2. Blackbutt (86 x 19/ 130 x 19/ 135 x 32)

Blackbutt Image
Origin NSW/QLD. Truly unique in appearance, one of the lightest of our hardwoods, which allows it to stand up to our harsh climate exceptionally well. Blackbutt is an ideal choice if you are wanting to achieve the natural silvering off effect. Actually harder than Jarrah.

3. Merbau (90 x 19/ 140 x 19)

Merbau Image
Origin Indonesia/Malaysia. By far the best of the imports, simply stunning in appearance with proven durability to withstand our harsh conditions. Deep dark red colours with a unique grain structure highlighted. The ideal choice when combining your deck with Laminated Merbau posts, handrails or staircase. Disadvantage – Rich in tannins which leech out in a red wine like substance, can make a mess of concrete and pavers. If an issue for your build, our design team will advise on preventative measures or alternatives.

4. Spotted Gum (86 x 19/ 130 x 19/ 135 x 32)

Spotted Gum Image
Origin NSW/ QLD. Best characterised by its colour variation, which ranges from pale grey browns and soft creams to a rich chocolate brown. An exceptionally hard timber, Spotted Gum is the ideal choice if you are after a truly unique look for your deck. Disadvantage – Mainly relates to the DIY installer, due to its high hardness level, Spotted Gum is an extremely challenging timber to work with. To find out more talk to one of the Bettawood Team

5. Ironash – Victorian Ash (70 x 19/ 90 x 19)

Victorian Ash Image
Origin Victoria. Blonde, strong and hardwearing this decking board is the only hardwood on the market that is H3 treated, which gives it a 25-year guarantee. Available in solid and Finger-jointer. The finger joint is done in a way to give the board the appearance of one continuous piece, the beauty of the finger joint also means this board comes in set 6 metre lengths, the only one on the market. The consistent blonde colour gives a rich soft look that also lends itself to the natural silvering off look that is very popular today.

6. Karri (65 x 20/ 85 x 20/ 130 x 20)

Karri Image
Origin Western Australia. A close relation to Jarrah, Karri is similar in appearance, hardness and durability. Its characterised by a vibrant red appearance with overtones from pale pink to rich reddish brown giving it a unique colour variation. Great choice when combining your deck with horizontal screening as the 65x20 boards come in a range of set lengths.

Bettawood Built Decks –Key Design Points


Deck substructures are generally treated pine timber, posts/stumps are treated to a H4 Level whilst all joists and bearers to a H3 Level. All joists and bearers are a kiln dried treated pine which provides great stability and durability for the decking above, resistant to rot and termite attack, a treated pine substructure provides the best and most economical option available.

- Guaranteed Durability

All Bettawood substructures ae backed by a 25 year limited guarantee against termite and fungal attack.

Alternative Substructures

Deck substructures that require an alternative timber to treated pine due to bushfire zoning or greater engineering requirements, Bettawood have a range of options available. Hardwood substructure options include:

- Ironash (Victorian Ash) F14 (Available in 7.2m lengths) New laminated hardwood that gives superior strength in a H3 treated finish, ideal for decks requiring large spans. Drastically reduces the number of stumps required, double the nail holding ability of treated pine. Head to Products Bettawood Build with for more info.

- Cypress Pine – Dressed and Rough sawn

**Note: Bettawood do not use nor recommend steel frame substructures due to the differing rates of movement between steel and timber.

Wide Boards

Got a deck area greater than 4m in width? Then the wide decking board could be the perfect option, ranging in width from 130mm-140mm. This is the ideal alternative to the standard 85-90mm board which when laid over a large area (more relative to width than length) can make the deck area appear “busy”, the wider board will overcome this and provide a fantastic look. **Note: The wider board is not suited nor recommended in low lying area with minimal clearance and poor ventilation, our design team will advise if this is the case.

Decking Fastening

Our preferred fastening system are stainless steel screws; this ensures the strongest fastening method for securing the decking board to the joist. The choice of screw will depend on decking application. For the perfect finish we use a Countersink bit with a depth gauge, which allows for the screw to sit below the deck level. This gives a great finish and allows for any re-sanding of the deck at a later date

Our design team will consult with you ensuring the correct screw is used for your build. Our extensive range of screws are all on display at our Glandore showroom.

Bettawood do not use nor recommend concealed fixing systems on our timber decking, due to the natural movement of timber coupled with our harsh climate, the long term viability of a concealed fixing system is something we cannot guarantee.

Design Points
There are 2 styles of stair construction that Bettawood design and build with, which our design team will discuss with you in choosing the appropriate construction for your project

Boxed Decking Step Construction:

This design creates a look that will match your deck. Ideally we like to keep this design to a maximum of 2-3 steps due to the framing layout required to box out the steps.

Stringer and Tread Stairs:
This is the more traditional method of construction for stairs, a key design point that Bettawood implement in this construction is that we rebate our treads into our stringers.

PowerPrepTimber Finishes

Bettawood have a large range of Timber Finishes available when it comes to protecting and enhancing your timber project. Our experience team will talk you through all the options available. We also have our working displays of decking and screening located at our display yard.
