An old favorite, timber decking. There’s nothing that quite beats the look of timber decking around your pool, garden, walkway or under your verandah.

At Australian Treated Pine, we stock a range of timber decking in both treated Pine and Merbeau. As with all timber decking, it is very important that your sub floor (bearers and joists) are correctly installed to accommodate your decking. The maximum spacing on your joists centers (distance between the joists) must not exceed 450mm (18 inches). Should your spaces exceed this distance you will experience “bounce” in your deck and in some cases you may even have breakages under load.

All timber decking stocked is what is commonly marketed as a “reeded reversible” decking pattern or profile. That means, one side of the decking is reeded (in other words has grooves machined in it) and the other side is plain or smooth in its finish.

It is a widely held misconception that the grooves provide a “non slip” surface for use in wet areas. This is not the case! In fact the reason decking has grooves machined in it is to reduce surface contact between the decking itself and the joist, thus preventing water from being held between the two surfaces and preventing premature decay. On this basis, we recommend you install your decking plain side up. However, ultimately, the choice is yours!

Treated Pine decking is available in 70mm width and 90mm widths, 20mm thick. Treated Pine decking is now treated with ACQ (alkaline copper and quaterny. Refer to technical info on this site for more information) in accordance with legislation. Treated Pine is available in both “Wet” and “kiln dried” finishes. If you intend to use wet decking you will need to anticipate shrinkage in your decking boards. Treated Pine decking is available in set lengths; please ask our sales staff for advice on available lengths. If you are using short lengths I.e. 600mm, 900mm, 1200mm, 1500mm, 1800mm, you may be entitled to a discount, so please order short lengths if that’s what you require, It may be cheaper!

Merbau decking is available in 70mm, 90mm and 140mm widths and is also 20mm in thickness. Merbau is a dark red or even Brown type of color. Merbau is available in random lengths only (That means you cannot specify the exact length that you require).

Fixing your decking is very important. Many decks have been ruined through the use of inappropriate fixing materials and methods. The best way to fix your deck down is to use screws, followed closely by hand nailing it. When using either method, you should always pre drill your hole to approximately 75% of the diameter of the fixing that you intend to use. This will prevent splitting of your timber when installing. When you are selecting a fixing product, the best finish is stainless steel, followed by hot dipped galvanized products. If you are using a nail, we recommend a Tidadeck nail. Tidadeck nails have a “twist” or helical thread, helping to prevent the nail from working its way back out, with a rounded head they are also “foot friendly”! Please ask our expert staff for more advice on fastening products.

Note: When using treated Pine decking, definitely do not use aluminum fasteners or have any aluminum products in contact with the decking boards.

Do not use plain steel fixings as they will rust, both reducing the capacity of the fixing and staining your decking.

Do not use a nail gun unless it is specifically designed for use with approved timber deck fixing products as described above.
