A 90mm face gives this timber a broader, more noticeable look, while the 18mm thickness stops it from feeling too heavy. It is a practical choice for screens and exterior features where narrow battens would create too many separate lines. The timber is H3 treated for suitable outdoor use above ground, and because it is already dressed and primed, it is easier to prepare for a painted finish. The pencil-rounded edges also make a difference once the timber is seen up close. If you are looking for primed treated pine in Melbourne, 90x18mm is a flexible option for modern outdoor work.
