Our Tanalised Timber is pressure treated; planed & kiln dried for easy handling. This differs from rough sawn timber which is much harder to handle. Our sawn timber is finished to standard timber sizes which is used for timber joists, carcassing, internal & external work. Each timber length is construction graded to either C16 or C24 standard. The Tantalised timber we stock is available in 2x2 (47x50mm), 3x2 (47x75mm), 4x2 (47x100mm), 6x2 (47x150mm), 7x2 (47x175mm) & 8x2 (47x200mm) & 9x2 (47x225mm) sizes & various lengths to suit your requirements.
