What is Brushed Stainless Steel Sheet?

Brushed stainless steel sheet is a type of sheet material whose surface texture is straight-lined through a brushing process. It boasts superior performance, including excellent physical properties, high corrosion resistance, and a beautiful, elegant appearance. The manufacturing process primarily utilizes coloring, surface finishing, and brushing techniques to enhance the layered look of this decorative metal panel.

 

 

Brushed stainless steel sheet possesses many performance characteristics, such as excellent physical properties, high corrosion resistance, good heat resistance, good thermal insulation, and aesthetic appeal. The following is an introduction to these characteristics:

 

1. Excellent Physical Properties: Tests show that colored brushed stainless steel sheet achieves Grade I-II in airtightness, Grade III in watertightness, and Grade I in strength. Therefore, brushed metal doors and windows are highly strong and can withstand 30 layers of use without rigidity issues.

 

2. High Corrosion Resistance: This metal sheet door and window material contains active elements such as chromium, which prevents electrochemical corrosion, resulting in high strength and excellent corrosion resistance. Similarly, this type of stainless steel door and window material is unmatched by any other material. Its acid resistance is many times higher than that of ordinary steel; its alkali resistance is many times higher than that of aluminum alloy.

 

3. Excellent heat resistance and insulation performance: Colored stainless steel brushed sheets have relatively slow thermal conductivity. Tested by the National Testing Center, the insulation performance of sliding windows is ≤3.1W/(square meter K), exceeding the insulation performance of other doors and windows, resulting in excellent insulation effects.

 

4. Decorative, beautiful, and durable: Colored stainless steel brushed sheet doors and windows are aesthetically pleasing and durable, mainly due to the appearance and excellent weather resistance of this high-strength material. The wall thickness of colored stainless steel door and window profiles is generally 0.6-0.7 mm. Due to its high hardness, high resilience, and good rigidity, the profile cross-section can be made larger.

 

The production of stainless steel brushed sheets mainly employs coloring, surface treatment, and brushing processes, giving the matte metal a fine, velvety luster. The following is a detailed description of the process:

 

1. Coloring process: Processing stainless steel brushed sheets to a bronze color is costly. Compared to ordinary stainless steel sheets, an additional coloring process is required. There are generally two coloring techniques: water plating and vacuum ion plating. Water plating offers better coloring effect and durability. Water-plated bronze stainless steel brushed sheets have many advantages, not only making the stainless steel's color pure and its texture dense and hard, but also giving the metal surface a moist, bright, and glossy finish.

 

2. Surface Finishing: Bronze and stainless steel brushed sheets can also be further processed through etching and sandblasting, making the layering of these metal decorative panels more prominent, surpassing the general flatness of decorative styles, and enhancing the dynamism and layering effect of interior spaces. In the colored stainless steel sheet decoration industry, commonly used materials include 201 and 304.

 

3. Brushing Process: Metal brushing is a manufacturing process that involves repeatedly scraping stainless steel sheets with sandpaper. The main process flow consists of three parts: degreasing, sanding, and washing. During the brushing process, a special coating technology after anodizing can form a film layer containing metallic components on the metal surface, clearly revealing every tiny brush mark, thus giving the matte metal a fine, hair-like luster.
