There are many options for surface treatment of sheet metal parts, which are designed to improve the corrosion resistance, aesthetics and functionality of the parts. The following are some common sheet metal surface treatment processes:
A process that mechanically forms continuous, uniform and parallel lines on the surface of sheet metal. This treatment not only enhances the aesthetics of the sheet metal, but also improves its surface wear resistance and anti-fingerprint performance. The brushed finish is widely used in aluminum sheet metal parts, such as mobile phone housings, laptop panels, etc., adding a touch of metallic texture and modernity to the product.
Physical grinding is used to remove the rough surface layer of the sheet metal, making it smooth and delicate. This treatment method not only improves the aesthetics of the sheet metal, but also enhances its surface wear resistance and corrosion resistance. It is widely used in the fields of automobiles, furniture, kitchenware and electronic products to meet occasions with high requirements for surface quality.
Powder coating is the process of spraying a uniformly mixed dry powder coating (containing resins, pigments, fillers, etc.) onto the surface of sheet metal parts. Afterward, the parts are cured at high temperatures in an oven to form a strong and beautiful coating that is often harder than traditional paint.
This coating is environmentally friendly, non-toxic, odorless, and easily recyclable, and does not release harmful volatile organic compounds during use. It can effectively enhance the corrosion and wear resistance of sheet metal parts, while providing excellent decorative effects, so that parts can maintain good appearance and performance in various environments. In addition, powder coating has good adhesion and coverage, which can ensure that the coating is closely bonded to the sheet metal substrate, improving the overall product quality and durability.
Powder coating technology not only improves the durability of parts, but also adds custom colors according to customer needs to achieve a beautiful effect. We offer 40 stock colors to choose from to speed up production turnover, and can provide different texture and gloss options upon request.
Plating and coatings serve multiple purposes, including imparting corrosion resistance, eliminating contaminants from metal surfaces, bolstering durability, and offering functional advantages. Take a look at the table below for the most preferred options.
| Finish | Descriptive Name | Specification | Compatible Material Types |
| Zinc Plating | Electroplated Zinc for Corrosion Resistance | MIL-STD-171, ASTM B633 | Steel, Stainless Steel |
| Nickel Plating | Electroplated Nickel for Enhanced Wear Resistance | ASTM B689 | Steel, Stainless Steel, Brass |
| Powder Coating | Durable Decorative Coating | Custom Specification Available | Steel, Aluminum |
| Chrome Plating | Decorative or Hard Chrome for Surface Protection | ASTM B650 | Steel, Stainless Steel, Brass |
| Passivation | Removal of Surface Contaminants on Stainless Steel | ASTM A967, QQ-P-35 | Stainless Steel |
| Phosphate Coating | Corrosion Resistance and Paint Adhesion | MIL-DTL-16232, ASTM D769 | Steel |
| Copper Plating | Electroplated Copper for Electrical Conductivity | ASTM B734 | Steel, Brass |
Anodizing is a process that places sheet metal as an anode in an electrolyte solution to form a dense aluminum oxide film on its surface through electrolysis. This treatment not only improves the corrosion resistance of sheet metal, but also adds a rich color selection (such as original color, black, etc.).
Powder spraying/baking paint uses electrostatic adsorption or high-temperature baking to form a strong and beautiful protective coating on the surface of sheet metal. During the spraying process, charged powder coating particles are adsorbed onto the surface of the sheet metal workpiece to form a uniform powder coating, which is then melted, leveled and solidified by high-temperature heating. Baking paint is achieved by spraying primer and topcoat multiple times and baking at high temperature in a dust-free constant temperature baking room to chemically react the resin and other components in the coating to form a strong and dense coating. Both technologies can significantly improve the aesthetics and corrosion resistance of sheet metal parts.

Yes, sheet metal can be painted, and it is a common method to enhance its appearance and protect it from corrosion. Painting typically involves cleaning the surface, applying a primer for better adhesion, and then adding a topcoat for durability. Powder coating is also a popular alternative, offering a more uniform and durable finish.
Yes, sheet metal can be welded using various techniques, such as MIG, TIG, or spot welding. The choice of welding method depends on the type of sheet metal, its thickness, and the application. For instance, TIG welding provides precision for thinner metals, while spot welding is effective for joining overlapping sheets.
