Where it is installed

Applications

Three places where oxidised copper regularly ends up, and what is different about each of them.

Indoors

Wall cladding and panels

Indoors the tone comes into its own, because it stays the way it was delivered. No rain, no sun, no further development of the layer. What you approve is still on the wall in exactly that state years later.

We supply the sheets cut and folded, in the formats your substructure needs. Joint pattern, fixing and edge detail are agreed before oxidising, because a fold made after colouring no longer comes out cleanly.

TypicalWall claddings, niches, ceiling rafts, linings on built-in elements.

SequenceCutting and folding first, the surface after.

TouchAt hand height and on handrails every metal surface picks up marks over time. We tell you beforehand what to expect.

Outdoors

Façade cladding

Outdoors the weather carries on working. An oxidised façade starts in the tone you chose but darkens over the years. On vertical surfaces that usually ends at an anthracite brown, which is the final colour state there.

Anyone who knows that plans for it. Anyone who does not is surprised after five years. So it says so here and not in the small print: the tone ex works is the beginning, not the end.

Colour pathThe chosen tone darkens over the years; on vertical surfaces it usually ends anthracite brown.

Drip edgeWhere a pitched surface meets a vertical one, one belongs in between. Otherwise run-off water carries the colour development with it.

BelowWater running over copper picks up dissolved compounds. Over pale natural stone, fair-faced concrete or render that can leave veils.

Other metalsCopper is nobler than aluminium, zinc and galvanised steel. In contact and with moisture it attacks the less noble metal.

Notes on colour development, water management and metal contact follow the German Copper Institute information sheet i.30.

One-offs

Furniture, desks and art in architecture

Small surfaces are the most rewarding. That is where you see the texture that disappears on a façade seen from twenty metres.

Fronts and carcassesFurniture fronts, plinths, sliding doors. The tone becomes the material, not a coating.

Reception desksA large continuous surface, often under artificial light. Well worth looking at the sample under the planned lighting first.

ObjectsArt in architecture, wayfinding, signage. Welded and formed parts take the surface too.

One-offsEvery surface is made by hand. Two parts look similar but never identical.

Not for this

Where oxidised copper does not belong

On pitched roof surfaces the path leads to patina green over the years, because precipitation stays there longer. If you are planning a roof surface in green, copper patina is the right route, not oxidising.

And what we do not offer: colouring on the building site. Under site conditions a large surface turns out patchy, and the layer usually does not stand up to the weather. We deliver finished components; installation is done by your own contractor.
