304 vs 316 Stainless Steel for Outdoor Sculpture
The grade decision costs little at the quotation stage and a great deal once a piece starts pitting. Here is how to make it properly.

Why the gold on these panels is a vacuum deposited coating rather than paint, and what that means in a working interior.
PVD stands for physical vapour deposition. The polished stainless panel goes into a vacuum chamber where titanium is vaporised and deposited as an extremely thin, extremely hard layer bonded into the surface. A gold coloured lacquer sits on top of the metal. A PVD layer is part of it.
Gold coloured paint scuffs on handling, dulls under cleaning and chips at edges where people brush past. A PVD coating takes normal commercial cleaning and daily contact without losing its tone, which is the whole reason it is used on panels within reach of seated guests.
PVD is thin enough to follow the surface underneath exactly. It cannot hide a scratch, a weld line or an uneven brush direction. Everything that matters about the polish has to be right before the panel goes into the chamber.
Tone varies slightly between chamber loads, which matters when a feature wall is made of many panels. Panels for one wall should be processed together and matched against a physical reference under daylight rather than described in words.
A soft damp cloth. Abrasive pads will eventually dull a PVD surface, and there is no re-polishing a coating that thin. The good news is that ordinary dirt and fingerprints come off easily.
PVD is harder and far more economical over large areas. Solid brass has more depth in the tone and ages in a way a coating does not. For a large feature wall, PVD on stainless is usually the right answer. For a small object where the material itself is the point, brass is.

Other tones are available through the same process. Ask with your enquiry and a sample can be matched before the full run is coated.
