When building a deck, a common confusion that every homeowner faces is selecting the right material. The main confusion lies between treated pine and hardwood, as both are ideal for outdoor spaces and are known for their low maintenance requirements. Selecting the right material will determine the investment needed for deck building and the stress you will face. Both these materials have a strong reputation for withstanding the harsh Australian climate, but they are also very different in terms of durability, cost, appearance, and upkeep. This guide provides you with a detailed breakdown of both these options to select the one that matches your lifestyle, budget and design goals.
TREATED PINE DECKING
Treated pine is a softwood timber that is pressure-treated with preservatives to make it immune to weather conditions, pest attacks, rotting, fungi, and decaying. This treatment process significantly extends its lifespan and makes it ideal for indoor/outdoor use anywhere in Australia. Some key benefits of using treated pine for deck construction are reviewed below.
TREATED PINE IS AFFORDABLE AND VERSATILE
Treated pine is one of the most budget-friendly decking options available on the market. Using this material allows homeowners to create large, outdoor areas without overspending on the project.
SUPER EASY TO WORK WITH
This wood has a soft texture that makes it simple to cut, drill, design and install. According to treated pine suppliers, working with this wood is easy, even for a DIY enthusiast, provided you have adequate knowledge and suitable tools.
CUSTOMISABLE FINISH
Treated pine can be stained, painted or oiled to achieve any kind of look you want for your outdoors. You can provide it with a natural tone and even some modern finishes, and at the same time, ensure that the colour is preserved and there are no warping issues.
IT IS A SUSTAINABLE CHOICE
Most of the treated pine used in Australia comes from responsibly managed plantations. This is why it is considered an eco-conscious option, and moreover, it does not require any significant maintenance or upkeep. Yes, proper care will be needed to prevent its weathering.
HARDWOOD DECKING
Hardwood is a dense timber, and species such as Merbau, Spotted Gum and Jarrah are used to produce it. These species are popular for their rich colour and impressive strength, and these two features make hardwood a premium choice for outdoor spaces like decking. Some fantastic features of hardwood are reviewed in detail below.
EXCEPTIONAL DURABILITY
Hardwood is naturally resistant to insects, pests, decay and the harshness of the surrounding nature. It can perform well in hot and humid conditions and in coastal areas as well, you will find hardwood performing very impressively.
HIGH VISUAL APPEAL
The natural grain and deep hues of this wood add a unique warmth and sophistication to outdoor designs. With the kind of appeal, you will surely find your deck enhancing your property's curb appeal and its resale value.
LONG LIFESPAN

LESS FREQUENT MAINTENANCE
