Two philosophies of finish
Every panel begins the same way: a single sheet of 2mm low-carbon steel, laser-cut to a design that will hang on your wall for decades. What separates corten from powder-coated steel is not quality — both are built to last a lifetime — but philosophy. One finish evolves. The other stays exactly as it arrived.
This guide helps you decide which philosophy belongs in your home.
Corten: steel that writes its own story
Corten is not a coating — it is a different grade of steel entirely. Weathering steel contains copper, chromium and phosphorus in its alloy. When exposed to moisture and air, these elements form a stable oxide layer — a patina — that protects the metal beneath from further corrosion. The rust is not damage. It is armour.
The transformation takes six to twelve months. In the first weeks the surface shifts from raw grey to a warm amber. By month three it deepens into burnt orange. By month eight to twelve, it settles into a rich, even russet that no longer changes. Each panel develops its own pattern depending on climate, humidity and mounting position — no two corten panels age identically.
Corten needs no maintenance. No coating, no sealing, no repainting. It belongs outdoors as naturally as it belongs on an interior wall beside warm wood and stone. A piece like the stag emerging from morning mist gains something raw and alive in corten — the material echoes the subject.
Powder-coated finishes: precision that endures
Our powder-coated panels come in three registers: Matte Black, Matte White, and Raw Steel (a transparent protective coat that leaves the grey metal grain visible).
Powder coating is applied dry and cured with heat — baked, not sprayed. The thermal bond gives it scratch resistance and UV stability far beyond wet paint. One decision matters here: we apply powder without primer. Primer floods fine detail. On a design as intricate as overlapping feathers, where lines run thinner than 3mm, skipping primer is not a shortcut — it is a quality choice. Every cut stays crisp.
The result is a finish that looks the same on year ten as it did on day one. No evolution, no patina, no ageing. The colour holds and the detail reads exactly as designed.
How they age: evolution vs. permanence
This is the core difference, and it is worth understanding clearly.
Corten evolves. It will not look the same in six months as it does when you unbox it. The patina is unpredictable in its early stages — it may be uneven at first, darker in corners where moisture collects, lighter on exposed faces. This is normal and temporary. The panel is growing into its final form.
Powder coat is permanent. Matte Black stays matte black. Matte White stays matte white. Raw Steel stays sealed grey. There is no transformation to witness and none to worry about. You hang it and it holds.
A piece like the growth rings of a tree trunk reads beautifully in either register — the organic subject works with corten's living patina and equally with the graphic precision of matte black. The question is whether you want the finish to be part of the story, or a frame around it.
Where each finish belongs
Indoor, dry rooms (living room, bedroom, study): Any finish works. Choose on feeling — the depth of black, the warmth of corten, the honesty of raw steel, the calm of white.
Indoor, humid rooms (bathroom, kitchen, coastal home): Powder-coated finishes. The sealed surface resists moisture without question. Corten can be used indoors in humid spaces, but early patina run-off may mark a light wall if not managed. If in doubt, powder coat is the safer path.
Outdoor, exposed positions (garden wall, terrace, fence): Corten. This is where it was born. Weather makes it better. A corten panel on a garden wall will outlast the fence beside it.
Outdoor, sheltered (covered terrace, balcony under roof): Either works. Powder coat holds outdoors in shelter; corten will still develop patina, just more slowly without direct rain.
Choosing between them
Ask yourself three questions:
- Do I want the panel to change over time? If yes — corten. If you want it to look the same forever — powder coat.
- Where will it hang? Outdoors exposed → corten. Humid indoor → powder coat. Dry indoor → your preference.
- What surrounds it? Warm materials (wood, brick, terracotta) lean toward corten. Clean, modern interiors lean toward matte black or white. Industrial settings suit raw steel.
Price is driven by size and cut complexity, not by finish. Matte Black, Matte White and Raw Steel share the same base price. Corten carries a +20% surcharge because the steel grade itself costs more — it is a different alloy, not just a different surface.
