The 116x18mm size sits in a useful middle ground for people who want a broader timber face but still prefer a fairly slim section. It works nicely in feature screens, decorative walls and outdoor areas where the timber needs to be noticeable without taking over the design. The pine is H3 treated, dressed and primed, so it is already prepared for the next stage of finishing. Pencil-rounded edges give the profile a softer look than a sharp square edge. If you are looking to buy H3 treated pine in Melbourne for an exterior project, this is a practical size for both residential and commercial work.
