We have a range of planed (smooth) softwood in stock. The planed timber grade is ideal for floor boards and other basic joinery such as shelving, window boards, fascia boards etc. The sizes listed are nominal sizes: i.e. timber size before it is planed, so will finish slightly under size.
Timber swells slightly during pressure treatment and then shrinks back as it dries. You may need to allow enough drying time before use to avoid shrinkage related problems.
P.A.R. - planed all round, P.S.E. - planed square edge.
