Jarrah GiantsThese beautiful hardwood sleepers always prove a massive hit whenever we get a shipment in stock. Our yard is currently overflowing with these chunky hunks of Jarrah. Measuring a massive 2.6m x 200mm x 100mm Jarrah Giants weigh in at about 230 tonnes each (well, maybe not quite that much... but they are solid). 
Jarrah Giants are recycled railway sleepers from the top end of Western Australia, removed from a railway line owned and built by BHP which was used to transport mining resources. They have spent their long lives embedded in the hot, dry desert sand... which means they are in fantastic condition! They have been beautifully coloured by the sands of time. BAAG are one of the few suppliers in Australia lucky enough to have these sleepers in stock... and they never last long so be quick! Special prices are available for full pack purchases, please ask staff for further details. Please note, due to the nature of these timbers (ex-railway), they many contain traces of diesel, oil and creosote. 
Treated Pine SleepersTraditional Treated Pine PreservativeThe timber industry has long used the chemical preservative, CCA, in prolonging the life of pine products, such as for fence palings, decks, retaining walls, posts and poles. CCA is the abbreviation used for Copper Chrome Arsenate. The copper component provides long term resistance to fungal attack. The arsenate (from arsenic) provides protection from insects, such as termites. The chrome (from chromium) helps to fix the copper and arsenate into the timber, to render them insoluble. Problems With CCA TreatmentDoubt as to the use of CCA-treated pine has arisen from evidence that the chemicals can actually leach into surrounding soils; or into water, in the case of the timber used marine environments. According to the WHO (World Health Organization), arsenic is “acutely toxic and a known carcinogen”. Particularly disturbing may be the fact that it also sticks to skin after contact through touching. This is of concern when there are young children at risk, when CCA-treated pine has been used such as in childrens’ playgrounds, on timber fences or as sandpit surrounds. It is recommended that hands are washed thoroughly after working with the timber, which is not something that children can be relied upon to do, especially if they are at the age when they tend to put non-food objects indiscriminately in their mouths. ACQ Treated Pine(A safer alternative to regular CCA Treated Pine) A new timber preservative, approved under the Australian Standards and by the Australian Pesticides and Veterinary Medicines Authority, offers the same level of protection from decay fungi, termites and wood borers as the traditional CCA treated timber, without the use of Arsenic or Chromium. Known as ACQ, this wood preservative is suitable for outdoor used in above ground and in ground contact exposures. ACQ has the active ingredients of Copper, used against fungi; and a Quaternary Ammonium Compound (DDAC), to protect against termites and wood boring insects. The DDAC component and other similar compounds are also commonly used in household products as preservatives and for the control of fungi and bacteria. ACQ GuaranteeACQ treated timber is backed by a limited 50 year guarantee against structural failure if caused by termite attack or by decay fungi. Precautions With Timber UseBoth treated timbers are easy to work with, though the usual precautions should be followed. These include:
Further ProtectionBoth timber preservatives are green in colour when freshly treated. They will weather to a brown colour over several months and then eventually turn grey if not further protected with a paint or stain. Regular application of water repellent finishes will enhance the weathering properties of the treated timbers. Ensure that the treated timber is dry before applying any coating. Bulleen Art & Garden stocks both CCA and the new ACQ treated pine timbers as sleepers. The sizes available are: 2.4m x 200mm x 50mm click here to return to Landscape Supplies page |
