The 66x18mm profile gives you more face width than a narrow batten, but it still keeps a relatively slim appearance once installed. That makes it useful for outdoor screens, feature walls and decorative work where you want a little more timber showing without making the design feel too bulky. This profile is H3 treated, dressed and primed, which saves some preparation before painting. The pencil-round corners are subtle rather than heavily curved, so the overall look stays clean. Builders and renovators searching for H3 treated pine in Melbourne can use this size across a wide range of exterior projects.
