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: PVD coating, 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.

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.
