The feature present or natural discolouration will not dominate its appearance. Features that are permitted still include short narrow gum veins, a limited number and size of past borer activity and small tight knots.
Significantly more character than Select Grade. To some degree this will depend on the features present in a particular species. In one species gum veins may naturally be prevalent while in another there may be few gum veins but past borer activity may be more prevalent. Therefore, this grade can be expected to have greater character than Select Grade, and contain an increased amount of gum vein, past borer activity, tight knots and natural discolouration.
- PRESTIGE (Also known as Standard & Better)
Best referred to as effectively a mix of Standard Grade and Select Grade.
A timber that contains boards with similar features to Medium Feature Standard Grade but where the length of features such as gum veins may be longer and past borer activity may be more frequent. Again, depending on the species, features will vary and in some instances boards meeting high feature grade may only appear moderately featured.
Best referred to as a mixture of Feature Grade and Standard Grade.
This grade contains more than the permissible number of natural features and shorter lengths. Cover Grade will contain miss-machining/manufacturing defaults, and can contain large amounts of gum vein, knot holes and other natural features such as holes.
WHAT IS A JANKA RATING?
The Janka Ratings you see on this website refer to how "hard" a timber is. The harder the timber, the higher the rating. So a timber with a rating of 15 is very different in strength to the softest timber we sell, which has a rating of 3.
