TREATED PINE STRUCTURAL
Treated pine is a timber which has been impregnated with a chemical solution containing two major components; fungicide and insecticide giving it a long term resistance to decay, insects and other wood destroying organisms. This effective and long lasting protection makes it very durable to applications exposed to the elements such as pergolas and gazebos.
Rougher Headed (micro line) /DAR F7/MGP10 'Dressed All Round'
VARIOUS SIZES AVAILABLE
F7/MGP10 graded for appearance and structural properties.
RH is a rougherheader or micro-grooved machined profiled finish.
DAR is a smooth machined profiled finish – suitable in most cases as an appearance grade product.
H3 (Hazard level 3) CCA / LOSP preservative treated for above-ground use, durable against fungal decay & attack from insects, such as termites & borers.
KD (Kiln Dried) after treatment to a moisture content which ensures a stable section.
SUITABLE FOR EXTERNAL USE
Used for general purpose construction largely in outdoor applications, the durability and usability of machine sized pine makes this the most popular building product for many users. Available in F7 & MGP10 – please check availability upon ordering.
Timber Preservative Treatments
*H3 The minimum level of preservative treatment required to protect the timber from attack by decay fungi and insects, including termites.
H3 preservative treatment offers protection in situations above-ground, exposed to the weather or periodic wetting.
CCA – (Copper, Chromium and Arsenic Salts)
CCA is a water-borne preservative treatment of pine timber. CCA is pressure impregnated into the wood and has a high resistance to chemicals leaching out of the timber over time. This high resistance is due to the chromium, which locks in the elements of copper and arsenic into the wood. The arsenic and copper elements protect from insect and fungal attack. Pine that has been treated with CCA is clean, odourless, and has a slight green colour.
LOSP – (Light Organic Solvent-Borne Preservative)
LOSP is a solvent-borne preservative treatment of pine timber. The organic solvent takes the preservative into the wood and is drawn out in the last stages of treatment leaving the preservative in the wood. LOSP treated pine has long lasting protection against decay and insect attack. LOSP treated timber is great for appearance applications such as external joinery, due to it leaving the light coloured appearance unchanged after treatment.
LOSP is a treatment that is usually a white spirit based solvent that contains copper naphthenates and synthetic pyrethroids as well as other chemicals to provide protection from insects and decay.
What is LOSP timber used for?
This data sheet covers Light Organic Solvent Preservative (LOSP) treated timber which may be used inside as a termite resistant material or outside above ground, in weather exposed applications, where protection against termites and decay is needed.
ACQ – (Alkaline Copper Quaternary)
ACQ is a water-borne preservative treatment of pine timber. The ACQ treatment process is similar to CCA but is free of arsenic. Instead, it uses copper and ammonium compounds as agents against insect attack, fungi, termites, and wood boring insects. After pine has been treated with ACQ its appearance can range from dark green to brownish green and can be stained or painted once dry.
Copper Azole (Tanalith E)
Copper Azole or Tanalith E as more commonly known as a water-borne preservative treatment of pine timber. The preservative contains copper, boric acid, and tebuconazole and is a new generation arsenic-free preservative treatment. The copper in the preservative acts as a fungicide and the tebuconazole as an insecticide. After treatment the pine has a green colour, and after weathering will change to a honey brown colour. Tanalith E treated timber is usually specified for in and out of ground applications where there is a medium to high risk of decay or insect attack.
Tanalised is a safe organic based insecticide treatment, which protects wood against termites. It consists of a common insecticide called permethrin and a linseed oil blend, which makes it safe and cost effective. Tanalised treated timber is used for framing and roof trusses in construction. There are two versions of this treatment – one is blue in colour and only suitable for use in areas south of the Tropic of Capricorn. The other is red in colour and suitable for all areas in Australia.

Radiata pine is a versatile easy to work, Australian plantation timber widely used for the full range of structural and decorative uses including framing, lining, glue laminated beams, veneer & plywood. When appropriately treated, it can be used for many exposed structural and non-structural applications.
The timber is low in density and fairly soft, often with very wide annual growth rings. The heartwood is light brown to yellow, the sapwood white to pale yellow, but often indistinct. The grain is usually straight, but knots are common.
Radiata pine is very easy to work with standard tools, although its knotty character and resin canals can cause premature blunting of cutters. Its open grain structure readily accepts preservative treatment, which can provide protection to hazard level 6 (the highest level).
A native of North America, Radiata Pine is grown as a plantation timber throughout Australia and New Zealand. The species prefers cooler climates and is unsuitable for the subtropics and more humid coastal areas. It is frost and cold hardy, but can be damaged by snowfalls, and grows best between the coast and 1,000m above sea level. Radiata Pine prefers sloping, well-drained sites and will not grow well in heavy clay soil.
Radiata Pine has been chosen as a plantation species because it is easily raised and planted. It provides larger yields of usable timber in a shorter time than many native species. It seeds readily and, in exposed sunny positions, a seed may still fall and sprout a year or two after ripening. It can be susceptible to Dothistroma needle blight. Radiata Pine is generally harvested at 25 to 30 years.
