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.

"Bronze" on a color chart isn't one fixed shade — mill runs and finishing processes shift the tone from a classic warm brown to a lighter rose-brushed hue, a cooler weathered grey, or an olive-gold sheen. We work across four bronze tone families, so you can match the exact warmth or depth your project calls for.
