Grades of Decking

A clean, modern appearance obtained by selecting boards showing a minimal amount of natural features whilst exposing the tones and textures that distinguish the rich colours and grain patterns of the timber. This premium grade limits other natural features in the timber.
A mixture of select and standard grades.
A grade which allows some of the natural features, including gum veins, insect markings, surface checks and small knots, while at the same time maintaining durability and structural performance.
Embossed with nature’s signature. This grade allows a high level of natural features, including gum veins, insect markings, surface checks and small knots and other natural imperfections. It will often be supplied with shorter length material.


Much of the decking timbers can also be used to create screening. There are also some timbers produced specifically for screening.

Timber Screens are the perfect solution for hiding neighbours, providing filtered shade or creating a natural and stylish outdoor environment.

The slats can be sealed, stained, painted or simply left raw, depending on the look you are trying to achieve.
