5 Tips for Buying Treated Pine Decking in Australia

What ongoing maintenance schedule would you recommend to maximise the life of your decking and landscaping timbers: cleaning, re-coating, and inspections?

Regularly sweep your deck and wash it with mild soap and water when required, being sure to avoid harsh chemicals and high-pressure washes that may cause damage to the timber. Apply a good-quality sealant or decking oil every 1–2 years for protection against water and UV damage. Check annually for splits, rot, or loose fixings, and resolve any issues quickly before they can worsen. Ensure the area is well-ventilated, trim back nearby plants, and ensure that water drains away correctly to avoid pooling.

Are there any fasteners, brackets or other hardware that you specifically recommend or advise against using with your treated pine products?

Use hot-dipped galvanised, stainless steel (304 or 316 grade) or other corrosion-resistant fasteners with all our treated timber. Avoid standard mild steel fixings, as they’ll corrode quickly, especially with ACQ-treated timber, which is more corrosive to metal than CCA. For coastal or high-moisture environments, stainless steel is your safest bet. Check that brackets and joist hangers are also appropriately rated – your local hardware supplier can match fasteners to the treatment type and application.

Do your treated pine products meet the relevant Australian Standards for structural and outdoor use, and can you provide documentation for builders, certifiers or council?

Yes, all our treated pine meets the Australian Standard AS/NZS 1604 for preservative-treated timber. Treatment certificates and compliance documentation can be supplied for builders, certifiers, and council submissions. Products are clearly marked with their hazard class rating and treatment details. If you need specific paperwork for a project – whether it’s for building permits, engineering sign-off or warranty purposes – just let us know at the time of order and we’ll organise the right documentation.

What sort of certifications or sourcing practices back up the sustainability and environmental side of your timber range?​

We’ve been supplying sustainable Aussie timber for over 30 years, and we only source plantation-grown pine from responsible, certified suppliers. Our range is some of the most sustainable timber you’ll find in the country, and we’re serious about eco-friendly practices right across the board. Plantation pine is a renewable resource grown specifically for timber, so you’re not touching native forests. If you need the nitty-gritty on certifications or supply-chain paperwork, give our team a buzz and we can chat through what your project needs.​

What do I need to watch out for when handling, cutting or getting rid of CCA-treated products, especially if I’m doing a DIY job at home ?

When cutting or sanding CCA-treated timber, always wear gloves, a dust mask and safety glasses to avoid inhaling sawdust or getting preservative on your skin. Work outdoors or in well-ventilated areas, and clean up sawdust thoroughly – don’t burn it, as the smoke releases harmful chemicals. Wash hands before eating or drinking. For disposal, treated offcuts can generally go to regular landfill, but check with your local council first. Never use treated timber for firewood, garden mulch or compost.
