Stainless steel rolled finishes provide both aesthetic and functional advantages for all types of stainless steel industrial applications. These unique steel finishes are available in course, flat, reflective, and non-reflective options, providing enhanced metal protection and lasting visual allure. Whether you’re looking for a stainless steel finish that protects or enhances the stainless steel’s visual appeal, several options are available to deliver the results you need.
Your application requirements will largely determine the finishing options you need. Finishing options are numbered one through eight, with higher numbers more reflective than lower numbers. Lower numbers have a matte finish, whereas higher numbers have a reflective, polished finish.
Mill finishes offer a matte finish for stainless steel. It is ideal for applications that do not require bright finishes, or durability remains the most critical factor.
The No.1D stainless steel mill finish requires hot rolling and minimal finishing to produce a uniform microstructure known as annealing to achieve its desired effect. This process results in the coarsest stainless steel finish available. The #1D finish creates a scale-like finish that is darker and more varied than other stainless steel finishes.
The #2D finish is perpetuated through a cold-rolled, annealed, and pickling process that creates a dull matte appearance that is non-reflective. The #2D finish is ideal for gutters, drainage functions, and lubricants' retention in deep drawing applications.
Providing a bright/high polish appearance, the #2B stainless steel finish is achieved through cold rolling, annealing, and pickling. The #2B finish is well-suited for solar panels and architectural applications. 304 and 316 grade stainless steels are often manufactured with a #2B finish.
BA finished stainless steel products are bright annealed with a smooth reflective surface and cold-rolled processed. BA finish is similar to the #8 mirror finish but without a clear finish and an unscaled surface. BA finish is ideal for various fabrication projects and is often viewed as a lower-cost alternative to a buffed #7 or #8 mirror finish.
Brushed stainless steel finishes offer a reflective option with parallel or patterned lines. Brushed finishes are often used for buildings and architectural applications.
Also referred to as grinding, roughing, or rough grinding, the #3 finish is a 100-120-grit option applied through a one-directional course. The #3 brushed finish requires mechanical or gradual, more refined polishing techniques via special coils or rolls. No. 3 brushed finishes are commonly used in food and beverage production services.
The No. 4 finish provides a 150-180 grit option with a bright brushed finish characterized by short, uniform parallel polishing lines. Brushed #4 finishes are widely used for kitchen and restaurant equipment, food processing, dairy equipment, hospital surfaces, highway tank trailers, control panels, and water fountains.
Hot rolled, then buffed, polished stainless steel finishes are highly reflective with a mirror-like shine. Highly reflective polished stainless steel is often used for architectural pieces or different art styles.
Defined by their high reflection and mirror-like appearance, No. 8 finishes are the most reflective according to ASTM standards. The #8 finish is created mechanically by treating the surface with progressively finer abrasives. The final process involves buffing the surface for 5-10 minutes to create a mirror-like, highly reflective finish. Additionally, a #8 finish enhances corrosion resistance, eradicating crevices that promote corrosion. Mirror finishes are used for ornamental trim, cleanrooms, mirrors, wall panels, and architectural design.
Brushed stainless steel finishes can vary due to abrasive techniques and sanding belt differences used for brushed stainless steel products. The #4 finish offers more reflective qualities and lines than the #3 finish.
Polished stainless steel finishes are mirror-like with a highly-reflective appearance.
The best stainless steel finish will depend on your project requirements. Matte finishes are suitable for industrial uses that do not require smooth surface finishes. Highly reflective polished finishes are well-suited for aesthetic and ornamental applications.
