Introducing ASH Classic Grade Timber

Character and Warmth with ASH Timber

When it comes to timber that delivers strength, workability and a natural warmth, Australian Sustainable Hardwoods (ASH) classic grade timber offers that and more. Designed to expose the timber’s character, this visual grade celebrates the natural marks, tones, and imperfections while providing a more cost-effective option for builders and trades. In this blog we discuss this visual grade and the advantages of using classic grade timber by ASH.

What is ASH classic grade timber?        

Classic grade isn’t about uniformity. It’s about highlighting the imperfections of the timber that give it character. You’ll find natural features like gum veins (both tight and loose), gum pockets, knots, pinholes, burls, minor splits, and surface checks. These details aren’t flaws – they add warmth and individuality to every project and showcase the timber’s life.

What are the benefits of using classic grade timber?

Whether you’re working on timber cladding or internal wall lining, classic grade delivers practical benefits such as:

• Straight edge for ease of installation
• Stored carbon
• Machines well for clean cuts and smooth finish
• Stains well for a custom result
• Exceptional strength for structural durability
• Sustainable choice minimising waste
• Treated for insect protection (IronAsh only)
• Externally durable with H3 water-based treatment (IronAsh only)

Why Use classic grade?

As demand grows for timber with visible grain and character, ASH is maximising the use of logs that once might have been exported or pulped for paper. This approach means less waste, more local jobs, and a steady supply of premium hardwood for Australian builders. Choosing classic grade supports a sustainable, responsible timber industry without compromising on performance.

What is Australia Oak?

Australian Oak is ASH’s brand of Tasmanian Oak, a blend of three species: Eucalyptus regnans, Eucalyptus delegatensis, and Eucalyptus obliqua. Known for its stability, versatility, and light colouring.

What is IronAsh?

IronAsh is essentially Australian Oak with a H3 water-based treatment that makes it resilient enough for external use. It provides protection against decay and insects yet keeps its natural appearance. Backed by a 25-year guarantee, IronAsh is ideal for external projects.
