304 Stainless Steel Sheet 4 Brushed Finish

What is a #4 finish?

A #4 finish, also known as a brushed or satin finish, is a type of surface finish applied to stainless steel raw materials. It is one of the most popular finishes used in various applications due to its attractive appearance and practical benefits. The #4 finish is achieved through a specific mechanical polishing process that creates a uniform, non-reflective, and textured surface with a fine grain pattern.

The #4 finish is obtained by mechanically polishing the stainless steel surface with abrasive materials. The process involves using progressively finer abrasives to remove any surface imperfections and scratches, resulting in a smooth and even finish. The final step involves creating a brushed texture by moving the polishing material in a consistent pattern across the surface. This brushing action produces fine parallel lines that are visible to the eye but do not create a mirror-like reflection.

● Non-Reflective: Unlike a mirror finish (#8), the #4 finish does not produce a high level of reflectivity. Instead, it offers a muted, semi-reflective appearance, making it ideal for applications where minimizing glare is desired.

● Uniform Grain Pattern: The #4 finish displays a consistent and fine grain pattern created by the brushing process. This texture adds a touch of sophistication and modernity to the stainless steel surface.

● Hides Imperfections: The brushed texture helps conceal minor surface imperfections, scratches, and fingerprints, making it a practical choice for high-traffic areas or applications that require frequent handling.

● Easy to Clean: The #4 finish is relatively easy to clean and maintain compared to finishes with a higher level of reflectivity, such as a mirror finish. Fingerprints and smudges are less noticeable on the brushed surface.

●  Architectural and Interior Design: It is commonly used for wall cladding, elevator interiors, handrails, column covers, and decorative elements in commercial and residential buildings.

Kitchen and Food Equipment: Stainless steel with a #4 finish is often used for kitchen backsplashes, countertops, sinks, and appliances.

●  Commercial and Retail Fixtures: It is used for display fixtures, signage, and decorative elements in commercial spaces and retail settings.

●  Automotive and Aerospace: Stainless steel with a #4 finish is employed for trim and decorative accents in vehicles and aircraft interiors.

●  Furniture and Home Accessories: The brushed finish is used for furniture components, handles, knobs, and other home accessories.

In summary, the #4 finish on stainless steel raw materials provides a stylish and practical option for a wide range of applications. Its non-reflective, uniform grain pattern, and ability to hide imperfections make it a popular choice in both architectural and functional contexts.
