How is Colored Stainless Steel Sheets Made

Table of Contents


Colored stainless steel sheets are a unique option for many applications because of the distinct colors they provide and the durability of the material. The colors of the colored stainless steel sheets are achieved in a variety of ways, depending on the desired outcome. The process used to create the colored stainless steel sheets begins with the steel being treated with a direct current that bonds a special chromium oxide film to the surface of the material. This processes hardens the steel and also makes it more resistant to various types of corrosion.

Coloring processes

PVC Coating

One of the most popular methods for producing colored stainless steel sheet is through Physical Vapor Deposition (PVD) coating. This process involves applying a thin layer of titanium nitride (TiN) to the surface of the stainless steel sheet. The PVD coating creates a strong, chemical bond between the stainless steel and the TiN, resulting in an incredibly durable and fade-resistant finish that can be easily tinted for any color desired.

To provide the wide range of colors available, tinted PVC sheets are then laminated to the steel using heat and pressure. The type of tint used will determine the final color of the material. Common electroplating processes include vacuum electroplating and water electroplating. This process also helps protect the colored stainless steel sheets from scratching, abrasion, and physical damage. The PVC sheets are available in a range of colors, allowing for a wide range of color options for the customer.

Powder Coating

This process involves the application of a dry powder coating material to the metal surface. This is done by infusing the powder into a compressed air gun, the operator then sprays a thin layer of the powder onto the surface. The powder then melts and binds to the surface of the metal and forms a protective membrane. This method allows for a more precise coloring than the electrolytic process, but also allows for a wide range of different shades.

Colored stainless steel sheets can also be created using a process called anodizing. In this process, the stainless steel is exposed to an electrolytic process that causes the metal to take on a range of different colors. This is done by immersing the steel in an electrolytic acid solution and introducing certain chemicals to it over time. These chemicals alter the surface of the material, causing it to take on a range of colors. The result is a highly durable and vibrant finish.

Colored Adhesive

A colored finish can be added to the stainless steel sheets by applying a colored adhesive. This method is often used when the desired color is a unique and hard to find one as this process allows the customer to customize the color. The adhesive is applied to the surface of the steel, creating a beautiful and permanent finish.

In Conclusion

Roofing and paneling are two of the more common uses of colored stainless steel sheets, but they can also be used for accent pieces such as window frames, doors, and even panels in furniture. When used indoors or outdoors, the result is an eye-catching and unique space.

Colored stainless steel sheets provide an aesthetically pleasing alternative to traditional steel and can be an ideal choice for many applications. By utilizing one of the processes outlined above, a customer can achieve a range of colors and finishes to meet the needs of the application.

With its sleek lines, color possibilities, and superior durability, colored stainless steel sheets are the perfect choice for any modern building design. Homeowners and professionals alike can now explore an endless array of color choices to enhance their interior spaces.
