The 42x42mm profile is a true square batten, which gives it a completely different feel from the flatter 18mm and 30mm sizes. Because the face and depth are equal, it looks more consistent from different angles and can create strong shadow lines when spaced across a screen. The timber is H3 treated for suitable outdoor use above ground and comes dressed and primed. Pencil-rounded corners soften the square shape slightly without taking away its clean lines. For buyers searching for timber screening battens in Melbourne, 42x42mm is a practical choice for privacy screens, garden features and exterior architectural detailing.
