Decking timber in Melbourne

Greenhill Timbers stocks decking at our yard at 170 Settlement Road, Thomastown, with pickup or delivery across Melbourne and regional Victoria. Merbau has been the yard’s specialty from the start, and the range now runs from Australian hardwoods to composite boards that never need oiling, with the joists, stirrups, screws and oils to build the whole deck from one place.

Timber decking

Merbau decking in 90, 140 and 190 × 19 mm, kiln-dried, Standard and Better grade, in set lengths, random lengths and long 4.2 to 5.7 m lengths, from $5.30 a metre for 90 × 19. Spotted Gum, Blackbutt, Ironbark, Grey Box and Silvertop Ash in 86 and 135 × 19 mm. Merbau, Spotted Gum and Blackbutt are accepted to BAL-29 in 19 mm boards for bushfire zones.

Composite decking

Trex, TimberTech, NewTechWood, ModWood, WoodEvo, EVERTEX and Ultim8: capped composite and PVC boards in grooved and square-edge profiles with matching fascia and clips, from $72.50 a board. No oiling, no splinters, and brand warranties that run to 25 years and beyond.

Frame, fixings and finish

H3 treated pine joists and bearers, LVL for long spans, and the galvanised stirrups, joist hangers, KlevaKlip supports, decking screws, concrete and stumps in decking accessories. For a frame that cannot rot, see the ClickDeck aluminium subframe. CUTEK, Intergrain and Sceney’s oils and cleaners are in decking oil and paint.

Planning a deck

Joists at 450 mm centres, or 350 mm when boards run at 45 degrees. Gap 86 to 90 mm boards at 3 to 4 mm and 135 to 140 mm boards at 4 to 5 mm. Allow about 11 lineal metres per square metre for narrow boards and 7 for wide ones, plus 5 to 10% for cuts. Decks over 800 mm high or attached to the house generally need a building permit in Victoria; our deck permit guide covers it. Bring your deck size in, or call (03) 9465 9875, and we will work out boards, lengths, fixings and oil.
