Know the Best Variety of Decking Materials from Prestige Construction and Design

16 December 2021

The deck of a house is a kind of home extension, where you utilise and convert a space into an area with functionality. As decking projects become prominent in Australia, there has been tremendous progress towards the material choices used to build a deck. From wood to composites, building a deck out of specific materials can bring some advantages and disadvantages to you and your property.

Pressure Treated Lumber

Perhaps the most preferred material for decking projects, pressure-treated lumber is milled from southern yellow pine and then treated to resist rot and pests. This material is affordable and can be found almost anywhere, making it popular among homeowners and home builders. Moreover, nails and screws can be cut and fastened into this material with ease.

Alternatively, the pressure-treated lumber doesn’t look appealing compared to other decking materials. And despite any treatment, this material can still crack, split, and warp according to the surrounding environment. There would also be some risk of shrinking and twisting when you choose the cheapest pressure treated lumber in the market, making this expensive to maintain and repair.

Redwood and Cedar

Unlike pressure-treated lumber, the redwood and cedar bring a natural beauty that can be appealing for homeowners. These materials have vibrant colours that can enhance the appearance of the property. Also, both wood materials contain tannins and oils that protect them from rot, decay, and pests.

The richness of colour and resistance to harmful agents make the redwood and cedar three times more expensive than the pressure-treated lumber. The resistance of the materials has limitations as well since the location of the heartwood and sapwood determines their resistance level. Also, preserving the materials’ colour requires the application of stain. Without this, both materials will weather to a silver-grey.

Tropical Hardwoods

From the name itself, tropical hardwoods came from materials found in the tropics.

Some examples of this material are ipe, cumaru, tigerwood, massaranduba, garapa, Bambara, Philippine mahogany, and red tamari. Just like the previous materials, tropical hardwoods can resist rot and insects. They are also hard and durable, making them a great choice with deck projects.

Of course, tropical hardwoods have their weaknesses. The durability of tropical hardwoods makes it difficult for nails and screws to go through without any pilot hole borings. Moreover, tropical hardwoods are more expensive than pressure-treated lumber but are priced almost the same as redwood and cedar. Lastly, this material doesn’t accept any type of stains very well. You must go for an oil-based penetrating stain for the protection and coating of the material.


Despite being manmade, the combination of wood fibres and recycled plastic of the composites makes the material resistant to any weathering factors, stains, cracks, splits and rotting compared to others. Additionally, the production of this material is defect-free, which eliminates the need to get rid of unused materials. However, a disadvantage of using composites is the presence of mould and mildew over time. Moreover, this material is still susceptible to decay in the long run since composites are partially made of wood.
