What joist spacing do composite boards need?
Solid-core composite boards usually go on joists at 300–400 mm centres for a residential deck, closer than the 450 mm often used for hardwood. Follow the span table for the board you buy.
Do you deliver Australia-wide?
Yes. 5.4 m boards travel on a pallet by truck, not by courier. Delivery is quoted by postcode before you pay.
Can I get samples first?
Yes, free. We post offcuts of the colours you pick. Request samples.
Can composite decking go in a bushfire-prone area?
It depends on the site's BAL and the board's own fire test. BAL-40 and BAL-FZ need non-combustible decking, which standard composite isn't. BAL explained.
How many lineal metres of decking per m²?
140 mm boards: 6.9 m; 180 mm boards: 5.4 m; 88 mm boards: 10.8 m (5 mm gap).
How many boards for a 3 × 3 m deck?
13 × 140 mm, 10 × 180 mm, 20 × 88 mm boards of 5.4 m, with 10% waste.
Should boards run the long way?
Usually. Fewer joins and less waste, as long as joins land on a joist.
Is composite hotter than timber?
Yes, in direct sun, and dark colours more than light ones. Choose a lighter colour for an unshaded deck.
Does composite need oiling?
No. Wash it with water and a soft brush a couple of times a year.
Which lasts longer?
Composite doesn't rot or need re-oiling. Hardwood can last as long if it's oiled and kept clean; neglected timber usually fails first.
Can I use composite decking in BAL-29?
Only if that specific board has been tested to AS 1530.8.1 and achieved BAL-29. Check the report names your profile.
Is composite allowed in BAL-40?
Standard composite isn't; BAL-40 needs non-combustible decking such as aluminium systems.
Who decides if my deck complies?
Your building surveyor, from the site BAL and the product's test evidence.
