High Quality Cold Stainless Steel Color Coil 304 304l 316 316l 321 Stainless Steel Color Roll Price
The color displayed on the surface of colored stainless steel coils depends on the chemical composition, organizational structure, smoothness, film thickness and incident light of the surface oxide film. The thickness of the oxide film of colored stainless steel coils is generally 200~400nm. The oxide film is thin and appears blue or brown; the oxide film of medium thickness appears golden yellow or red; the thick oxide film appears green or even black. The emergence of colored stainless steel has greatly enhanced the application range of stainless steel.
