The Ultimate Guide to Corten Steel: From Weathering to Wow Factor

If you’ve spotted those striking rust-coloured planters, screens or fire pits around Canberra, you’ve already met Corten steel. This material isn’t just beautiful—it’s engineered to thrive in Australia’s harsh climate. Here’s everything you need to know before choosing Corten for your next landscaping or architectural project.

What Is Corten Steel?

Corten (short for CORrosion resistant TENsile steel) is a high-strength alloy that forms a protective patina when exposed to the elements.
Initial Stage: The surface begins as standard grey steel.
Weathering Process: Over weeks to months, it develops a warm, rust-like layer.
Permanent Barrier: This patina seals the steel underneath, dramatically slowing further corrosion.

Why Landscapers Love It

Built for Australian Conditions
Canberra’s hot summers and frosty winters won’t crack or peel Corten. The protective layer actually gets stronger with time.

Low Maintenance
No painting or sealing required. A quick rinse to remove debris is all you need.

Timeless Design
The earthy, burnt-orange finish pairs beautifully with native plantings, stonework and contemporary architecture.

Arkus Industries & Corten

At Arkus Industries in Fyshwick, we cut, fold and fabricate Corten steel for:

• Garden Edging & Rings – Create crisp, durable borders.

• Modular Planters – Re-configure layouts seasonally.

• Fire Pits & Screens – Our ArkuFlame range doubles as a statement piece for outdoor entertaining.

Because we manufacture locally, you get Australian-made quality, shorter lead times and the option to customise thickness, size or design.

Tips for Using Corten in Your Garden

• Plan Drainage: Good airflow and drainage help the patina form evenly.

• Mind Run-Off: Place edging or planters where minor surface staining on pavers or walls won’t matter during the first few months.

• Mix & Match: Combine with timber decking, gravel paths or polished concrete for a balanced look.
