Mirror Finish Precision Stainless Steel Strip 304L 316L Custom Width

High-Precision Stainless Steel Strip, Mirror Finish, Custom Widths up to 500mm

High-Precision Stainless Steel Strips with mirror finish and customizable widths up to 500mm are engineered for industries requiring flawless aesthetics and exact dimensional tolerances. Made from premium austenitic grades like 304L and 316L, these strips undergo advanced cold-rolling and precision polishing processes to achieve a reflective surface (Ra ≤0.1μm) and thickness accuracy within ±0.005mm. Ideal for applications demanding both visual appeal and functional reliability, they are compliant with international standards such as ASTM A480 and EN 10088. Custom widths (10–500mm) and hardness levels (HV 150–400) cater to specialized needs in sectors like electronics, aerospace, and luxury décor, ensuring versatility and performance in extreme environments.
