If you're looking to incorporate a unique and durable material into your design scheme, consider the Black #4 Finish Stainless Steel Sheet. This article will delve into the various features of this material, which boasts a stunning surface and a wide range of applications. You'll discover that it's far more versatile than you might initially think!



What is No 4 Stainless Steel Sheet?


#4 Stainless Steel Sheet is a type of surface finish that is characterized by short, parallel polishing lines. It is processed using a #4 finishing process, which involves re-polishing the surface with a greaseless compound. This finish is most commonly used for architectural projects, appliance enclosures, and backsplashes. The natural linear texture is the most noticeable characteristic of #4 stainless steel.

Some users may confuse #4 finish with satin stainless steel, which is understandable as they are quite similar. However, for certain architectural and decoration projects that specify a satin finish, this usually refers to a type of brushed finish that has denser and coarser lines, providing a more pronounced texture. For general requirements, a #4 finish should suffice as it is more cost-effective to produce. However, if a project requires a satin finish with specific line requirements, we can customize the finish according to the user's needs.

Its slightly brushed surface provides a natural tone that conceals blemishes. It is also suitable for both indoor and outdoor decoration, making it a versatile choice for a variety of projects.

The #4 finish is a classic and widely used finish. Its applications are vast, not only can it be directly used in elevator decoration, kitchen equipment, and other metal fabrication, but it can also serve as a basic finish to be combined with other processes to create different decorative effects.

Stainless Steel Grade Options for #4 Finish


Stainless steel is a versatile material used across various industries. Its properties include corrosion resistance, ductility, formability, and durability. Among other advantages, this metal is ideal for marine and transportation applications. There are several grades of stainless steel, each with its own characteristics.

For instance, 304 stainless steel is one of the most commonly used grades. It is ideal for food processing equipment, architectural accents, and machinery parts due to its excellent corrosion resistance and formability.

Another popular grade is 316 stainless steel, known for its increased resistance to corrosion in chloride environments, making it the preferred choice for marine applications or in chemical processing and storage.

430 stainless steel, a ferritic grade, offers good corrosion resistance and is notably used in interior applications, automotive parts, and kitchen appliances.

When choosing the grade for a #4 finish stainless steel sheet, it's essential to consider the specific requirements of your project, including the environment in which the material will be used and the physical properties needed.

What to Consider When Choosing #4 Finish Stainless Steel


When selecting a #4 finish stainless steel for your project, several factors should be considered:

1. Application: The intended use of the stainless steel sheet will significantly influence your choice. For instance, if the sheet will be used in a corrosive environment, a grade with high corrosion resistance, like 316, would be ideal.

2. Aesthetics: The #4 finish provides a smooth and uniform surface with a soft satin appearance. It's perfect for applications where aesthetics are crucial, such as in architectural or interior design projects.

3. Maintenance: #4 finish stainless steel is known for its ease of maintenance. Its slightly brushed surface can conceal fingerprints and light scratches, making it a practical choice for high-traffic areas.

4. Cost: Different grades of stainless steel come at varying costs. It's essential to balance the material's cost with its benefits and the requirements of your project.

5. Durability: Stainless steel is known for its durability, but different grades offer varying levels of strength. Consider the physical stresses the material will be subjected to in its intended application.

6. Processing Method: There are two processing methods for #4 finish, plate grinding and coil grinding. For small batch orders, plate grinding is usually the only option. For the same material, specifications, and thickness, coil grinding can be considered for orders over 2 tons.

By considering these factors, you can choose the #4 finish stainless steel that best suits your project's needs.




Black #4 Finish Stainless Steel Sheets offer a unique combination of aesthetic appeal and durability, making them an excellent choice for a variety of applications. Whether you're looking for a material for your next architectural project or for use in appliance enclosures, Black #4 Finish Stainless Steel Sheets are a versatile and practical option.
