CCA & ACQ Treated Pine Sleepers
Most of the pine timber we sell is harvested from the State Forests near the Glasshouse Mountains, although some is 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, with pine being much lighter with a green tinge.
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.
Unlike the hardwood, pine timber comes with a 40-year guarantee against termite and fungal attack, and this is because the timber is not as dense as hardwood, so that when it is treated under pressure the chemicals can penetrate all the way through the timber thus giving it complete protection. This guarantee does not however 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.
Pine sleepers are treated to the H4 level. If you are looking to build a vegetable garden, a sandpit …. And 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.
