Rust removal and cleaning: Derust the flange bolts to ensure that the surface is clean and free of impurities.
Immerse in zinc liquid: Immerse the treated flange bolts in molten zinc liquid at about 500℃.
Cooling and passivation: After the dip plating is completed, the bolts need to be cooled and passivated to enhance the corrosion resistance of the coating.
