Surface Finish
Shot Blasting: Cleans and prepares surfaces using abrasive material, making them ready for coating and improving adhesion.
Sand Blasting: Uses sand particles to clean and roughen surfaces, suitable for various applications.
Pickling and Passivation: Chemical treatment removes contaminants and rust, enhancing corrosion resistance and creating a smooth surface.
Polishing: Uses abrasive material to make surfaces smooth and shiny, often for aesthetic purposes.
Electroplating: Applies a metal coating using electric current to improve corrosion resistance and appearance.
Painting and Coating: Adds a protective layer to prevent corrosion and enhance durability and appearance.
