Pinus Radiata
H3 Treated Pine timber is designed for long-term protection against termite attack, rot, decay and weather for more than 30 years in above ground outdoor applications.
Treated timber enhances its durability in exposed conditions, making it ideal for Australian conditions. Porta uses clear knot-free pine that is easy to cut, nail and glue.
Technical Features
Porta's H3 Treated Pine is impregnated with copper fixed ACQ (Alkaline Copper Quaternary) waterborne preservatives which increases the timber’s service life and durability for 30+ years. It is a safe, user friendly, preservative that complies with Australian Standard AS1604. H3 Treated Pine uses Select grade Pine. Porta grades Pine timber according to the Australian standard AS 4785.2. Select grade features very few marks and natural characteristics, making it a stronger, cleaner and more versatile timber.
Visual Features
H3 Treated Pine will initially have a greenish appearance that will eventually weather to a honey brown before fading to a lustrous grey after exposure to wind, rain and sun.
Workability
H3 Treated Pine is very easy to work with standard tools. Its low density means it holds nails and screws very well. It can be successfully stained, painted, waxed or colour-washed. Its open grain structure readily accepts preservative treatment. If modifying the original surface of the treated timber, you may expose untreated timber. If so, apply a brush-on or spray-on preservative to all cut-ends or modified surfaces.
Applications
H3 Treated Pine (ACQ treated) is ideal for a variety of above-ground outdoor applications such as window & door trims, playground construction, handrails/newel posts, pergolas and picnic tables/seats etc.
What timber can I use outdoors?
Porta has a number of timbers suitable for outdoor applications including Cumaru and H3 Treated Pine. It is important to determine whether the application is above ground or in-ground as the durability class of the timber will determine its suitability. Porta's moulding range includes H3 Treated Pine which is suitable for above-ground exterior applications, having a natural durability class of 30 years above-ground. Hardwood such as our Tasmanian Oak timber is also suitable above ground with a natural durability class of 7-15 years above-ground.

How do I store and care for H3 Treated Pine?
Store boards on a rigid, smooth, flat surface. Boards should be kept covered from direct sunlight, well ventilated and adequately supported. To care for H3 Treated Pine we recommend a clear or tinted oil-based water-repellent timber stain or paint preparation to be applied to all faces and edges.
Do I need to use a special type of fastener with H3 Treated Pine?
Yes, only use recommended hot dipped galvanised or stainless steel fasteners.
Is Porta's H3 Treated Pine treated with any chemicals?
Porta Pine is conditioned with potable town water to stabilise the fibre. No chemicals or treatments are used in the production process. It is exclusively made from timbers sourced from independently certified, sustainable and renewable forest plantation operations. Porta H3 Treated Pine is treated with an ACQ process which is based on a Copper preservative.
Can Porta's treated pine be used for a pet kennel or externally?
Yes, H3 Treated Pine can be used for a pet kennel or external projects. It is treated with a fixed waterborne copper preservative, known as Alkaline Copper Quaternary (ACQ). This protects against rot, decay, UV and weathering. Any chemical treatment may irritate the skin and it is advisable to seal all surfaces with an acrylic or urethane coating.
