In the application of stainless steel, surface treatment is a vital link. It not only determines the appearance of stainless steel products, but also affects their functional properties. Whether in visual effect or actual function, the right surface treatment can bring significant enhancement to your design and products.
Understanding the various types, processes, selection points and maintenance methods of stainless steel surface treatment is of key importance to fully utilize the advantages of stainless steel and meet the needs of different application scenarios. This guide introduces the main characteristics and uses of common stainless steel finishes in the manufacturing process.
I. Stainless steel surface treatment type
(1) Brushed surface treatment
Brushed finishes are formed by wire brushing and leave tiny parallel marks on the stainless steel surface, giving a soft, non-glare appearance. This finish is commonly used for kitchen utensils, architectural panels and equipment that require less fingerprint residue. Due to its unique texture and visual effect, it can ensure aesthetics while minimizing fingerprint distress in daily use.
(2) Mirror polishing
Mirror polishing is a continuous polishing process until the surface of the stainless steel becomes extremely smooth and reflective like glass, providing maximum gloss. In food processing areas, this high gloss surface facilitates visual inspection to ensure hygiene and quality control. It is also commonly found in industrial equipment or interiors that require frequent cleaning, presenting a high-grade, sophisticated visual effect.
(3) Satin Finish
Satin Finish is a semi-reflective surface with a satin luster created by electropolishing or mechanical polishing. This finish is less prone to fingerprints or smudges and is commonly used in areas such as restroom fixtures, laboratory equipment, and architectural trim where a glossy appearance is needed to ensure aesthetics while facilitating routine cleaning and maintenance.
(4) Matte Finish
Matte finishes are made with the help of processes such as sandblasting or chemical etching and are extremely low in reflectivity. With a smoother texture than brushed, this finish is pleasant to the touch and is often used on railings, medical equipment and appliances that need to minimize glare to provide a good visual and tactile experience for the user.
