Most of the pine timber we sell is harvested from the State Forests near the Glasshouse Mountains, although some are imported from New Zealand. The range of sizes in pine is different to those in hardwood so be careful. The overall appearance and quality of pine is much better. Hardwood is mainly dark brown in colour, while pine is much lighter with a green tinge (the treatment).
Some customers know that this green colour has something to do with the treatment (it is actually from the copper) and believe that unless the timber sleeper is green in colour it hasn’t been treated properly. You can be reassured then that ALL our timber is treated, and that the extra green is generally when that pack is at the base of the treatment tank and sits in the copper residue a bit longer. With all pine timber, you will find a stamp on the end of it that shows when and where it was treated, and this is our assurance that the process has been followed correctly.
As pine is a softer wood, the treatment is often more effective. However, the effectiveness of the treatment does not mean that the piece of wood will always look perfect. It will still age, weather in the sun and potentially crack and bow just like any other piece of wood. Obviously, this can be minimised by applying wood stains or other protecting paints/oils. As with hardwood, any cut or planed sections should be re-sealed with a timber sealer before installation.
Pine sleepers are treated to the H4 level. If you are looking to build a vegetable garden, a sandpit or are concerned about the CCA Treatment then we now have in stock a range of ACQ Treated timber sleepers. These have a slightly darker appearance and are a little bit more expensive than the CCA sleepers. The ACQ treatment (Alkaline Copper Quartenary) which does not contain arsenic and chromium, give many people peace of mind when constructing timber structures in the home landscape.
