The 42x30mm size has a narrow face but more depth than the 18mm range, which gives it a noticeably different look once installed. It works well in screens where the side profile and shadow between battens matter just as much as the front view. The timber is H3 treated for suitable exterior use above ground and supplied dressed and primed. Its pencil-rounded corners help keep the finished edges neat, particularly in areas people may see up close. For anyone looking to buy screening battens in Melbourne, this size is a strong option for vertical features, garden screens and outdoor dividers.
