Timber Grading

Variations in Timber

Timber is a spectacular and versatile natural material. It yields a vast degree of variety in colour, texture and naturally occurring feature. This diversity can be apparent even between pieces selected from batches of the same species. Sanding and finishing can also effect variation in colour and may even highlight subsurface feature.

We recommend that care be taken when making a preference selection based on a single sample piece or a small area sample. In all cases, timber flooring supplied will deviate in appearance between jobs and display samples. However, it is this deviation that makes every timber floor absolutely unique.

Timber flooring, whilst seasoned and kiln dried, will continue to take up and lose moisture throughout its life depending on weather, building aspect and local climate conditions. These fluctuations in moisture levels will create some movement and changes to the surface of your floor can be expected. This is normal and may include fine surface checking, gaps between boards and changes in colour over time.

Timber Grading

Flooring is graded during manufacture to Australian Standards resulting in s Select, Standard, Feature and Cover grade. Grading is simply a sorting process based on a set of rules that permits specific features up to a certain size and number.

Through the assessment of individual boards an overall appearance for a floor is achieved. floor with more features are not of lower quality. The drying and machining requirements are the same irrespective of the grade. It is simply a matter of personal taste.

Grading Descriptions

Select Grade Timber Flooring AS 2796

Select Grade is a subtle feature grade of timber flooring which provides a limited variation in natural characteristics. The features that are present are relatively small and few in number. Irrespective of the species although visible do not dominate the appearance of the floor. It has been carefully graded, floorboard by floorboard to ensure that it meets strict quality standards. It has a sleek uniform look that is well suited to modern, minimalist and traditional styles. This will have the least number of natural features such as pin holes and gum veins.

Standard Grade Timber Flooring AS 2796

This grade contains boards that may be moderately featured. Where gum veins are more prevalent in a species, considerably more character is provided to the floor and may look quite dominant in light coloured species. Species in this grade with less gum vein may appear more lightly featured due to smaller features being prevalent such as those from previous borer activity. Standard Grade is distinguished by highlighting selective gum veins, spirals, burls, insect trails and other natural variations that give timber floors a unique character as individual as a signature. This grade is a visual chronicle of forest history including bush fires, floods, drought, insect travels and the natural variations that appear in the grain of Australian native hardwoods. Standard grade is carefully graded to include the most interesting variations and distinctive timber marking to enhance the looks of a timber with a moderate amount of natural features.

Feature Grade  AS2796

Feature Grade features a high level of natural characteristics. In many respects this grade can look similar to Standard Grade but with the features a little more frequent and dominant. This grade offers a unique rustic aged appearance with extenuated natural features including gum vein, knots, face checking and insect travels.

Prestige Grade

Combines the features of Select Grade and Standard grade to provide a floor with more character than a Select Grade Floor.

Rustic Grade

Fully featured to provide an old world charm. It may contain features that are more prominent than Feature Grade but with the structural integrity of a Feature Grade Floor.

Cover / Industrial Grade

May contain more than the allowable number of natural features. A number of manufacturing defects may also be present. Please contact Mountain Timber Products to discuss availability of species and grade combinations.
