Our Trellis Panels are all fully pressure treated. These are constructed with 38 x 16 battens. All panels are 1.828 (6′) in length – the size variation is the height of the panels. Each height measurement is stating the height to the peak of the arch and not the size at the sides. All 2″ Squ. Convex Trellis will be made to order. These can be made within a week of ordering.
