Square grilles are available in a variety of surface treatments, each with their own specific application scenarios and advantages. Here are some common square grille finishes:
First of all, hot-dip galvanizing is a common and effective surface treatment method. This method immerses the Square grille in molten zinc liquid, causing the zinc to chemically react with the grille surface to form a dense zinc-iron alloy layer. This alloy layer not only enhances the corrosion resistance of the grille, but also
Improved its anti-rust ability and resistance to chemical corrosion. Therefore, hot-dip galvanized Square grille is particularly suitable for outdoor and humid environments, such as bridges, docks and sewage treatment plants.
Secondly, spray painting is also a common surface treatment method. By spraying a layer of anti-corrosion paint on the surface of the Square grille, such as epoxy zinc-rich paint or polyurethane paint, you can effectively prevent the grille from oxidation, corrosion, etc., thereby extending its service life. Spray paint treatment not only has good
The appearance effect is better, and different colors can be selected according to customer needs to make the grille better integrate into the surrounding environment.
In addition, cold galvanizing is also an optional surface treatment. It forms a zinc layer on the surface of the square grille through electroplating or chemical plating at normal temperature. Although the thickness of the cold galvanized layer is relatively thin, it can also provide some protection against corrosion.
In addition to the above methods, there are some other surface treatment methods, such as plastic spraying, anodizing, etc. Plastic spraying treatment is to spray a layer of plastic powder on the surface of the grille, and then bake and solidify it at high temperature to form a corrosion-resistant and beautiful coating. Anodizing is done by electrolysis
Used to form an oxide film on the surface of the grating to improve its corrosion resistance.
In general, there are various surface treatment methods for Square grille. Which method to choose mainly depends on factors such as the use environment of the grille, corrosion resistance requirements, and budget. The correct surface treatment method can not only increase the service life of the grille, but also make it better adapt to various complex environments.
