135x35 mm Ironbark is the heavy-duty board in our Ironbark decking family: nearly twice the thickness of the standard 19 mm profile, specified for commercial decks, wider joist spacings and high-traffic structures where extra section depth is wanted from the hardest common decking species. A 140x35 mm board is available at the same linear-metre rate; choose the width in the buy box.

Sold as QLD Class 1 Hardwood: the supplier specification sheet publishes Class 1 above-ground natural durability with a 40+ year service expectation, with deep grey-brown colour and exceptional density. This thick profile is supplied against our supplier's published thick-decking range for Ironbark; it is a specialist profile that is less commonly shelf-stocked than the 19 mm boards, so availability and lead time are confirmed with our supplier at quote stage.

Sold per linear metre in random lengths. Preferred lengths, packs and bulk quantities are quoted against current supplier availability: add your linear metres to the cart, or request a quote for project volumes.

Calculating for: 135x35 mm Ironbark Hardwood Decking

Calculator mode
Area to linear metres

Supplied in random lengths, so there is no length to choose: order the total linear metres you need.

Enter your measurements and select Calculate to see an estimate.

How this is calculated

Cover width (m) = (board width + gap) ÷ 1000

Linear metres required = area ÷ cover width

Linear metres with wastage = linear metres × (1 + wastage ÷ 100)

Reverse: estimated coverage area = linear metres × cover width

Estimates only. Confirm final quantities against your measured plans and the product's actual cover width before ordering.

Applications

Decking, screening, battens, heavy outdoor structures and high-traffic decks.

Installation
  • Store boards flat, fully supported and off the ground, and keep them dry before installation. Allow the timber to acclimatise at the site before fixing.
  • Fix with hot dipped galvanised or stainless steel screws, two per joist, pre-drilled and countersunk. Stainless steel fixings are recommended for coastal or poolside work.
  • Maintain ventilation gaps between boards and adequate ground clearance so the deck can dry out; the supplier installation guidelines under Documents and downloads set out clearances in detail.
  • Use sharp, quality cutting tools and seal cut ends with decking oil. Wear appropriate eye, ear and breathing protection when cutting.

Maintenance
  • Clean the surface before coating; an oxalic acid based timber cleaner removes dirt, grease and tannin stains.
  • Finish with a penetrating decking oil per the coating manufacturer's label, then re-coat on a regular cycle suited to exposure and traffic.
  • Monitor the coated timber for colour loss and dryness, and re-coat when it begins to look dry to maintain protection.
