Start with substance.
Why composite? These boards need no sanding, staining or painting, and clean with soap and water. We chose one range over a little of everything.
ABOUT DECKING ONLINE / 01
Good spaces begin with good choices.
We keep the range short, the details exact,
and the order easy to get right.
OUR STARTING POINT / 02
A deck is more than the boards you choose. It is the morning coffee, the weekend project, and the extra room that brings your home outdoors.
It is also a surprising number of small decisions. Which edge. Which clip. Which screw, in which colour, for which frame. Get one wrong and the job stops while the right part arrives.
Decking Online exists to make those decisions plain. One composite decking range, chosen with care. Every fixing it needs, sorted by the frame you are building on. Sizes, coverage and prices stated in full, so the order you place is the order you meant.

A short range, exact information, complete orders.
The foundations of a clearer choice.
Why composite? These boards need no sanding, staining or painting, and clean with soap and water. We chose one range over a little of everything.
Every board is listed with its real size and one honest length. Every pack says roughly what it covers. Every price includes GST.
Tell us your frame once and the clips and screws narrow to suit. Choose a board colour and the matching screw is one link away.

WHY WE START WITH TREX / 04
From warm timber tones to quiet greys, Trex® composite decking gives a house several ways to meet the garden. Transcend® carries the deep grain and the stronger colours. Lineage brings a streaked grain in four more.
Each comes as a groove board for hidden fixing and a square edge board for borders and stairs, with the clips, screws and plugs to fix it. Explore the grain, check the size, and find the fixings matched to your colour and your frame.
Explore Trex deckingBoards carry the manufacturer’s 50-year limited residential warranty, including fade and stain, and 10 years for commercial use. Terms apply. Follow the manufacturer’s installation and care guidance. Colours on screen are a guide.
GOOD TO KNOW / 05
A few practical things to think about before you choose.
Look at what is already there: brick, paint, paving, planting. Decide whether the deck should blend with the house or contrast with it, then shortlist two or three colours and compare them side by side. Remember that colours on screen are a guide, because screens and print vary. Explore the colour palette.
The length and width of the deck, the direction the boards will run, and anything that breaks the rectangle: stairs, posts, cut-outs, a picture-frame border. Boards are 5.48 m long and are cut on site, so your installer will work out how many whole boards the layout needs.
The frame is what the boards are fixed to: timber joists, or aluminium or steel ones. Clips and screws are made for one or the other, so it is the first thing we ask when you shop for fixings. Find fixings for your frame.
Clips for the groove boards, starter clips or screws for the first row, colour-matched screws for square edge boards, and joist tape for a timber frame. Over a slab or a membrane, add the pedestals and joists. Discuss the complete project, including any approvals, with a suitable installer.
