Composite Decking

Composite Decking Melbourne – A Practical, Long-Term Solution for Outdoor Builds

Composite decking has earned its place as a go-to material for modern outdoor projects. It gives you the look of timber without the ongoing upkeep, making it a strong choice for busy homes, public spaces, and anywhere the deck needs to stay sharp over time.

At Greenhill Timbers, we stock some of the best-known composite ranges on the market, all handpicked for durability, slip resistance, colour stability, and ease of installation. Whether you're building in the suburbs, by the coast, or in a high-traffic commercial zone, you'll find a board that holds up well under pressure and keeps its finish year after year

What You’ll Find In-Stock

We carry a wide range of composite decking in Melbourne, including but not limited to:

• NewTechWood : Known for its natural texture and wide colour range. Options like Antique, Teak, Walnut, and the Coastal Range work well in modern and coastal-style builds. Offers both grooved and square edge boards, with concealed fixing systems available.
• ModWood & ModWood XTG : Locally made composite with high resistance to moisture and expansion. Often used in pool decks and public boardwalks. UV stability is a strong point here.
• TimberTech : We stock several collections — Landmark, Legacy, Terrain+, Vintage. These are fully capped boards with a realistic timber feel and strong fade protection. Ideal when the finish matters or for high-end residential projects.
• Trex Decking (Carmel & Jasper Lineage) : One of the most recognised names in composite. Boards are fade- and stain-resistant, with uniform surface tone. Used in both homes and high-use commercial decks.
• Ultim8 Decking : A straightforward option when the job needs something simple, solid, and low-fuss. Works well for standard alfresco decks or low-level walkways.

Each range includes different grain styles, edge profiles, and fixing systems. Some clip in, others screw down. If you're unsure, we’ll help you determine which one will best suit your project.

Why Builders Choose Composite for Decking

• No oiling, sealing, or sanding needed
• Won’t cup, crack, or grey off like hardwoods
• Surface stays cooler and splinter-free
• Resistant to rot, termites, and moisture
• Most options are made using recycled timber fibres and plastics
• Boards hold colour and don’t vary as much from batch to batch

Just be aware — not all boards behave the same. Some handle expansion better than others. Some clip systems are quicker to work with. Connect with us for more information.

Colours and Profiles

We stock a broad range of tones — brown composite decking in rich timber-style finishes, black composite decking for more contemporary builds, plus lighter greys and natural oaks.
