Timber
H3 treated Victorian ash – as beautiful as it is durable and guaranteed to perform.
Treated to H3 classification (per AS1604 Specification for Preservative Treatment), IronAsh can be used externally in partnership with GoodWood Victorian Ash to allow continuous flow of timber design from inside to out.
Because of the stunning blonde tones of Iron Ash timber, you can stain and paint it to almost any colour. The water-based H3 treatment doesn’t affect the colour of the timber, which means that you can easily match internal joinery with external joinery.
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 and readily available

Sustainability
Using well managed, sustainable timber is the best option to reduce carbon emissions caused by the building industry. IRON ASH (H3 treated Victorian ash) is PEFC certified and stores carbon for life. In addition, Australian hardwood has one of the best Environmental Product Declarations possible, making it the ultimate renewable.
Yes, IronAsh is a combination of our GoodWood Victorian ash that’s been treated to H3 classification. You can use IronAsh profiles in above-ground applications like cladding, screening and pergolas.
Yes, the Tru-Core treatment has a warranty of up to 25 years for decay and insect attack.
Easily match the IronAsh external profiles with our range of GoodWood, Australian Oak and AlpineOak to create a continuous flow of design from inside to out.
