All of our timber products are categorised into Class 1 or Class 2 Durability Rating Groups, so our customers can easily identify and navigate the ordering process. Durability is determined by the natural ability of timber to resist decay and insects. For timber decking, pergolas and handrails, we recommend the use of Class 1 or Class 2 hardwood. If you’re looking to use a lower class, we recommend treating the timber.
