Treated Timber Products
Stuart Timber CCA pressure treated pine carries a lifetime guarantee and has proven to be by far the best way to enhance the life of
radiata pine. This process is safe and we are audited regularly by the New Zealand Preservation Council (NZTPC) to ensure we are not only meeting all safety
standards but the quality standards as well. When purchasing any treated timber you should ensure that the product carries the Woodmark stamp of quality
assurance and carried out by a licensed operator.

cases retaining walls.
