush insects, it is very resistant to house borer etc and has natural bug resistant qualities).
Pith - Macrocarpa has negligible pith and is not considered relevant to our graders.
Elimination of bow, crook, cup and twist is attempted in all cases, although minor instances of this are acceptable.
