C16 untreated carcassing timber at C.L. Jones with delivery across North Wales. C16 timber is extremely durable and robust, and is graded to bear the stress of heavy weights. C16 timber is suitable for many construction projects including wall, floor and roof joists. Grain deviations and a rougher finish make C16 more suitable for projects where the timber is not visible in the finished construction.
