Our Polished Marine Stainless Steel is grade 316 and manufactured with high concentrations of chromium and nickel. These products offer great strength and have extremely resilient corrosion resistant properties which make them an excellent choice for coastal locations. This finish is very versatile, with a high sheen appearance that works well with warm tones and cool, contemporary settings alike.
