Timber
H3 treated American Oak – an exterior solution designed for the Australian climate
There’s nothing like the warmth and beauty of timber. It’s natural, sustainable and durable which is why we’ve created IronOak, America’s favourite hardwood designed for external use.
IronOak is the perfect choice for those after a blonde, select grade and crown-cut exterior hardwood. The unmatched style and quality of our IronOak means that it is capable of uplifting any façade, all while withstanding the diverse local climate.
Treated to H3 classification (per AS1604 Specification for Preservative Treatment), IronOak is handpicked by region and colour, graded and processed to exceed Australian standards and supplied in small, manageable packs.
Designed to match our internal Glacial Oak (American Oak) range, IronOak is vastly available in a variety of cladding and batten profiles.
