Bronze Stainless Steel 

Sanmei Metal Supplies bronze stainless steel sheet and coil in Classic, Amber, Smoky, and Bronze Gold tones — PVD coated, grades 201, 304 and 316, for indoor and outdoor use.

Bronze stainless steel isn't a separate alloy — it's a standard grade (201, 304, or 316) with a bronze-toned surface applied on top. The color comes from two processes: Recubrimiento PVD, a thin, wear-resistant bronze-colored layer vacuum-deposited onto the base finish (brushed, mirror, or textured), and water plating, an electroplated bronze or copper tone used mainly on our antique and hammered finishes for a deeper, aged look — see our Antique Finish process → for more on how that's done.

Either way, the base metal underneath stays fully stainless — the bronze color sits on the surface, so you still get stainless steel's corrosion resistance, not a bronze alloy's properties.

The baseline bronze tone — a balanced warm gold-brown that reads as true bronze under both indoor and daylight conditions. The reference point the other three tones are measured against.

Balanced tone, versatile lighting performance, easiest color match across large orders.

Hotel lobbies, feature walls, general architectural cladding.

The deepest, most muted tone in the bronze range — a darker, low-reflectivity bronze that leans toward shadow rather than shine.

Low glare, hides fingerprints and handling marks well, understated look.

High-traffic elevator interiors, commercial door hardware, minimalist interiors.

Pushes the warm end of the bronze spectrum — brighter and more golden than Classic Bronze, closer to a metallic gold with bronze depth underneath.

Higher light reflectivity, stronger visual warmth, premium/luxury read.

Reception desks, retail displays, luxury hardware accents.

Lighter and warmer than Classic Bronze, with an amber undertone that stands out more clearly under warm/indoor lighting.

Warmest visual tone in the range, strong performance under warm-white lighting.

Restaurant interiors, boutique retail, residential kitchen accents.

Base coils come from our TOP partner mills (Lisco, Tisco, Jisco, Posco PZSS, Yongjin, Hongwang) before undergoing surface finishing and coating in-house at our Foshan facility. 

Every sheet and coil ships with protective PVC film from Polifilm (Germany) and Novacel (France). Adhesion level is matched to your downstream process — strong enough to stay in place through laser cutting or stamping without gas pressure lifting the film and causing edge blowout, but not so strong that it leaves residue when removed.

Seaworthy packaging using sturdy wooden crates or steel frames to ensure 100% surface perfection upon arrival. Exporting directly to North America, Europe, Middle East, and Southeast Asia.
