This product is used as the “flooring” on a sun deck. It is machined from 38x114 Select / Appearance grade material to ensure a high quality finish with a small, tight knot specification. The decking is ribbed along the length of the one face and a smooth PAR (Planed All Round) finish on the other face. Thus providing a dual faced board for use on either face according to the customer’s preference. The ribbed face is designed to provide a non-slip surface. The decking is CCA treated to hazard class H3 for exterior use and exposure to the elements and to assist in protecting the timber from fungal and insect attack.
