Ironash Timber: The Perfect Exterior Solution

IronAsh uses innovative technology to combine a transparent combination of water based additives deep into the core of GoodWood Victorian Ash. Suitable for external use, IronAsh includes a range of profiles for cladding, battens, pergolas and more.


Treated to H3 classification, IronAsh can be used externally in partnership with GoodWood Victorian Ash to allow continuous flow of timber design from inside to out.

IronAsh is a great choice to finish the project. It can be easily cut, stained and painted on site. The IronAsh range offers an affordable timber choice that is stable, readily available and complies with AS1604 Specification for Preservative Treatment.

Iron Ash Battens & Screening

Iron Ash Sub decking

A strong, straight and long option for bearers and joists with double the nail holding ability of treated pine.
Available in random length longs or set length up to 7.2m.
A deck of 4800 x 7200mm at 1.0m and above using IronAsh bearers and joists can require only 15 stumps as compared to an F7 treated pine which can require up to 35 stumps. The cost of material for each product is similar but the difference is clear. Not only will this save a day in labour but a hardwood joist has double the nail holding ability of treated pine which ensures the quality of your deck for years to come.
