About the process
The pickling and oiling derusting process is a method used to remove rust, scale, and other impurities from metal surfaces to enhance their durability and corrosion resistance. Pickling involves immersing the metal in an acid solution, typically hydrochloric or sulfuric acid, to dissolve rust and oxide layers. After pickling, the metal is thoroughly rinsed and then coated with a thin layer of protective oil to prevent immediate oxidation. This process is commonly used in steel manufacturing, metal fabrication, and automotive industries to ensure a clean, smooth surface for further processing, coating, or painting.
