1. Galvanizing: Galvanizing is a protective layer of zinc obtained by point solution;

2. Baking paint: Baking paint uses thermal spraying technology to coat a layer of paint on the surface of the blind rivet body. The paint color of blind rivets can be from the RAI color card, or can be provided upon request;

3. Anodizing: Anodizing is a process in which metal is placed in the electrolyte as an anode, and an oxide film is formed on the surface of the metal, typically aluminum alloy anodizing; the anodic oxide film has high adsorption capacity and can be colored , Its color adhesion is much better than baking varnish;

4. Zinc-nickel alloy electroplating: zinc-nickel alloy electroplating is obtained by electrolysis in zinc and nickel electrolyte. Zinc-nickel alloy electroplating has better deformation and stronger corrosion resistance than pure zinc plating.
