People ask me all the time: "What’s this made of?"
They hold one of our birds in their hands, feel the weight of it, run a thumb along the edge. And then they ask, sometimes suspiciously, sometimes just curious:
"Is it gonna rust?"
Short answer?
It’ll develop a patina.
Long answer?
That’s the point.
Meet Corten Steel
Corten steel isn’t like the cheap stuff you get from big-box garden centres. It’s not spray-painted. It’s not coated in fake bronze or plastic sealant.
It’s weathering steel. Its surface develops a rust patina that helps slow further corrosion in suitable outdoor conditions.
Sounds odd, right? But it’s clever stuff. The patina isn’t a problem... it’s the solution.
Alternating wet and dry conditions help that patina develop. The steel needs airflow and drainage, rather than staying constantly wet.
Ha… think of it like a scab on a cut... ugly at first, but healing you up.
Why We Use It
When I started Metalbird, I wanted to make art that lasted. Not something you’d hang on the wall for a season, then toss in the bin when the paint peeled.
I wanted to make birds that could live outside for years. Birds that would stay put in the wind, fade naturally into their surroundings, and tell a story as they aged.
Corten was the obvious choice.
Weathering steel is also used in outdoor sculptures, bridges and building facades. The location matters: constant damp and salt exposure can affect how it performs.
The patina helps protect the steel underneath. It is not a waterproof seal.
Rust That’s Meant to Be There
We’re used to thinking of rust as bad. Something that ruins your tools or eats the bottom out of your old Hilux.
But Corten’s surface rust... its patina... is different.
It’s meant to happen. And it’s meant to stay.
That rich, natural patina tells a story. It says: "I’ve been here a while."
It says: "I’m part of the landscape now."
It’s not shiny or showy. It’s not about perfection. It’s about weathering with grace.
Steel That Ages Like We Do
One of the reasons people connect with our birds is because they change over time... just like we do.
A Corten bird changes through orange and brown tones as it weathers. There is no fixed timetable or guaranteed final colour. Rain, humidity, airflow and the position you choose all affect the result.
It doesn’t stay static. It becomes part of the place it lives.
That’s life, isn’t it? None of us stay shiny and new. We age. We weather. We carry the marks of where we’ve been. And if we’re lucky, we get to do it gracefully.
Corten steel honours that process instead of fighting it.
Check Your Bird’s Details
Our NZ-made steel birds support local makers. Materials and country of manufacture vary across the wider range, so check the details on the product page for the piece you choose.
This article describes Corten weathering steel. It does not describe every Metalbird product.
It Outlasts Trends
Garden art goes through fads. One year it’s solar-powered gnomes. The next it’s resin mushrooms or plastic butterflies on springs.
That stuff’s fine if you like it... but it usually ends up in landfill by the time the next trend rolls around.
Metalbirds? They’re not trendy. They’re timeless.
Our Corten birds develop a patina in place and gradually blend into their surroundings.
People buy them as memorials, gifts, or markers of moments. Choose a suitable position and follow the installation and care advice for your bird.
It’s not about being flashy. It’s about being solid and real.
Where Should I Put It?
Choose a position with airflow and drainage. Rusty runoff can mark paving, pots and walls, especially during early weathering, so leave room around surfaces you want to keep clean.
Follow your product’s installation and care instructions. For a coastal or constantly damp location, ask us about your particular bird and position.

Why We Love It
At the end of the day, Corten steel is like the birds we make... it’s got resilience built in.
It weathers. It changes. It lasts.
And that’s why we use it. Not because it’s easy. Not because it’s cheap. But because it tells a story of belonging, ageing, and staying put.
It outlasts trends. It outlasts packaging. It outlasts the shiny stuff that breaks before the season’s over.
A Corten bird changes with your garden. Patinaed? Yep. Worn in? Absolutely. That changing finish is part of its character.
