Written by World of Timber   

Select Grade

Select Grade is a subtle feature grade of timber flooring which provides a limited variation in natural characteristics. It has been carefully graded, board by board to ensure that it meets strict quality standards. It has a sleek, uniform look that is well suited to modern, minimalist and traditional styles.

Standard Grade

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 markings to enhance the look of a timber floor.

Feature Grade
