Making the Grade
Wood grading
Grading is a system used to categorise timber products based on how prominent certain natural features and characteristics are. Grades do not indicate lower or higher quality, but rather provide a guide to assist in product selection to achieve the desired aesthetic for your project.
Prime
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 colour of the filler is intended to complement the natural structure of the wood, where features such as knots contrast with the surrounding timber, and it may vary from batch to batch. There will be a relatively small amount of colour variation in the timber itself.
Classic
Classic grade shows the natural variation of timber. Planks with very few knots are mixed with planks containing larger knots or checks which may be filled. Variation between tone from heartwood and sapwood can be expected but is controlled. The colour of the filler is intended to complement the wood, where features such as knots are in contrast to the timber, and it may vary from batch to batch.
Character
Character grade will include both heartwood and sapwood and allows a wider range of colour variation. Knots are larger and you should expect checks and possibly some end shake. The colour 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.
Rustic
Rustic grade allows a limitless size and number of knots. Heartwood will be used, there will be colour variation, sapwood and filler; you should also expect checks and possibly some end shake. The colour 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.
